Description

Technical Field

[0001] The present invention relates to the field of ecological environment technology, and in particular to a habitat quality assessment method and device. Background Art

[0002] Habitat is of vital importance in river ecosystems. It is not only a medium for water flow and a habitat for organisms, but also directly affects biodiversity. However, the dual impacts of global climate change and human activities in recent years have led to changes in the water quantity, water quality and physical structure of many rivers. These changes have not only changed the composition of biological communities, but also led to the gradual degradation of many river ecosystems and the reduction of biodiversity.

[0003] In related technologies, river status is usually assessed based on the subjective judgment and experience of experts. The assessment results may be affected by individual subjective preferences or cognitive biases, resulting in a lack of objectivity and consistency. At the same time, complex ecological assessment results are usually presented using text descriptions or simple data tables, making it more difficult to convey information about the health of river ecosystems to decision makers, the public and stakeholders. Summary of the invention

[0004] In view of this, the present invention provides a habitat quality assessment method and device to solve the problem of insufficient objectivity and communication effect caused by relying on subjective judgment and text description in habitat quality assessment through objectivity and visualization.

[0005] In a first aspect, the present invention provides a habitat quality assessment method, comprising: obtaining habitat data of a target river section; processing the habitat data to determine target data corresponding to a plurality of preset ecological indicators; evaluating the target data according to a preset evaluation index system to obtain an actual assessment grade corresponding to the target data; wherein the evaluation index system includes a plurality of assessment grades corresponding to the ecological indicators and assessment standard data corresponding to the assessment grades; automatically generating a habitat quality assessment map corresponding to the target river section according to the actual assessment grades; wherein different assessment grades are indicated by different colors in the habitat quality assessment map.

[0006] The habitat quality assessment method provided in the embodiment of the present invention uses a preset evaluation index system and evaluation standard data for evaluation, ensuring the standardization and comparability of the evaluation. The evaluation index system includes ecological indicators, evaluation levels and evaluation standard data, which helps to comprehensively consider ecological conditions in multiple aspects and ensure the objectivity and accuracy of the evaluation results. The habitat quality assessment map is automatically generated according to the actual evaluation level. This automatic generation can help quickly understand and communicate the evaluation results. Different evaluation levels are marked with different colors in the habitat quality assessment map. This visual display method is intuitive and easy to understand, which helps decision makers and the public perceive and understand changes in ecological quality. Therefore, this method makes it easier to obtain habitat indicator data and makes the evaluation criteria clearer, thereby avoiding complex calculation processes.

[0007] In an optional embodiment, different ecological indicators constitute different ecological elements corresponding to a river section; ecological elements include geomorphic elements, hydrological elements, water quality elements, vegetation elements, and buffer zone and corridor elements; geomorphic elements include hydrological and geomorphic grade indicators, habitat type quantity indicators, and cross-sectional terrain complexity indicators; hydrological elements include runoff time indicators; water quality elements include odor indicators and transparency indicators; vegetation elements include plant layer indicators and vegetation horizontal staggered degree indicators; buffer zone and corridor elements include buffer zone width indicators and river length indicators with blocked continuity; before evaluating the target data according to a preset evaluation index system and obtaining the actual evaluation grade corresponding to the target data, the method also includes: obtaining multiple evaluation grades corresponding to the ecological indicators, and evaluation standard data corresponding to each evaluation grade; and establishing an evaluation index system based on multiple evaluation grades and evaluation standard data.

[0008] The habitat quality assessment method provided by the embodiment of the present invention covers multiple ecological factors, including landforms, hydrology, water quality, vegetation, buffer zones and corridors, etc., ensuring a comprehensive assessment of the river ecosystem in many aspects. Multiple assessment indicators are specifically listed under each ecological factor, such as hydrological and geomorphological levels, number of habitat types, odor, transparency, etc. These indicators can quantify and describe the status of different ecological factors. Obtaining multiple assessment levels corresponding to ecological indicators and using the assessment standard data corresponding to each level, this standardized method helps to ensure the objectivity and comparability of the assessment. Establishing an evaluation index system based on multiple assessment levels and standard data emphasizes the systematic and scientific nature of the assessment process, which helps to accurately reflect the health status of the river ecosystem. The target data is evaluated according to the preset evaluation index system. This preset ensures the methodology and consistency of the assessment process, making the assessment results more reliable and credible.

[0009] In an optional implementation, the target data is evaluated according to a preset evaluation index system to obtain an actual evaluation level corresponding to the target data, including: comparing the target data with evaluation standard data to determine the actual evaluation level corresponding to the target data.

[0010] The habitat quality assessment method provided by the embodiment of the present invention uses a preset evaluation index system to ensure the standardization of the assessment process, thereby improving the objectivity and credibility of the assessment. The assessment basis is compared with the assessment standard data. This method helps to establish objective assessment standards and avoid subjective bias. The target data is compared with the assessment standard data. This transparent comparison method makes the assessment results clearer and more understandable. By comparing the target data with the actual assessment level, the current actual state of the river ecosystem can be more accurately reflected. The determination of this actual assessment level helps to identify potential ecological problems or the possibility of improvement. By comparing to determine the actual assessment level, this scientific method helps to ensure the scientific nature and operability of the assessment results.

[0011] In an optional embodiment, after automatically generating a habitat quality assessment map corresponding to the target river section according to the actual assessment level, the method further includes: judging the actual assessment level according to a preset scoring standard, determining the individual scores corresponding to each ecological indicator and the comprehensive score corresponding to the target river section.

[0012] The habitat quality assessment method provided by the embodiment of the present invention uses a preset scoring standard to judge the actual assessment level, ensuring the consistency and comparability of the assessment process. All assessments are based on the same set of standards, avoiding the interference of subjective factors and making the assessment results more objective and credible. Scoring each ecological indicator separately can provide detailed assessment information on different aspects of the river ecosystem. This detail helps to accurately understand the status of each ecological indicator, so as to formulate management and protection strategies in a targeted manner. The individual scores of each ecological indicator are combined to obtain a comprehensive score for the target river section, reflecting the health status of the overall ecosystem. This comprehensive score not only intuitively shows the overall ecological quality of the river section, but also facilitates comparison with the assessment results of other regions or different time points. Based on the scoring criteria for assessment and judgment, this scientific basis helps to provide reliable data support for decision makers.

[0013] In an optional embodiment, before judging the actual evaluation level according to a preset scoring standard and determining the individual scores corresponding to each ecological indicator and the comprehensive score corresponding to the target river section, the method also includes: obtaining the scores corresponding to each evaluation level, the weights corresponding to each ecological indicator, a first preset threshold and a second preset threshold; wherein the first preset threshold is used to judge whether the current ecological indicator is a problem indicator, and the second preset threshold is used to judge whether the target river section is a problem river section; establishing a scoring standard based on the score, weight, first preset threshold and second preset threshold.

[0014] The habitat quality assessment method provided by the embodiment of the present invention can establish a clear assessment framework and standards by obtaining the scores corresponding to each assessment level, the weights of ecological indicators and preset thresholds, thereby ensuring the structuring and systematic nature of the assessment process and making the assessment results more comparable and scientific. The first and second preset thresholds are used to determine whether there are problems with ecological indicators and river sections, and potential ecological risks and problem areas can be accurately identified. The scoring criteria based on scores, weights and preset thresholds provide scientific data support for decision makers. Clear score, weight and threshold settings make the assessment process more transparent and operational.

[0015] In an optional implementation, determining the comprehensive score corresponding to the target river section includes: multiplying the individual scores by the weights and then summing them to obtain the comprehensive score.

[0016] The habitat quality assessment method provided by the embodiment of the present invention can generate a comprehensive score by multiplying and summing up each score with its corresponding weight. This comprehensive score takes into account the importance of each assessment indicator and can fully reflect the overall state or quality of the target river section. By applying different weights to different indicators, the importance of each assessment factor can be effectively weighed. Combining the single score with the weight makes the assessment result have quantitative characteristics. The method of calculating the comprehensive score is relatively direct and simple, making it easy to operate and apply, which helps to improve the efficiency of the assessment.

[0017] In an optional embodiment, after judging the actual evaluation level according to a preset scoring standard and determining the individual scores corresponding to each ecological indicator and the comprehensive score corresponding to the target river section, the method also includes: when it is determined that the current individual score corresponding to the current ecological indicator is less than a first preset threshold, determining the current ecological indicator as a problem indicator; when it is determined that the comprehensive score is less than a second preset threshold, determining the target river section as a problem river section.

[0018] The habitat quality assessment method provided by the embodiment of the present invention sets a first preset threshold value for judging whether there is a problem with the ecological indicator, which can help identify potential ecological risks or problems at an early stage. Setting a second preset threshold value for judging whether there is a problem with the target river section can assess the ecological status of the river from a global perspective. Setting a preset threshold value makes the problem identification process more standardized and operational.

[0019] In an optional implementation, before obtaining the habitat conditions of the target river section, the method further includes: segmenting the entire river to obtain a plurality of candidate river sections; and randomly selecting the plurality of candidate river sections to determine the target river section.

[0020] The habitat quality assessment method provided by the embodiment of the present invention divides the entire river into sections to ensure that the entire river system is covered, thereby comprehensively assessing its ecological status. Through this segmentation method, the ecological characteristics and problems of different parts can be captured. By randomly selecting candidate river sections, the influence of subjective preferences and selectivity can be reduced, and the objectivity and scientific nature of the assessment can be improved. Random selection can ensure that each candidate river section has an equal opportunity to be evaluated, thereby avoiding bias in the assessment results. Randomly selecting a target river section from multiple candidate river sections can improve the efficiency of the assessment process while ensuring the comprehensiveness of the assessment. The random selection method has high transparency and repeatability, and the assessment process can be clearly recorded and verified.

[0021] In a second aspect, the present invention provides a habitat quality assessment device, comprising: an acquisition module for acquiring habitat data of a target river section; a processing module for processing the habitat data to determine target data corresponding to a plurality of preset ecological indicators; an assessment module for evaluating the target data according to a preset evaluation index system to obtain an actual assessment level corresponding to the target data; wherein the evaluation index system includes a plurality of assessment levels corresponding to the ecological indicators and assessment standard data corresponding to the assessment levels; a generation module for automatically generating a habitat quality assessment map corresponding to the target river section according to the actual assessment levels; wherein different assessment levels are indicated in the habitat quality assessment map by different colors.

[0022] In a third aspect, the present invention provides a computer device, comprising: a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the habitat quality assessment method of the first aspect or any corresponding embodiment thereof by executing the computer instructions.

[0024] In a fifth aspect, the present invention provides a computer program product, comprising computer instructions for causing a computer to execute the habitat quality assessment method of the first aspect or any corresponding embodiment thereof. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0032] The health of river ecosystems is crucial to maintaining biodiversity and ecological balance. However, in recent years, global climate change and human activities such as water resource development, land use change and pollutant emissions have had a profound impact on the ecosystems of many rivers.

[0033] First, climate change has led to changes in precipitation patterns and rising temperatures, which directly affect the amount and temperature of water in rivers. These changes not only affect the growth and reproduction of aquatic organisms, but may also lead to the migration of species and changes in ecological niches in river ecosystems. For example, some cold-water fish may face the problem of habitat reduction or high water temperatures and find it difficult to survive, thus affecting the stability of the entire food web.

[0034] Secondly, human activities such as riverbank development, industrial pollution and agricultural discharge directly lead to the deterioration of river water quality. Excessive nutrients and the discharge of harmful chemicals in water bodies not only poison aquatic plants and animals, but also weaken the anti-disturbance ability of river ecosystems. These pollution sources may lead to large-scale deaths of aquatic organisms and weakening of ecosystem functions, further exacerbating the loss of biodiversity.

[0035] In terms of technical assessment, methods that traditionally rely on subjective judgment and experience of experts have problems with objectivity and consistency. Experts' subjective preferences and cognitive biases may lead to inconsistencies in assessment results, making it difficult for decision makers and the public to accurately understand the true health status of river ecosystems. In addition, complex ecological assessment results are usually presented in the form of text descriptions or simple data tables, which limits the comprehensive understanding of the state of complex ecosystems.

[0036] In view of this, the technical solution of the present invention divides the entire river into sections and randomly selects target river sections for evaluation. Through the preset evaluation index system, various ecological indicators are investigated in detail, and scores of various ecological indicators and target river sections are given according to the preset scoring criteria to determine whether there are problems with the current ecological indicators or target river sections. Finally, the geographic information system is used for evaluation and mapping, and the habitat quality assessment results of the entire river are displayed in different colors, thereby achieving a comprehensive and scientific assessment of the ecological quality of the river and providing reliable data support for effective river management and protection strategies.

[0037] According to an embodiment of the present invention, an embodiment of a habitat quality assessment method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0038] In this embodiment, a method for assessing habitat quality is provided, which can be used in computer devices, such as laptop computers, desktop computers, etc. Figure 1 is a flowchart of a habitat quality assessment method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0039] Step S101, obtaining habitat data of a target river section.

[0040] The target river section is the part of the river that is specifically selected and focused on when conducting habitat quality assessment or management. Habitat data is data that describes and records the environmental conditions for the survival and reproduction of specific biological communities or species, such as the basic conditions of the biological living environment (water quality, water temperature, dissolved oxygen, pH value, etc.), hydrological characteristics (flow rate, water depth, river width, riverbed morphology, etc.), rock structure and coverage, vegetation and habitat types, animal community structure, and human impacts. Specifically, assessors can directly conduct field observations and sampling in the target river section to obtain habitat data; they can also obtain habitat data through satellite remote sensing or drone technology, which is not limited here.

[0041] Step S102, processing the habitat data to determine target data corresponding to a plurality of preset ecological indicators.

[0042] The preset multiple ecological indicators cover all key aspects of the river ecosystem and are used to comprehensively evaluate the habitat quality and health of the target river section. For example, they may include hydrogeomorphological grade indicators, habitat type quantity indicators, and cross-section terrain complexity indicators. The target data can be directly used in the final data set corresponding to the preset multiple ecological indicators after processing and preparation. Specifically, the habitat data is cleaned and quality controlled, including removing erroneous data, correcting inconsistent data, and processing missing values. The cleaned and quality-controlled data from different sources and formats are integrated into a unified data set, and the data are processed and prepared using methods such as statistical analysis, spatial analysis, or model building so that the habitat data can better reflect the requirements of the ecological indicators. The processed habitat data is mapped and associated with the preset multiple ecological indicators, and the mapped data is verified and checked to ensure the accuracy and credibility of the data.

[0043] Step S103, evaluating the target data according to a preset evaluation index system to obtain an actual evaluation level corresponding to the target data; wherein the evaluation index system includes multiple evaluation levels corresponding to ecological indicators and evaluation standard data corresponding to the evaluation levels.

[0044] The preset evaluation index system is a set of standardized indicators and evaluation methods for evaluating the health status of river ecosystems that are determined and defined in advance before conducting habitat quality assessment. The evaluation index system can be jointly developed by environmental scientists, ecologists, policy makers and relevant stakeholders to provide consistency and comparability for the evaluation of ecosystems or environments. The actual evaluation grade is the result obtained after evaluating the target data according to the preset evaluation index system, which is used to describe the state or level of a specific ecological indicator under given conditions. The actual evaluation grade may include one or more of excellent, good, medium, poor, and extremely poor. Specifically, according to the preset evaluation index system, the specific value of each evaluation index is calculated or extracted. The calculated result or extracted value of each evaluation index is compared with the standards defined in the evaluation index system, which include numerical ranges of different levels or categories or specific thresholds. According to the comparison results of the indicators and the standards, the corresponding level or category of each evaluation index in the evaluation system is determined.

[0045] Step S104, automatically generating a habitat quality assessment map corresponding to the target river section according to the actual assessment level; wherein different assessment levels are indicated by different colors in the habitat quality assessment map.

[0046] The habitat quality assessment map is used to visually display and analyze the ecological environment quality of the target river section. It is generated based on the ecological survey and assessment data previously conducted in the area, reflecting the habitat conditions and quality levels of different locations or regions. Specifically, a pre-defined habitat quality assessment grading system is obtained, and the color coding corresponding to each grade in the assessment map is determined. For example, blue can be used to represent excellent, green to represent good, yellow to represent medium, orange to represent poor, and red to represent extremely poor, ensuring that the color coding is clear and easy to understand. The collected assessment data is imported into the Geographic Information System (GIS) software, and the corresponding layer or image is created in the GIS based on the geographical location information of the target river section. In the GIS software, a habitat quality assessment map is created using the collected data and the defined color coding.

[0047] The habitat quality assessment method provided in the embodiment of the present invention uses a preset evaluation index system and evaluation standard data for evaluation, ensuring the standardization and comparability of the evaluation. The evaluation index system includes ecological indicators, evaluation levels and evaluation standard data, which helps to comprehensively consider ecological conditions in multiple aspects and ensure the objectivity and accuracy of the evaluation results. The habitat quality assessment map is automatically generated according to the actual evaluation level. This automatic generation can help quickly understand and communicate the evaluation results. Different evaluation levels are marked with different colors in the habitat quality assessment map. This visual display method is intuitive and easy to understand, which helps decision makers and the public perceive and understand changes in ecological quality. Therefore, this method makes it easier to obtain habitat indicator data and makes the evaluation criteria clearer, thereby avoiding complex calculation processes.

[0048] In this embodiment, a method for assessing habitat quality is provided, which can be used in computer devices, such as laptop computers, desktop computers, etc. Figure 2 is a flowchart of a habitat quality assessment method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0049] Step S201, obtain the habitat data of the target river section. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0050] Step S202: Process the habitat data to determine target data corresponding to multiple preset ecological indicators. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0051] Step S203, obtaining multiple evaluation levels corresponding to the ecological indicators and evaluation standard data corresponding to each evaluation level.

[0052] As shown in Table 1, different ecological indicators constitute different ecological elements corresponding to river sections; ecological elements include geomorphic elements, hydrological elements, water quality elements, vegetation elements, and buffer zone and corridor elements; geomorphic elements include hydrological and geomorphic grade indicators, habitat type quantity indicators, and cross-sectional terrain complexity indicators; hydrological elements include runoff time indicators; water quality elements include odor indicators and transparency indicators; vegetation elements include plant layer indicators and vegetation horizontal staggered degree indicators; buffer zone and corridor elements include buffer zone width indicators and river length indicators with blocked continuity.

[0053] Table 1

[0054]

[0055] The multiple evaluation levels corresponding to the ecological indicators can reflect the health of the river section. Specifically, the ecological indicators can be set to be divided into five levels, such as A, B, C, D, and E.

[0056] The assessment standard data corresponding to each assessment level are specifically used to determine the status or quality level of ecological indicators at different levels. These data can be quantitative or qualitative measurement results, indicator values ​​or descriptions, which are used to support assessors in classifying the status of river sections according to the set levels, as shown in Table 2-11.

[0057] Table 2 includes five levels corresponding to the hydrogeomorphological grade index and the evaluation standard data corresponding to the five levels. Specifically, the hydrogeomorphological grade index is a characteristic index used to evaluate river connectivity.

[0058] Table 2

[0059]

[0060] Table 3 includes the five levels corresponding to the habitat type quantity index and the evaluation standard data corresponding to the five levels. Specifically, the main habitat types are divided into 15 types, including comprehensive habitats, physical habitats, and biological habitats. In the target river section, the more habitat types there are, the higher the habitat diversity.

[0061] Table 3

[0062] grade Evaluation standard data A: Many Number of habitat types ≥ 10 B: More Number of habitat types: 7-9 C: Medium Number of habitat types: 4-6 D: Less Number of habitat types: 2-3 E: Very rare The number of habitat types is less than 2

[0063] Table 4 includes five levels corresponding to the cross-sectional terrain complexity index and the evaluation standard data corresponding to the five levels. Specifically, the cross-sectional terrain complexity index is an index used to evaluate the homogenization degree of the river cross section, that is, the channelization degree.

[0064] Table 4

[0065]

[0066] Table 5 includes five levels corresponding to the runoff time index and the evaluation standard data corresponding to the five levels. Specifically, the runoff time index is used as a characteristic index to characterize the hydrological conditions of rivers. The continuous flow of rivers and the flow rate that meets the needs of organisms are conducive to the functional protection of water ecosystems. The hydrological condition is one of the natural endowments and is closely related to natural factors such as climate and topography. However, it has long been damaged or changed by unreasonable human interference. Therefore, it is also used as one of the characteristic indicators reflecting the problems of water ecosystems.

[0067] Table 5

[0068]

[0069] Table 6 includes five levels corresponding to the odor index and evaluation standard data corresponding to the five levels. Specifically, the odor index represents one of the water quality indicators that can be measured and identified on site.

[0070] Table 6

[0071]

[0072] Table 7 includes five levels corresponding to the transparency index and evaluation standard data corresponding to the five levels. Specifically, the transparency index represents one of the water quality indicators that can be measured and identified on site.

[0073] Table 7

[0074]

[0075] Table 8 includes five levels corresponding to the plant layer index and the evaluation standard data corresponding to the five levels. Specifically, the plant layer index is used to evaluate the vertical stratification of vegetation. The more vertical stratification of vegetation, the better the vertical structure and richness of vegetation. Generally, the condition containing 4-5 layers of vegetation is considered to be ecologically good.

[0078] Table 9 includes five levels corresponding to the vegetation horizontal interlacing index and the evaluation standard data corresponding to the five levels. Specifically, a high vegetation coverage and a compact interlocking between communities indicate that the vegetation has a good horizontal structure.

[0079] Table 9

[0080]

[0081] Table 10 includes five levels corresponding to the buffer zone width index and the evaluation standard data corresponding to the five levels. Specifically, the buffer zone width index is used as a key indicator to identify the buffer zone problems on both sides of the river. The wider the buffer zone, the more fully it can play its ecological functions such as pollutant interception and filtration and amphibian survival and habitat.

[0084] Table 11 includes five levels corresponding to the continuity-blocked river length index and the evaluation standard data corresponding to the five levels. Specifically, the continuity-blocked river length index is represented by the sum of the lengths of the corridors blocked within a total of 1 km upstream and downstream of the river section.

[0085] Table 11

[0086] level Evaluation standard data Grade A: Excellent <200m B: Good 200-300m C-level: Medium 300-400m D-grade: Poor >400 E: Very bad >500

[0087] The habitat quality assessment method provided by the embodiment of the present invention covers multiple ecological factors, including landforms, hydrology, water quality, vegetation, buffer zones and corridors, etc., ensuring a comprehensive assessment of the river ecosystem in many aspects. Multiple assessment indicators are specifically listed under each ecological factor, such as hydrological and geomorphological levels, number of habitat types, odor, transparency, etc. These indicators can quantify and describe the status of different ecological factors. Obtaining multiple assessment levels corresponding to ecological indicators and using the assessment standard data corresponding to each level, this standardized method helps to ensure the objectivity and comparability of the assessment. Establishing an evaluation index system based on multiple assessment levels and standard data emphasizes the systematic and scientific nature of the assessment process, which helps to accurately reflect the health status of the river ecosystem. The target data is evaluated according to the preset evaluation index system. This preset ensures the methodology and consistency of the assessment process, making the assessment results more reliable and credible.

[0088] Step S204: establishing an evaluation index system according to multiple evaluation levels and evaluation standard data.

[0089] The evaluation standard data corresponding to different evaluation levels are integrated and analyzed to determine the performance of each ecological indicator at different levels. Specifically, the ultimate goal of establishing an evaluation index system is to provide an objective and systematic evaluation tool to help managers, policy makers and scientists understand and manage the status of ecosystems. Through this system, it is possible to track the changing trends of river sections, evaluate the effects of environmental policies or management measures, and provide a scientific basis for protecting and restoring river ecosystems.

[0090] Step S205, evaluating the target data according to a preset evaluation index system to obtain an actual evaluation level corresponding to the target data; wherein the evaluation index system includes multiple evaluation levels corresponding to ecological indicators and evaluation standard data corresponding to the evaluation levels.

[0091] Specifically, the above step S205 includes: comparing the target data with the evaluation standard data, and determining the actual evaluation level corresponding to the target data.

[0092] Compare the target data with the evaluation standard data of each evaluation level in terms of numerical values ​​or indicators. For example, compare whether the measured number of plant layers falls within the set range of grade A, grade B or other grades. According to the results of the comparison, determine the actual evaluation grade, which is the grade that best matches the target data and reflects the current status or quality level of the ecological indicator.

[0093] Step S206, automatically generate a habitat quality assessment map corresponding to the target river section according to the actual assessment level; different assessment levels are marked with different colors in the habitat quality assessment map. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0094] The habitat quality assessment method provided by the embodiment of the present invention uses a preset evaluation index system to ensure the standardization of the assessment process, thereby improving the objectivity and credibility of the assessment. The assessment basis is compared with the assessment standard data. This method helps to establish objective assessment standards and avoid subjective bias. The target data is compared with the assessment standard data. This transparent comparison method makes the assessment results clearer and more understandable. By comparing the target data with the actual assessment level, the current actual state of the river ecosystem can be more accurately reflected. The determination of this actual assessment level helps to identify potential ecological problems or the possibility of improvement. By comparing to determine the actual assessment level, this scientific method helps to ensure the scientific nature and operability of the assessment results.

[0095] In this embodiment, a method for assessing habitat quality is provided, which can be used in computer devices, such as laptop computers, desktop computers, etc. Figure 3 is a flowchart of a habitat quality assessment method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0096] Step S301, segmenting the entire river to obtain multiple candidate river segments; and randomly selecting the multiple candidate river segments to determine the target river segment.

[0097] Candidate river sections are a series of river sections that may be selected for detailed investigation or evaluation after a section survey of the entire river according to specific methods and standards. The target river section is a specific river section randomly selected from the candidate river sections after the section survey of the river for detailed investigation, evaluation or monitoring. This selection is based on a series of considerations to ensure that the selected river section can represent the characteristics and conditions of the entire river. Specifically, the uniform segmentation method and the characteristic segmentation method can be used to segment the entire river. Among them, if the entire river is surveyed, it starts from the estuary and is evenly segmented from downstream to upstream. Each section is a survey unit. The length of the river channel of the survey unit should be 10 times the width of the river flat beach, with a minimum of 100m and a maximum of no more than 200m. If a segmented sampling survey is used, the river channel is first segmented, and the segmentation is based on the principle that the longitudinal slope of the river channel, whether there are embankments / bank protection, whether there are transverse dams / gates, etc. remain basically consistent within the section. The length of each section can be different, generally not more than 2km. Randomly select survey units in the divided river sections to conduct surveys. The results of the survey unit represent the overall condition of a river section. Use a random number generator or statistical software to randomly select from the candidate river sections to obtain the target river section.

[0098] The habitat quality assessment method provided by the embodiment of the present invention divides the entire river into sections to ensure that the entire river system is covered, thereby comprehensively assessing its ecological status. Through this segmentation method, the ecological characteristics and problems of different parts can be captured. By randomly selecting candidate river sections, the influence of subjective preferences and selectivity can be reduced, and the objectivity and scientific nature of the assessment can be improved. Random selection can ensure that each candidate river section has an equal opportunity to be evaluated, thereby avoiding bias in the assessment results. Randomly selecting a target river section from multiple candidate river sections can improve the efficiency of the assessment process while ensuring the comprehensiveness of the assessment. The random selection method has high transparency and repeatability, and the assessment process can be clearly recorded and verified.

[0099] Step S302: Obtain habitat data for the target river segment. Figure 2 Step S201 of the illustrated embodiment will not be described in detail here.

[0100] Step S303: Process the habitat data to determine target data corresponding to multiple preset ecological indicators. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0101] Step S304: evaluate the target data according to the preset evaluation index system to obtain the actual evaluation level corresponding to the target data; wherein the evaluation index system includes multiple evaluation levels corresponding to the ecological indicators and evaluation standard data corresponding to the evaluation levels. Figure 2Step S205 of the illustrated embodiment will not be described in detail here.

[0102] Step S305: automatically generate a habitat quality assessment map corresponding to the target river section according to the actual assessment level; different assessment levels are marked with different colors in the habitat quality assessment map. Figure 2 Step S206 of the illustrated embodiment will not be described in detail here.

[0103] Step S306, obtain the scores corresponding to each evaluation level, the weights corresponding to each ecological indicator, the first preset threshold and the second preset threshold; wherein the first preset threshold is used to determine whether the current ecological indicator is a problem indicator, and the second preset threshold is used to determine whether the target river section is a problem river section.

[0104] The quality of river habitats is divided into five levels, each level corresponding to a different score, for example, excellent is 10 points, good is 8 points, fair is 6 points, poor is 4 points, and extremely poor is 2 points. These scores reflect the performance of each ecological indicator in the assessment. The higher the score, the better the habitat quality.

[0105] The weight of an ecological indicator specifies the relative importance of the ecological indicator in the comprehensive score. For example, if a certain ecological indicator has a greater impact on the overall habitat quality, it should have a higher weight. However, in order to improve the estimation efficiency, the weights of each ecological indicator can be set to the same size.

[0106] The first preset threshold is used to determine whether the current ecological indicator is a problem indicator. Specifically, when the actual score of a certain ecological indicator is lower than the first preset threshold, it indicates that there is a problem with the indicator in the current river section.

[0107] The second preset threshold is used to determine whether the target river section is a problematic river section. If the comprehensive score of the target river section is lower than the second preset threshold, it means that the overall habitat quality of the river section is poor and is classified as a problematic river section.

[0108] Step S307, establishing a scoring standard according to the score, weight, first preset threshold and second preset threshold.

[0109] The scores, weights, first preset thresholds, and second preset thresholds determined in the above steps are integrated together to establish a comprehensive scoring standard, as shown in Table 12. The scoring standard can be described in the form of a table, algorithm, or calculation formula to ensure the transparency and operability of the evaluation process.

[0111]

[0112] The habitat quality assessment method provided by the embodiment of the present invention can establish a clear assessment framework and standards by obtaining the scores corresponding to each assessment level, the weights of ecological indicators and preset thresholds, thereby ensuring the structuring and systematic nature of the assessment process and making the assessment results more comparable and scientific. The first and second preset thresholds are used to determine whether there are problems with ecological indicators and river sections, and potential ecological risks and problem areas can be accurately identified. The scoring criteria based on scores, weights and preset thresholds provide scientific data support for decision makers. Clear score, weight and threshold settings make the assessment process more transparent and operational.

[0113] Step S308, judging the actual evaluation level according to the preset scoring standard, determining the individual scores corresponding to each ecological indicator and the comprehensive score corresponding to the target river section.

[0114] The actual assessment level is judged according to the preset scoring criteria, and the score corresponding to the actual assessment level is determined. For example, when the actual assessment level is A, the score corresponding to the current ecological indicator is determined to be 10 points. The individual scores of all ecological indicators are weighted and accumulated according to their weights in the overall assessment to obtain a comprehensive score for the target river section, which reflects the overall health status or environmental quality level of the entire river section.

[0115] Specifically, the above step S308 includes: multiplying the single score by the weight and then summing them up to obtain a comprehensive score.

[0116] The individual score of each ecological indicator is multiplied by its corresponding weight in order to weight the score of each indicator according to its importance and reflect its relative contribution in the overall assessment. The product results of all ecological indicators are accumulated to obtain the comprehensive score of the target river section.

[0117] The habitat quality assessment method provided by the embodiment of the present invention uses a preset scoring standard to judge the actual assessment level, ensuring the consistency and comparability of the assessment process. All assessments are based on the same set of standards, avoiding the interference of subjective factors and making the assessment results more objective and credible. Scoring each ecological indicator separately can provide detailed assessment information on different aspects of the river ecosystem. This detail helps to accurately understand the status of each ecological indicator, so as to formulate management and protection strategies in a targeted manner. The individual scores of each ecological indicator are combined to obtain a comprehensive score for the target river section, reflecting the health status of the overall ecosystem. This comprehensive score not only intuitively shows the overall ecological quality of the river section, but also facilitates comparison with the assessment results of other regions or different time points. Based on the scoring criteria for assessment and judgment, this scientific basis helps to provide reliable data support for decision makers.

[0118] Step S309, when it is determined that the current single score corresponding to the current ecological indicator is less than the first preset threshold, the current ecological indicator is determined as a problem indicator; when it is determined that the comprehensive score is less than the second preset threshold, the target river section is determined as a problem river section.

[0119] According to the calculated single score, it is compared with the first preset threshold. If the single score of the current ecological indicator is less than the first preset threshold, it usually indicates that there is a problem with the indicator or it deviates from the ideal state. In this case, the ecological indicator will be marked as a problem indicator, requiring special attention and possible management measures.

[0120] The calculated comprehensive score of the target river section is compared with the set second preset threshold. If the comprehensive score of the target river section is less than the second preset threshold, it usually indicates that the ecosystem status of the entire river section is not ideal or there are problems. In this case, the target river section will be marked as a problematic river section, and more stringent management measures or protection measures may be required to improve its ecological environment quality.

[0121] The habitat quality assessment method provided by the embodiment of the present invention sets a first preset threshold value for judging whether there is a problem with the ecological indicator, which can help identify potential ecological risks or problems at an early stage. Setting a second preset threshold value for judging whether there is a problem with the target river section can assess the ecological status of the river from a global perspective. Setting a preset threshold value makes the problem identification process more standardized and operational.
