Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and particularly relates to a groundwater environmental quality data management method, system and medium based on a hierarchical evaluation model. Background Art

[0002] With the rapid development of industrialization and urbanization, the impact of human activities on the groundwater environment has become increasingly significant and complex. Wastewater discharged during industrial production, infiltration of urban domestic sewage, leaching of agricultural fertilizers and pesticides, as well as the decline in water level and spread of pollution caused by overexploitation of groundwater, all make the groundwater environment under unprecedented pressure. These human activities, combined with the influence of natural factors such as geological structure, hydrological cycle and climate change, jointly lead to the increasingly deteriorating groundwater quality. As the main drinking water source for residents in many areas, the deterioration of groundwater quality directly threatens the drinking water safety and physical health of residents. At the same time, groundwater is also an important part of the ecosystem, and its pollution will disrupt the ecological balance, affect biodiversity and the service functions of the ecosystem.

[0003] However, the traditional groundwater environmental quality data management methods have obvious limitations. These methods often rely on the data of monitoring stations and are difficult to comprehensively reflect the situation of the entire groundwater environment area. Unreasonable layout of monitoring stations will lead to data missing or insufficient representativeness in some areas; in addition, due to the dynamic nature of the groundwater environment, the monitoring data at a single time point is difficult to accurately reflect its long-term change trend, lacking systematicness and comprehensiveness in forming the groundwater environmental quality sequence and formulating treatment strategies, resulting in poor treatment effects. These problems make the traditional groundwater environmental quality management methods unable to meet the current complex and changeable environmental requirements. Summary of the Invention

[0047] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0048] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0049] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, the terms "first", "second", etc. are only used for descriptive distinction and cannot be construed as indicating or implying relative importance.

[0050] As Figure 1 shown, a groundwater environmental quality data management method based on a hierarchical evaluation model is provided, including:

[0051] S1. Obtain the groundwater environment area and divide the groundwater environment area into multiple sub - areas to be monitored;

[0052] S2. Obtain the environmental quality data of each sub - area to be monitored, and obtain the water quality factors of each sub - area to be monitored based on the hierarchical evaluation model and the environmental quality data of each sub - area to be monitored;

[0053] S3. Obtain the area of the circulation area used for intercommunication with adjacent sub-areas to be monitored in each sub-area to be monitored, and obtain the contribution degree of each sub-area to be monitored based on the hierarchical evaluation model and the area of the circulation area;

[0054] S4. Obtain the comprehensive water quality index of each sub-area to be monitored based on the hierarchical evaluation model, the water quality factors of each sub-area to be monitored, and the contribution degree of each sub-area to be monitored. Arrange multiple sub-areas to be monitored in descending order according to the comprehensive water quality index to form a groundwater environmental quality sequence, and obtain the treatment strategy for the groundwater environmental area according to the groundwater environmental quality sequence.

[0055] In this embodiment, it should be noted that in S1, the scope of the groundwater environmental area is determined and reasonably divided into multiple sub-areas to be monitored. Specifically, first, obtaining the groundwater environmental area means clarifying the geographical scope of the research, which usually includes information such as the direction of groundwater flow, recharge area, discharge area, and possible pollutant source locations. This step requires the use of means such as geological exploration and hydrogeological surveys to obtain detailed groundwater environmental data.

[0056] After determining the groundwater environmental area, the next step is to divide it into multiple sub-areas to be monitored. The purpose of this division is to manage the groundwater environment more precisely and improve the representativeness and accuracy of monitoring data. When dividing the sub-areas to be monitored, multiple factors need to be considered comprehensively, such as groundwater flow characteristics, geological structure, and pollutant source distribution. For example, in areas with intensive pollutant sources or fast groundwater flow velocity, smaller sub-areas to be monitored can be divided to more accurately capture water quality changes. In relatively homogeneous or slow-flowing areas, the scope of the sub-areas to be monitored can be appropriately expanded. Through such division, it can be ensured that each sub-area to be monitored can reflect different characteristics of the groundwater environment, providing strong support for subsequent environmental quality assessment.

[0057] In S2, when obtaining the environmental quality data of each sub-area to be monitored, multiple monitoring means and technologies need to be relied on, including but not limited to groundwater sampling and analysis, on-line monitoring equipment, remote sensing monitoring, etc. These data should cover various physical, chemical, and biological indicators in groundwater, such as temperature, pH value, dissolved oxygen, heavy metal content, and organic pollutant concentration. The data collection should follow scientific methods and strict quality control standards to ensure the accuracy and reliability of the data.

[0058] After collecting environmental quality data, the next step is to analyze and process these data based on a hierarchical evaluation model. The hierarchical evaluation model here is a tool that can evaluate the groundwater quality according to environmental quality data. By inputting different environmental quality types in the environmental quality data of each sub-region to be monitored into the model, the water quality factors of each sub-region can be calculated to reflect the groundwater environmental quality status of each sub-region to be monitored.

[0059] In S3, when obtaining the circulation area of each sub-region to be monitored, means such as hydrogeological surveys and groundwater flow simulations are needed. These technologies can help us understand the flow paths, velocities, and flows of groundwater between sub-regions, so as to determine which areas are the main channels of groundwater flow and which areas are the key areas of water quality exchange. The size of the circulation area is directly related to the potential and rate of water quality exchange between sub-regions, so it is an important basis for evaluating the contribution degree.

[0060] After obtaining the circulation area, the next step is to calculate the contribution degree of each sub-region to be monitored based on the hierarchical evaluation model and these data. The contribution degree here refers to the degree of influence of the water quality status of a sub-region on the water quality of its adjacent sub-regions and even the entire groundwater environmental region. A sub-region with a high contribution degree means that its water quality change has a greater impact on the entire groundwater environmental region, so more attention needs to be paid when formulating treatment strategies.

[0061] In S4, first, use the hierarchical evaluation model, water quality factors, and contribution degree to calculate the comprehensive water quality index of each sub-region to be monitored. The comprehensive water quality index is a quantitative index that comprehensively considers multiple water quality factors and the impact of water quality exchange between regions. It can comprehensively reflect the water quality status of each sub-region and its contribution to the overall water quality. Specifically, the hierarchical evaluation model will perform a product calculation based on the water quality factors and contribution degree to obtain the comprehensive score of each sub-region. This score not only considers the water quality status of the sub-region itself but also the impact of its water quality change on adjacent regions and even the entire groundwater environmental region. Next, sort multiple sub-regions to be monitored according to the comprehensive water quality index to form a groundwater environmental quality sequence. This sequence can intuitively show the quality of the water in each sub-region and the degree of its impact on the water quality of the entire groundwater environmental region. Based on this sequence, we can formulate more scientific and reasonable treatment strategies. For example, for sub-regions with a higher comprehensive water quality index, more stringent pollution control measures need to be taken to prevent further deterioration of water quality; while for sub-regions with a lower comprehensive water quality index, the control requirements can be appropriately relaxed, and more resources can be invested in regions with worse water quality.

[0062] In summary, in the entire groundwater environmental quality data management method based on the hierarchical evaluation model, by reasonably dividing the groundwater environment area into multiple sub-areas to be monitored, the representativeness and comprehensiveness of the monitoring data are ensured, effectively solving the problems of data loss or insufficient representativeness caused by unreasonable layout of monitoring stations in traditional methods; further, multiple monitoring means and technologies are used to obtain environmental quality data, and water quality factors are calculated based on the hierarchical evaluation model, which can more accurately reflect the groundwater environmental quality status of each sub-area and improve the accuracy and reliability of the data; further, by calculating the contribution degree of each sub-area, the impact of water quality exchange between sub-areas is quantified, providing an important basis for evaluating the spread range and potential risks of regional water quality changes; further, the calculation of comprehensive water quality indicators and the formation of groundwater environmental quality sequences make the formulation of governance strategies more scientific and reasonable, enabling priority attention to areas with poor water quality and greater impact on the overall water quality, optimizing resource allocation, and improving the governance effect; in summary, it not only overcomes the limitations of traditional groundwater environmental quality data management methods, but also provides strong technical support for the protection and governance of the groundwater environment through comprehensive evaluation and management, meeting the current complex and changing environmental needs.

[0063] In one embodiment, in S2, the hierarchical evaluation model for obtaining the water quality factors of each sub-area to be monitored based on the hierarchical evaluation model and the environmental quality data of each sub-area to be monitored includes:

[0064] Among them,

[0065] Y i is the water quality factor of the i-th sub-area to be monitored, and α j is the adjustment coefficient of the j-th environmental quality type, x ij is the value of the j-th environmental quality type in the environmental quality data of the i-th sub-area to be monitored, x jmin is the minimum value of the j-th environmental quality type, x jmax is the maximum value of the j-th environmental quality type, and m is the number of environmental quality types in the environmental quality data.

[0066] In this embodiment, it should be noted that α j is the adjustment coefficient of the j-th environmental quality type, which represents the importance of this environmental quality type in the overall evaluation. By adjusting this coefficient, different weights can be assigned to different environmental quality types according to the actual situation, so as to more accurately reflect the actual situation of the groundwater environment. x ij is the value of the j-th environmental quality type in the environmental quality data of the i-th sub-area to be monitored, which is the original monitoring data and directly reflects the specific performance of this sub-area in the j-th environmental quality type. x jmin and x jmaxare the minimum and maximum values of the j-th environmental quality type, which are obtained from experts in the field or relevant materials and are used to normalize the data so that data of different environmental quality types are comparable. m is the number of environmental quality types in the environmental quality data, indicating how many environmental quality types are considered in the evaluation process.

[0067] In summary, through the method of weighted summation, the impacts of various environmental quality types on water quality are comprehensively considered, avoiding the one-sidedness of single-index evaluation and making the calculation of water quality factors more comprehensive and accurate. Further, by adjusting the coefficient α j , the weights of different environmental quality types in the overall evaluation can be adjusted according to actual situations, making the evaluation model more flexible and capable of adapting to the characteristics and requirements of different groundwater environments. Further, by using x jmin and x jmax for normalization processing, the dimensional differences between data of different environmental quality types are eliminated, enabling them to be compared and calculated on the same scale, and improving the accuracy and comparability of the evaluation.

[0068] In one embodiment, the hierarchical evaluation model in S3 for obtaining the contribution degree of each sub-region to be monitored based on the hierarchical evaluation model and the circulation area includes:

[0069] C i =βln(A i +1); where,

[0070] C i is the contribution degree of the i-th sub-region to be monitored, A i is the circulation area of the i-th sub-region to be monitored, and β is the contribution degree adjustment coefficient.

[0071] In this embodiment, it should be noted that C i represents the contribution degree of the i-th sub-region to be monitored, which reflects the impact degree of the water quality status of this sub-region on the water quality of its adjacent sub-regions and even the entire groundwater environment region. A i is the circulation area of the i-th sub-region to be monitored, which represents the flow and exchange ability of groundwater in this sub-region. The larger the circulation area, the more likely the water quality change in this sub-region is to affect other regions, so its contribution degree is correspondingly higher. β is the contribution degree adjustment coefficient, which is used to adjust the calculation result of the contribution degree to ensure that the model can adapt to different groundwater environment characteristics and monitoring requirements. Using ln(A iCalculating the contribution degree in the form of [[ID=]], can well describe the non-linear relationship between the area of the circulation area and the contribution degree. In actual situations, the increase in the area of the circulation area does not lead to a linear increase in the contribution degree, but will gradually tend to saturation. The logarithmic function can well simulate this change trend, making the calculation of the contribution degree more in line with the actual situation; further, in A i it grows faster when it is smaller, and in A i it grows slower when it is larger. This characteristic enables the contribution degree to increase rapidly when the area of the circulation area is small, and the growth tends to be gentle when the area is large. Such a setting can avoid drastic fluctuations in the contribution degree due to small changes in the area of the circulation area, making the model more stable and reliable; further, adding "+1" is to consider the special case where the area of the circulation area is zero, that is, when A i =0, so that the situation where the area of the circulation area is zero can be reasonably handled, avoiding errors in the model; finally, by adjusting the adjustment coefficient β, the calculation result of the contribution degree can be flexibly controlled. Under different groundwater environment characteristics and monitoring requirements, the value of β can be adjusted to make the model more adaptable to the actual situation and improve the accuracy and applicability of the model.

[0072] In one embodiment, the hierarchical evaluation model in obtaining the comprehensive water quality index of each sub-region to be monitored based on the hierarchical evaluation model, the water quality factors of each sub-region to be monitored, and the contribution degree of each sub-region to be monitored includes:

[0073] I i =γC i ·Y i ; where,

[0074] I i is the comprehensive water quality index of the i-th sub-region to be monitored, and γ is the water quality index adjustment coefficient.

[0075] In this embodiment, it should be noted that I i represents the comprehensive water quality index of the i-th sub-region to be monitored, which comprehensively reflects the water quality status of this sub-region and its impact on the overall water quality. C i is the contribution degree of the i-th sub-region to be monitored, which represents the impact degree of the water quality status of this sub-region on the water quality of its adjacent sub-regions and even the entire groundwater environment region. The greater the contribution degree, the greater the impact of the water quality change in this sub-region on the overall water quality. Y iis the water quality factor of the i-th sub-region to be monitored. It synthesizes data of multiple environmental quality types and is used to reflect the overall water quality status of the sub-region. Generally speaking, the larger the water quality factor, the worse the water quality status of the sub-region. γ is the water quality index adjustment coefficient, which is used to adjust the calculation result of the comprehensive water quality index to ensure that the model can adapt to different groundwater environmental characteristics and monitoring requirements. By adjusting the value of γ, the calculation of the comprehensive water quality index can be made more in line with the actual situation, improving the accuracy and applicability of the model. The comprehensive water quality index I i simultaneously considers the water quality factor Y i and the contribution degree C i These two factors make the evaluation more comprehensive and accurate. By analyzing parameters such as water flow velocity and flow rate, it is possible to determine which areas are the main channels of groundwater flow, and then calculate the area of these channels as the area of the circulation region. For example, if the simulation results show that the water flow velocity and flow rate in a certain area are relatively fast and large, then this area may be identified as the circulation region, and its area will be calculated accordingly.

[0076] Such as Figure 2 shown, in one embodiment, obtaining the area of the circulation region for each sub-region to be monitored for intercommunication with adjacent sub-regions in S3 includes:

[0077] S31. Determine the boundary positions of the sub-regions to be monitored;

[0078] S32. Simulate the flow conditions at the boundary positions;

[0079] S33. Obtain the area of the circulation region according to the flow conditions.

[0080] In this embodiment, it should be noted that in S31, through means such as geological exploration and hydrological investigation, the specific boundary positions of each sub-region to be monitored need to be clarified. These boundaries may be jointly determined by various factors such as geological structure, topography, and hydrological conditions. After determining the boundary positions, the intercommunication situation between this sub-region and adjacent sub-regions can be further analyzed.

[0081] In S32, after determining the boundary positions of the sub-regions to be monitored, it is necessary to simulate the flow conditions of groundwater at the boundary positions. This usually involves the establishment and solution of a groundwater dynamics model, including the calculation of parameters such as water flow velocity, direction, and flow rate. By simulating the flow conditions, the exchange and flow characteristics of groundwater between different sub-regions can be understood, providing a basis for calculating the area of the circulation region in the follow-up.

[0082] In S33, by analyzing parameters such as water flow velocity and flow rate, it is possible to determine which areas are the main channels of groundwater flow, and then calculate the area of these channels as the area of the flow-through region. For example, if the simulation results show that the water flow velocity and flow rate in a certain area are relatively high, then this area may be identified as the flow-through region, and its area will be calculated accordingly.

[0083] As Figure 3 shown, in one embodiment, in S1, dividing the groundwater environment area into multiple sub-areas to be monitored includes:

[0084] S11. Set a segmentation window according to the distribution of the groundwater environment area;

[0085] S12. Divide the groundwater environment area into multiple sub-areas to be monitored according to the segmentation window.

[0086] In this embodiment, it should be noted that in S11, a segmentation window is set according to the distribution of the groundwater environment area. In actual operation, various factors such as the geological structure, hydrogeological conditions, and pollution status of the groundwater environment area need to be comprehensively considered to determine a suitable segmentation window. The segmentation window can be a fixed size or can be dynamically adjusted according to the characteristics of the groundwater environment area. For example, in an area with complex geological structure and large changes in hydrogeological conditions, a smaller segmentation window may need to be set to more accurately reflect the changes in the groundwater environment.

[0087] In S12, according to the size and shape of the window, the groundwater environment area is divided into multiple sub-areas to be monitored. These sub-areas should be able to comprehensively cover the entire groundwater environment area, and there should be clear boundaries between each sub-area. The divided sub-areas to be monitored can be used as the basic units for subsequent monitoring and analysis. By monitoring and analyzing parameters such as water quality and flow rate of each sub-area, the status of the groundwater environment area can be comprehensively understood.

[0088] For example, assume that a certain groundwater environment area is a complex irregular area. A suitable segmentation window can be set according to the horizontal and vertical dimensions of this area. For example, take the distance from the leftmost side to the rightmost side of this area as the length, and the distance from the uppermost side to the lowermost side of this area as the width. Then, a reduced and refined segmentation window is divided according to the length and width, and the entire groundwater environment area is divided into multiple sub-areas to be monitored using this segmentation window. In this way, each sub-area can be used as an independent monitoring unit, facilitating subsequent water quality monitoring and data analysis work.

[0089] As Figure 4 shown, in one embodiment, it further includes:

[0090] S5. Obtain the historical environmental quality data of the groundwater environment area, form a historical groundwater environment quality sequence based on the historical environmental quality data, and obtain the treatment strategy for the groundwater environment area according to the historical groundwater environment quality sequence and the groundwater environment quality sequence.

[0091] In this embodiment, it should be noted that in S5, first, it is necessary to collect the historical environmental quality data of the groundwater environment area. Then, based on the collected historical environmental quality data, a historical groundwater environment quality sequence can be formed. Among them, in one case, the historical environmental quality data may directly include the previous groundwater environment quality sequence formed by this technical solution, that is, the historical groundwater environment quality sequence, so it can be directly used. In another case, the historical environmental quality data only includes the historical environmental quality data and the area of the circulation area, so it is necessary to recalculate the historical water quality factors and historical contribution degrees to form the historical groundwater environment quality sequence.

[0092] Finally, by combining the current groundwater environment quality sequence (i.e., the data obtained through real-time monitoring), the historical data can be compared to evaluate the effect of the treatment measures, and the treatment strategy can be adjusted or a new one can be formulated according to the actual situation. For example, if it is found that the pollutant concentration in a certain area continues to rise and exceeds the safety standard, then targeted treatment measures need to be formulated, such as strengthening the control of pollution sources, increasing the frequency of groundwater monitoring, and carrying out pollution treatment projects. By continuously comparing the historical data and the real-time monitoring data, the treatment strategy can be dynamically adjusted to ensure the continuous improvement of the groundwater environment quality.

[0093] A groundwater environment quality data management system based on a hierarchical evaluation model is also provided. The system includes:

[0094] An acquisition module for acquiring the groundwater environment area and dividing the groundwater environment area into multiple sub-areas to be monitored;

[0095] A first acquisition and calculation module for acquiring the environmental quality data of each sub-area to be monitored and obtaining the water quality factors of each sub-area to be monitored based on the hierarchical evaluation model and the environmental quality data of each sub-area to be monitored;

[0096] A second acquisition and calculation module for acquiring the area of the circulation area used for intercommunication with adjacent sub-areas to be monitored in each sub-area to be monitored and obtaining the contribution degree of each sub-area to be monitored based on the hierarchical evaluation model and the area of the circulation area;

[0097] The calculation, arrangement, and management module obtains the comprehensive water quality indicators of each sub-region to be monitored based on the hierarchical evaluation model, the water quality factors of each sub-region to be monitored, and the contribution degrees of each sub-region to be monitored, arranges multiple sub-regions to be monitored in descending order according to the comprehensive water quality indicators in sequence to form a groundwater environmental quality sequence, and obtains the treatment strategy for the groundwater environmental region according to the groundwater environmental quality sequence.

[0098] In this embodiment, it should be noted that for the above groundwater environmental quality data management system based on the hierarchical evaluation model, the specific manner of performing operations has been described in detail in the embodiment of the groundwater environmental quality data management method based on the hierarchical evaluation model, and will not be elaborated here.
