Description

Technical Field

[0001] This application relates to the technical field of ecological sensitivity analysis, and particularly relates to an ecological sensitivity analysis method and system based on estuaries. Background Art

[0002] Ecological environment sensitivity refers to the degree of sensitivity of an ecosystem to natural and human activity disturbances within a region. It reflects the ease and likelihood of ecological environment problems occurring in the regional ecosystem when encountering disturbances. The ecological sensitivity analysis of estuaries plays an important role in evaluating ecological security, ecosystem vulnerability, ecological function zoning, etc. It helps to comprehensively understand the constraints imposed by natural resources and human activities in a specific area on that area, thereby guiding decision-makers to formulate measures that comply with the principles of sustainability and optimize the balance of economic benefits and social well-being. In the analysis and evaluation of ecological sensitivity, the species in the ecosystem are particularly important. In existing evaluations, only the change in the number of species is used for evaluation. Since the number of species is affected by multiple factors and the data is relatively single, the reliability of the results is low. Therefore, using ordinary ecological sensitivity analysis will lead to inaccurate evaluation of ecological sensitivity in the estuary area. Summary of the Invention

Brief Description of the Drawings

[0017] Figure 1 It is a schematic diagram of the specific steps of an embodiment of a method for ecological sensitivity analysis based on an estuary according to the present invention.

[0018] Figure 2 It is a schematic diagram of the module connection of an embodiment of a system for ecological sensitivity analysis based on an estuary according to the present invention. Detailed Embodiment

[0019] The following combines the embodiments and Figure 1 - Figure 2 further elaborates on the present invention in detail, but the implementation manners of the present invention are not limited thereto.

[0020] The present invention discloses a method for ecological sensitivity analysis based on an estuary, which specifically includes the following steps: Step S1: Collect the species data of the estuary area, and obtain the basic adaptation value of the estuary ecological environment according to the species data analysis.

[0021] Step S2: Collect the historical ecological data of the estuary area, and obtain the ecological adaptation value of the estuary ecological environment according to the historical ecological data analysis.

[0022] Step S3: Combine the basic adaptation value and the ecological adaptation value to obtain the ecological environment adaptation value of the estuary area.

[0023] Set the weight ratios of the basic adaptation value and the ecological adaptation value respectively, and calculate the ecological environment adaptation value according to the weight ratios. When the basic adaptation value and the ecological adaptation value are higher, it indicates that the adaptability of this ecosystem is stronger, and thus the ecological environment adaptation value is higher.

[0024] Step S4: Obtain the climate data of the estuary area, and estimate the amount of human activities in the estuary area according to the climate data.

[0025] Step S5, obtain human activity data, and evaluate the environmental protection awareness of humans in the estuary area based on the human activity data.

[0026] Step S6, analyze the human ecological damage degree in the estuary area by combining the human activity volume and the environmental protection awareness degree, and evaluate the ecological sensitivity value of the estuary by combining the ecological environment adaptation value.

[0027] In practical applications, the proportionality coefficients of the human activity volume and the environmental protection awareness degree are set respectively, and the ecological damage degree is calculated according to the proportionality coefficients. Human activities will interfere with the ecological environment. The greater the human activity volume, the more serious the ecological damage. And the higher the environmental protection awareness, the lower the ecological damage, so the ecological damage degree is lower. The proportionality factors of the ecological damage degree and the ecological environment adaptation value are set respectively, and the ecological sensitivity value of the estuary is calculated according to the proportionality factors. The ecological sensitivity of the ecological environment refers to the degree of difficulty and the probability of occurring ecological environment problems. Therefore, the ecological sensitivity comes from external influences on the one hand, that is, the greater the ecological damage degree, the greater the ecological sensitivity. On the other hand, it comes from internal influences, that is, the higher the ecological environment adaptation value, the smaller the ecological sensitivity. A smaller ecological sensitivity means that the ecosystem has stronger resistance and resilience to external disturbances and can maintain the relative stability of its structure and function. While a larger ecological sensitivity indicates that the ecosystem is relatively fragile and is easily affected by external disturbances. It is more accurate to jointly evaluate the ecological sensitivity of the estuary through internal and external influences.

[0028] The steps of collecting species data in the estuary area and obtaining the basic adaptation value of the estuary ecological environment according to the species data are specifically as follows: Step S11, extract the species existing in the ecological environment of the estuary area from the species data and record them as estuary species.

[0029] Step S12, obtain the survival data of the estuary species, and statistically obtain the species adaptability of the estuary species according to the survival data.

[0030] Step S13, obtain the environmental data of the estuary area, and judge the species regulation ability of the estuary species according to the environmental data.

[0031] Step S14, calculate the species adaptation value by calculating the species adaptability and the species regulation ability according to the preset proportionality coefficient.

[0032] The greater the species adaptability, the stronger the species' adaptability ability and the less likely it is to be affected by external disturbances, so the species adaptation value is greater. The greater the species regulation ability, the more the species can adjust in time when the external environment changes to reduce the impact on itself, so the species adaptation value is also greater.

[0033] Step S15: Count the number of species in different estuaries based on species data, form a weight ratio according to the number of estuary species, and sum the species fitness values and the corresponding weight ratios to obtain the basic fitness value of the estuary ecological environment.

[0034] In practical applications, a weight ratio is formed according to the number of estuary species, and then multiplied by the corresponding species fitness value and summed up to obtain the basic fitness value. For example, there are estuary species A, B, and C, with the numbers of 100,000, 200,000, and 700,000 respectively, then the weight ratios are 10%, 20%, and 70%. The species fitness values of estuary species A, B, and C are 50, 60, and 80 respectively, then the basic fitness value is 50×10% + 60×20% + 70×80% = 73. There is a mutually promoting relationship between the adaptation ability of a species and the adaptation ability of the ecological environment. The adaptation behavior of a species helps to improve the conditions of its ecological environment, thereby enhancing the adaptation ability of the entire ecosystem. Therefore, based on the species composition of the ecological environment, the basic fitness value of the ecological environment can be initially obtained.

[0035] The steps to obtain the survival data of estuary species and count the species adaptability of estuary species based on the survival data are as follows: Step S121: Obtain the ecological factors affecting the survival of estuary species, denoted as influencing factors, and extract the environmental data of the surviving estuary species according to the survival data.

[0036] There are various ecological factors affecting the survival of estuary species, such as the salinity, water temperature, dissolved oxygen, etc. of the river water.

[0037] Step S122: Extract the extreme value ranges of the influencing factors from the environmental data of the surviving estuary species.

[0038] Estuary species usually do not live in only one environment. Here, the environment does not include the estuary environment. The environmental ranges in which the influencing factors can survive can be extracted from multiple other environments. For example, species A lives in locations A, B, and C, and the water temperature ranges in the three locations are -1℃ - 5℃, -10℃ - 10℃, and 5℃ - 15℃ respectively, then the extreme value range of temperature is -10℃ - 15℃.

[0039] Step S123: Sum the differences of the extreme value ranges of all influencing factors to obtain the species adaptability of the estuary species.

[0040] To sum the extreme value ranges, first calculate the differences between the extreme value ranges and then sum them up. For example, if the extreme value range of water temperature is -10℃ - 15℃, then the difference is 25. If the extreme value range of salinity is 5g / L - 18g / L, then the difference is 13. Add 25 and 13 to obtain the species adaptability of 38.

[0041] Step S124: Aggregate the extreme value ranges of all influencing factors to form the survival range of estuarine species.

[0042] In practical applications, aggregating all the extreme value ranges to obtain the survival range of estuarine species indicates that estuarine species can survive within this range. For example, the extreme value range of water temperature is -10°C - 15°C, and the extreme value range of salinity is 5 g / L - 18 g / L, and these are used as the ranges within which estuarine species can survive.

[0043] The steps to obtain the species regulation ability of estuarine species based on the environmental data of the estuarine area by judging the environmental data are as follows: Step S131: Obtain the survival history data of estuarine species, and extract the existence duration, current quantity, and original form of estuarine species based on the survival history data.

[0044] Step S132: Obtain the real-time form of estuarine species, and compare to obtain the morphological similarity between the original form and the real-time form.

[0045] Compare the similarity between the original form and the real-time form through existing similarity models, such as cosine similarity, etc.

[0046] Step S133: Combine the existence duration, current quantity, and morphological similarity to obtain the basic regulation ability of estuarine species.

[0047] Set the weight ratios of the existence duration, current quantity, and morphological similarity respectively, and calculate the basic regulation ability of estuarine species according to the weight ratios. The longer a species has existed on Earth, the more environmental changes it has experienced. This prompts the species to continuously accumulate adaptive characteristics during the long process of evolution to cope with various environmental changes. The current quantity of a species to a certain extent reflects its ability to adapt to the environment. Species with a larger quantity usually have stronger survival and reproduction abilities and can maintain the stability of the population under various environmental conditions. When there are significant differences between the original form and the real-time form of a species, it indicates that the species has undergone significant adaptive changes during the process of evolution, and thus has a stronger ability to regulate the environment.

[0048] Step S134: Judge whether the environmental data of the estuarine area is within the survival range of estuarine species. If it is within the survival range of estuarine species, then use the basic regulation ability as the species regulation ability of estuarine species.

[0049] For example, if the survival range of water temperature is 5°C - 15°C, and the water temperature environment of the estuary is 0°C - 10°C, then it is not within the survival range.

[0050] Step S135: If it is not within the survival range of estuarine species, then compare the difference between the environmental data and the survival range, and combine the basic regulation ability to obtain the species regulation ability.

[0051] In actual application, if the estuary environment is not within the survival range, it indicates that when the species reaches the estuary area for survival, further adjustments have been made according to the estuary environment, indicating that the species' adjustment ability is greater than expected. Therefore, it is necessary to further confirm and analyze in combination with the basic adjustment force.

[0052] If it is not within the survival range of the estuary species, then the steps to obtain the species adjustment force by comparing the difference between the environmental data and the survival range and combining the basic adjustment force are as follows: Step S1351: Extract the range of the influencing factors in the estuary area from the environmental data and record it as the real-time range.

[0053] For example, if the influencing factor is water temperature, then extract the water temperature range in the estuary area as the real-time range.

[0054] Step S1352: Compare the real-time range with the survival range, and find the influencing factors whose real-time range is not within the survival range and record them as variable factors.

[0055] Because there are many influencing factors, not every influencing factor's range is not within the survival range. For example, if the water temperature range is not within the survival range, then record the water temperature as a variable factor. While the salinity range is within the survival range, then do not record the salinity as a variable factor.

[0056] Step S1353: Calculate the range difference between the real-time range of the variable factor and the corresponding survival range.

[0057] For example, if the variable factor is water temperature, the survival range of water temperature is 5°C - 15°C, and the real-time range is 0°C - 10°C, then the minimum value difference is 5, and the maximum value is within the survival range, so the range difference is 5. The range difference calculates the difference when the real-time range is not within the survival range. If the real-time range is 0°C - 20°C, then the maximum value difference is 5, and adding the minimum value difference of 5, the range difference is 10.

[0058] Step S1354: Accumulate all the range differences to obtain the environmental adjustment force of the estuary species, and combine the environmental adjustment force and the basic adjustment force to obtain the species adjustment force.

[0059] In actual application, when the range difference is larger, it indicates that the adjustment ability of the species is greater because the species can adapt to a larger environmental range. Set the weight ratios of the environmental adjustment force and the basic adjustment force respectively, and calculate the species adjustment force according to the weight ratios. When the species adapts to the new environment in the estuary area, its adjustment ability is further improved. Therefore, combine the basic adjustment force to obtain the actual adjustment force in the area. When both the environmental adjustment force and the basic adjustment force are larger, the species adjustment force is also larger.

[0060] The steps of collecting historical ecological data in the estuary area and obtaining the ecological adaptation value of the estuary ecological environment based on the historical ecological data are as follows: Step S21: Obtain the human activities that affect the survival of estuary species, which are recorded as influencing activities, and count the changes in the number of estuary species under different influencing activities to form an influencing activity - species number change curve.

[0061] Some human activities will affect the survival of estuary species. For example, sewage discharge, fishing, etc. These human activities will all reduce the number of species, thus leading to changes in the number of species. The change in the number of species refers to the situation of the reduced or increased number of species. Calculate the average value of the number change for each activity to form an influencing activity - species number change curve. For example, sewage discharge in Area A causes a reduction of 10,000 individuals of Species A, and originally there were 20,000 individuals of Species A, so the reduction is 50%. The same degree of sewage discharge in Area B causes a reduction of 20,000 individuals of Species A, and originally there were 100,000 individuals of Species A, so the reduction is 20%. The average value is 35%. Therefore, the corresponding change in the number of species for the sewage discharge activity is a reduction of 35%. Establish a curve based on different degrees of sewage discharge, that is, there is a one - to - one corresponding change in the number of species for multiple degrees of sewage discharge, so a curve can be formed. And different influencing activities have their corresponding influencing activity - species number change curves.

[0062] Step S22: Count the historical activity data in the estuary area, and find the corresponding change in the number of species (recorded as the standard number change) from the influencing activity - species number curve according to the historical activity data.

[0063] Find the curve coordinate points corresponding to the influencing activities with the same type and degree as the historical activity in the influencing activity - species number curve according to the historical activity, and then find the corresponding change in the number of species according to these curve coordinate points. For example, if the sewage discharge pollution degree is 0.5 mg / L and the corresponding change in the number of species is a reduction of 5%, then the standard number change is a reduction of 5%.

[0064] Step S23: Find the change in the number of estuary species corresponding to the historical activity data in the estuary area, which is recorded as the real - time number change.

[0065] Count the actual change in the number of species. For example, when the sewage discharge pollution degree is 0.5 mg / L, in fact, the number of species is reduced by 8%, then the real - time number change is a reduction of 8%.

[0066] Step S24: Calculate the difference between the standard number change and the real - time number change, and sum up the differences in quantity under all influencing activities to obtain the ecological adaptation value.

[0067] For example, if the quantity difference of sewage discharge is -3% and the quantity difference of fishing is 5%, then the ecological adaptation value is 2%. A negative value indicates that the species is more harmed when living in the estuary area, while a positive value indicates that the species is better protected by the estuary ecological environment when living in the estuary area.

[0068] In practical applications, the adaptation ability of a species and the adaptation ability of the ecological environment are interdependent. The adaptation ability of a species depends not only on its own genetic and physiological characteristics but also on the ecological environment in which it is located. Human activities will have a direct impact on organisms, resulting in changes in the species quantity, and due to the influence of the ecological environment, the quantity will also change. For example, if the standard quantity change is a decrease of 5% and the real-time quantity change is a decrease of 8%, in the estuary ecological environment, under the same pollution situation, the quantity in the estuary area decreases more, indicating that the protection ability of this ecological environment is very poor and the ecological adaptation value is relatively low. If the real-time quantity change is a decrease of 3%, it means that the ecological environment plays a certain protective role, the harm to the species is reduced, and it also reflects that the adaptation ability of this ecological environment is stronger and the ecological adaptation value is larger.

[0069] The steps for obtaining the climate data of the estuary area and estimating the amount of human activities in the estuary area based on the climate data are specifically as follows: Step S41: Statistically analyze the average amount of human activities under different climates and establish a climate-human activity quantity table.

[0070] The estuary area is different from other land areas. The activities in the estuary area are affected by the climate. For example, on sunny days, with sufficient sunlight and relatively high water temperature, this is conducive to the activity and reproduction of aquatic organisms. Therefore, fishermen will choose to carry out fishing activities on sunny days because fish are more active at this time and the success rate of fishing is relatively high. On rainy days, due to the increase in rainfall and river flow, the water quality in the estuary waters may change, such as a decrease in salinity and a drop in water temperature. These changes will affect the activity and distribution of fish, so fishermen will adjust their fishing strategies or suspend fishing activities.

[0071] Step S42: Set a time period, collect the climate data within the time period of the estuary area, and statistically analyze the different climate quantities according to the climate data.

[0072] The distribution of the climate is also different within different time periods. For example, summer is the hottest season in the estuary area and also the period with the most rainfall. At this time, the temperature is high, the humidity is high, the rainfall is concentrated, and sometimes it may be affected by typhoons. Therefore, the climate is different within different time periods, and selecting the time period to be evaluated will be more accurate.

[0073] Step S43: Look up the amount of human activities corresponding to the climate according to the climate-human activity quantity table, and multiply it by the corresponding climate quantity to obtain the total amount of human activities corresponding to different climates within the time period.

[0074] For example, on sunny days, the average human activity level in the estuary area is 30 people per square kilometer, and on rainy days, the average human activity level is 5 people per square kilometer. Set the time period from February to March, with more sunny days. The average number of sunny days is 50 days, and the number of rainy days is 10 days. Then the total human activity on sunny days is 30×50 = 150, and the total human activity on rainy days is 5×10 = 50.

[0075] Step S44: Add up the total human activities of all climates and estimate the human activity level in the estuary area.

[0076] In practical applications, adding up the total human activities under all climates can estimate the human activity level during this time period. For example, if there are only sunny days and rainy days during the time period, then add up the total human activities on sunny days and rainy days, 150 + 50 = 200. Estimating the human activity level is beneficial for estimating the degree of damage to the ecological environment of the estuary area by humans based on the human activity level, and thus evaluating the impact on ecological sensitivity.

[0077] The steps to obtain human activity data and evaluate the environmental protection awareness of humans in the estuary area based on the human activity data are specifically as follows: Step S51: Collect the environmental protection publicity information in the estuary area, and extract the environmental protection publicity coverage area and the environmental protection publicity duration based on the environmental protection publicity information.

[0078] Obtain the publicity points of the environmental protection publicity information, determine the environmental protection publicity coverage area based on the publicity points, and count the environmental protection publicity duration. It can be obtained by users uploading environmental protection information or by collecting public environmental protection information afterwards.

[0079] Step S52: Obtain the environmental protection publicity degree based on the environmental protection publicity coverage area and the environmental protection publicity duration.

[0080] Set the weight ratios of the environmental protection publicity coverage area and the environmental protection publicity duration respectively, and calculate the environmental protection publicity degree based on the weight ratios. The larger the environmental protection publicity coverage area and the longer the environmental protection publicity duration, the greater the degree of environmental protection publicity, that is, the greater the environmental protection publicity degree.

[0081] Step S53: Obtain the activity rules in the estuary area, count the compliance rate of humans in the estuary area with the activity rules, and combine with the environmental protection publicity degree to obtain the environmental protection attitude.

[0082] As a special zone where seawater and fresh water meet, human activities in the estuary area are restricted and influenced by various factors. For example, rationally develop and utilize resources such as fisheries, shipping, and water conservancy in the estuary area, set rules for resource utilization, and avoid behaviors such as overfishing and overdevelopment. Statistics on the compliance rate of human activities with the activity rules in the estuary area can reflect the actual environmental protection attitude of humans. Respectively set the proportionality coefficients of the compliance rate and the environmental protection publicity degree, and calculate the environmental protection attitude according to the proportionality coefficients. The larger the compliance rate, the more humans pay attention to environmental protection, and the greater the environmental protection attitude. The greater the environmental protection publicity degree and the better the publicity effect, the more it will also improve the environmental protection attitude of humans.

[0083] Step S54, obtain the development activity information of the estuary area, analyze the importance of the estuary area based on the development activity information, and combine the environmental protection attitude to obtain the environmental protection awareness degree of humans in the estuary area.

[0087] Step S542, obtain the number of people participating in the activities in the estuary area, which is recorded as the activity population, and combine the activity proportion to obtain the importance degree of the estuary area.

[0088] Respectively set the proportionality factors of the activity population and the activity proportion, and calculate the importance degree of the estuary area according to the proportionality factors. The more activities that rely on the estuary area for development and the more people who rely on the estuary area for survival, the more important the estuary area is.

[0089] Step S543, respectively set the proportionality factors of the importance degree of the estuary area and the environmental protection attitude, and calculate the environmental protection awareness degree of humans in the estuary area according to the proportionality factors.

[0090] In practical applications, the greater the environmental protection attitude, the more humans in the estuary area value environmental protection. And the more important the estuary area is to human life, the more humans in the estuary area will pay attention to protecting the estuary area to reduce the impact brought by the estuary area to themselves. Therefore, the environmental protection awareness degree is greater.
