Description

Technical Field

[0001] The present invention relates to the technical field of groundwater pollution detection, and more particularly to a groundwater environment assessment method, system and storage medium for underground space development. Background Art

[0002] Groundwater environment assessment is a key link in underground space development, which involves a systematic analysis of groundwater resources, water quality, flow paths, and potential pollution risks, among which the water pollution risk is the greatest. In existing technologies, a variety of models and methods are used to evaluate the groundwater environment to ensure the sustainability and safety of underground space development. Similar existing technologies include a Chinese patent with the publication number CN117929671A, which proposes a method for predicting and warning the water environment of a basin, including the following steps: S1: constructing a hydrological and hydrodynamic mechanism prediction model of the basin; S2: simulating and predicting the liquid level change of the basin pipe network; S3: constructing a numerical prediction model of the basin; S4: predicting the liquid level change data of the basin pipe network; S5: comparing the results generated by the hydrological and hydrodynamic mechanism prediction model and the numerical prediction model with the actual liquid level change situation respectively, and predicting and warning the risks of waterlogging, overflow and water quality in the basin, realizing the intelligent management of the basin water environment and promoting the multi-objective management of the basin, namely water safety objective, water environment objective and water ecological objective management and refined management. In addition, a similar existing technology is a Dutch patent with the publication number NL2026696A, which provides a method for evaluating the grey water footprint of a basin and a method for formulating a water environment management strategy, including: dividing the basin to be evaluated into evaluation units according to the basic data of the basin; calculating and analyzing the positions of various pollution sources and the inflow pollution load processes in each evaluation unit to obtain the load emissions of various pollution sources; establishing a grey water footprint calculation model for the inflow loads of point sources and non-point sources of sewage in each evaluation unit according to different sewage discharge methods and pollutant migration and reduction equations; determining the calculation parameters of the grey water footprint according to the upstream and downstream relationships of the basin and the distinction of water quality objectives; and calculating various grey water footprint amounts of the evaluation units to be evaluated according to the grey water footprint calculation parameters and the grey water footprint calculation model. It effectively reflects the impact of pollution load on the local water environment emissions at small time and space scales and supports the application of refined and scientific water environment management. The above two patent applications both predict water environmental pollution problems, but the accuracy is insufficient, and at the same time, the problems of different pollution information in different sub-regions and the overlapping problem over time are not considered. Summary of the Invention

[0003] In order to better solve the above problems, the present invention provides a groundwater environment assessment method for underground space development, and the method includes:

[0013] Compare the construction scope in the construction site data corresponding to the construction process in the sub-region with each water system path in the sub-water environment information corresponding to the sub-region. When there is an intersection between the construction scope and any of the water system paths, there is a conflict between the construction site and the water system path in the sub-water environment. The water system path is used as the first water system path. Otherwise, there is no conflict.

[0014] Calculating the first risk score of the conflict path includes:

Simulate the water system characteristics corresponding to the corrected path in the three-dimensional twin model, and compare the water system characteristics of the conflict path with the water system characteristics of the corrected path to obtain a comparison result. Obtain the first risk score according to the comparison result and the first evaluation criterion.

[0016] As a preferred technical solution of the present invention, when there is no conflict between the construction site and the water system path in the corresponding sub-water environment information in the sub-region, use the water system path as the second water system path. Obtain the harmful substance information according to the construction site data. The harmful substance information includes the types, concentrations of harmful substances, and the pollution sources and pollution source locations of the harmful substances. Calculate the shortest distance from the pollution source location to each second water system path corresponding to the second water system path based on the pollution source location and the second water system path. Use the water system corresponding to the second water system path with the shortest distance less than the first set distance as the target water system. Use the water flow velocity and water flow cross-sectional area of each pollution section corresponding to the target water system in the sub-environment data as the target water system information. Input the water flow velocity and water flow cross-sectional area of the pollution section and other sections of the target water system, the concentration of the harmful substance, the distance from the pollution source location to the pollution section of the target water system, and the soil permeability between the pollution source and the pollution section into the pollution prediction sub-model corresponding to the sub-region in the pollution prediction model to obtain the pollution range and pollution degree of the target water system changing with time. Use the pollution range, pollution degree changing with time, and the corresponding time as the pollution information;

[0017] Wherein, the pollution section is the water system path section of the target water system corresponding to the distance between the water system path of the target water system and the pollution source location being less than the second set distance.

[0018] As a preferred technical solution of the present invention, the pollution prediction model includes N pollution prediction sub-models, where N is the number of the sub-regions, and the value range of N is a positive integer greater than or equal to 2.

[0019] As a preferred technical solution of the present invention, obtaining the water environment assessment result of the target development area includes:

When they do not intersect, obtain the second risk score according to all the pollution information in the sub-region and the corresponding second scoring standard. When they intersect and the intersection position is within the sub-region, add the pollution information corresponding to the intersection position in the adjacent sub-region to all the pollution information in the sub-region to obtain the total pollution information, and obtain the second risk score according to the total pollution information and the second scoring standard. Then, use the first risk score and the second risk score corresponding to the sub-region as the sub-risk assessment result corresponding to the sub-region, and use the risk level corresponding to the average value of all the sub-risk assessment results corresponding to all the sub-regions as the water environment assessment result of the target development area.

[0021] As a preferred technical solution of the present invention, after obtaining each pollution information of the sub-region, the pollution information is also displayed in the three-dimensional twin model and presented through an animation.

When there is a conflict, it corrects the conflict path, obtains the corrected path, compares the corrected path with the conflict path, obtains the comparison result, and obtains the first risk score corresponding to the conflict path according to the comparison result and the first evaluation criterion;

[0027] The second evaluation unit is configured to, when there is no conflict between the construction site and the water system path in the sub-region, obtain the harmful substance information during the construction process according to the construction site data, and also obtain the target water system and the target water system information according to the harmful substance information and the sub-water environment information corresponding to the sub-region. According to the target water system information, the harmful substance information, the soil permeability between the polluted section of the target water system and the harmful substance pollution source, and the pollution prediction sub-model corresponding to the sub-region in the pollution prediction model, it predicts the pollution information of the sub-region.

When there is a conflict, a correction path is obtained, so as to ensure the normal progress of construction while minimizing the change of the water environment. The water system characteristics corresponding to the above-mentioned correction path are compared with the water system characteristics corresponding to the above-mentioned conflict path, and the above-mentioned first risk score is obtained according to the above-mentioned comparison result and the first evaluation criterion. When there is no conflict, the above-mentioned harmful substance information is obtained according to the above-mentioned construction site data, and the target water system and the polluted section are obtained by calculating the shortest distance between the pollution source location of the above-mentioned harmful substances in the above-mentioned harmful substance information and each of the above-mentioned second water system paths.

BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 It is a flowchart of the groundwater environment assessment method for underground space development of the present invention;

[0032] Figure 2 It is a structural diagram of the groundwater environment assessment system for underground space development of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] The present invention provides a method for evaluating the groundwater environment for underground space development, as Figure 1 shown, the method comprising:

[0035] Step S1: Obtain geological information and water environment information of a target development area through a data collection unit, and create a three-dimensional twin model of the target development area based on the geological information and the water environment information;

[0036] Specifically, collect the geological information and the water environment information of the target development area through the data collection unit, perform preprocessing on the basis of the geological information and the water environment information, and perform fusion. Also, create the corresponding three-dimensional twin model of the target development area based on the fused geological information and water environment data. Among them, the geological information includes the soil type at each position in the target development area and the permeability corresponding to each soil type, and the water environment information includes the water system distribution in the target development area, the water system path of each water system, the water flow velocity of each water system, and the cross-sectional area at each position. Through the above technical solution, a three-dimensional twin model that can reflect the geological characteristics and water system characteristics of the target development area is obtained, thereby facilitating the provision of a basis for simulating the construction site based on the development drawings.

[0037] Step S2: Divide the three-dimensional twin model into multiple sub-areas, simulate the construction site of each construction process based on the construction process of each sub-area and the three-dimensional twin model, and obtain construction site data;

[0038] Specifically, obtain the construction process through the above development design drawings and development plan, divide the three-dimensional twin model into multiple sub-areas according to the construction area corresponding to the construction process, and also simulate the construction process of the construction process in the corresponding sub-area in the corresponding three-dimensional twin model according to the construction sequence of each construction process, so as to relatively realistically obtain the construction site data. Through the above technical solution, a basis is laid for further calculating the damage risk caused by the construction process to the water environment of the sub-area.

[0039] Step S3: Judge whether there is a conflict between the construction site and the water system path in the sub-area based on the construction scope in the construction site data corresponding to the construction process. When there is a conflict, correct the conflict path to obtain a corrected path, compare the corrected path with the conflict path to obtain a comparison result, and obtain a first risk score corresponding to the conflict path according to the comparison result and the first evaluation criterion;

[0040] Specifically, by comparing the above construction scope in the construction site data corresponding to the above construction process with each water system path in the above sub-water environment data corresponding to the above sub-region, and obtaining the comparison result, it is judged whether there is a conflict between the above construction site and each above water system path according to the above comparison result. When the above comparison result shows that there is an intersection between the above construction scope and the above water system path, there is a conflict between the construction site in the above sub-region and the above water system path, and the above water system path is taken as the first water system path. On the contrary, if there is no conflict, and when there is such a conflict, in order to ensure the smooth progress of the above construction process, it is necessary to dredge the water system section where the above conflict path is located to obtain a corrected path. The water system characteristics corresponding to the above corrected path are also compared with the water system characteristics corresponding to the above conflict path to obtain the difference between the two, that is, the above comparison result. The above water system characteristics include the hydrodynamic field, water level and flow velocity. According to the above difference and the first evaluation criterion, the above first risk score is obtained. Among them, the above first evaluation criterion is a scoring rule for evaluating the degree of change in the hydrodynamic field, water level and flow velocity. Through the above technical solution, the first risk score corresponding to each conflict path in each above sub-region can be obtained, laying a foundation for obtaining the water environment risk score of the above target development area.

[0041] Step S4: When there is no conflict between the construction site data corresponding to the construction process in the sub-region and the water system in the sub-region, the harmful substance information during the construction process is also obtained according to the construction site data. The target water system and target water system information are also obtained according to the harmful substance information and the sub-water environment information corresponding to the sub-region. The pollution information of the sub-region is predicted according to the target water system information, the harmful substance information, the soil permeability between the polluted section of the target water system and the harmful substance pollution source, and the pollution prediction sub-model corresponding to the sub-region in the pollution prediction model.

[0042] Specifically, when the construction site in the above-mentioned sub-region does not conflict with the water system path in the corresponding sub-water environment information, the water system path is used as the second water system path. The harmful substance information is obtained according to the construction site data. By calculating the shortest distance between the pollution source location of the harmful substances in the harmful substance information and each of the second water system paths, and taking the water system corresponding to the second water system path with the shortest distance less than the set distance as the target water system. Also, the water system path section with a distance less than the second set distance between the water system path of the target water system and the pollution source location is taken as the polluted section. The water flow velocity and the cross-sectional area of the water flow corresponding to the polluted section of the target water system are obtained through the sub-water environment information. The soil permeability between the pollution source and the polluted section is obtained through the sub-geological information corresponding to the sub-region. By inputting the water flow velocity and cross-sectional area of the polluted section and other sections, the harmful substance concentration, the distance between the pollution source location and the polluted section, and the soil permeability between the pollution source and the polluted section into the pollution prediction sub-model corresponding to the sub-region in the pollution prediction model, the pollution range and pollution degree caused by the pollution source to the target water system over time are obtained. Through the above technical solution, the pollution range and pollution degree caused by each pollution source in each sub-region to the corresponding target water system over time can be accurately obtained.

[0043] Furthermore, the second risk score of each sub-region is obtained according to all the pollution information of each sub-region and the pollution information of adjacent sub-regions. The water environment risk assessment result of the target development area is obtained according to the first risk score and the second risk score of each sub-region.

[0044] Specifically, due to the problem of different construction processes being carried out simultaneously in multiple sub-regions in the above-mentioned target development area, and due to the confluence of water systems in adjacent sub-regions, it is possible that the pollution ranges in multiple adjacent sub-regions may overlap over time. Therefore, obtain all the pollution information corresponding to all pollution sources in the above-mentioned sub-regions, and determine whether the pollution ranges in the pollution information corresponding to each pollution source in the above-mentioned sub-regions intersect with the pollution ranges in the pollution information corresponding to each pollution source in adjacent sub-regions. When the two do not intersect, obtain the second risk score of the above-mentioned sub-region according to all the pollution information in the above-mentioned sub-region and the above-mentioned second scoring criterion. When they intersect and the intersection position is within the above-mentioned sub-region, add the pollution information at the intersection position to all the pollution information of the above-mentioned sub-region to obtain the total pollution information, and obtain the second risk score corresponding to the above-mentioned sub-region according to the total pollution information and the above-mentioned second scoring criterion. Use the above-mentioned first risk score and the second risk score corresponding to the above-mentioned sub-region as the sub-risk assessment result of the above-mentioned sub-region, and use the risk level of the average value of the sub-risk assessment results in all the above-mentioned sub-regions as the water environment assessment result of the above-mentioned target development area, and obtain the above-mentioned risk level according to the risk level division criterion. Through the above technical solution, it is possible to accurately obtain the risk level of the above-mentioned target development area changing over time, which is convenient for users to take timely measures during construction to prevent pollution deterioration.

[0045] Furthermore, obtaining the construction site data includes:

[0046] Obtain the construction process according to the development design drawings and development plan of the target development area, and divide the three-dimensional twin model corresponding to the target development area into multiple sub-regions based on the construction areas corresponding to the construction process;

[0047] Simulate the construction site in the three-dimensional twin model according to the construction process corresponding to the sub-region within the sub-region, and obtain the construction site data, where the construction site data includes the construction scope and the sub-geological data and sub-water environment data within the construction scope.

[0048] Specifically, the construction process is obtained through the above-mentioned development design drawings and development plan. That is, the above-mentioned development design drawings can obtain the development content of the above-mentioned target development area. Based on the above-mentioned development content and the above-mentioned development plan, the specific above-mentioned construction process is obtained. And according to the above-mentioned construction area corresponding to the above-mentioned construction process, the above-mentioned 3D twin model is divided into multiple above-mentioned sub-areas. Among them, the above-mentioned construction process includes not only sequential execution but also parallel execution. Also, according to the construction sequence of each above-mentioned construction process, the construction process is simulated in the corresponding above-mentioned sub-area within the corresponding above-mentioned 3D twin model, so as to truly obtain the above-mentioned construction site data. Through the above-mentioned technical solution, it lays a foundation for further calculating the damage risk caused by the above-mentioned construction process to the water environment corresponding to the above-mentioned sub-area.

[0049] Furthermore, determining whether there is a conflict between the water system path in the water environment information in the construction site and the sub-area includes:

[0050] Compare the construction scope in the construction site data corresponding to the construction process in the sub-area with each water system path in the sub-water environment information corresponding to the sub-area. When there is an intersection between the construction scope and any of the water system paths, there is a conflict between the construction site and the water system path in the sub-water environment. The water system path is used as the first water system path. Otherwise, there is no conflict;

[0051] Calculating the first risk score of the conflict path includes:

[0052] Based on the intersection of the construction site and each of the first water system paths, obtain the conflict path and the position of the conflict path. Correct the conflict path according to the position of the conflict path and the safety distance to obtain a corrected path. Simulate the water system characteristics corresponding to the corrected path in the 3D twin model, and compare the water system characteristics of the conflict path with the water system characteristics of the corrected path to obtain a comparison result. Obtain the first risk score according to the comparison result and the first evaluation criterion.

[0053] Specifically, by comparing the construction scope in the construction site data corresponding to the above construction procedures with each water system path in the above sub-water environment data corresponding to the above sub-region, and obtaining the comparison result, it is judged whether there is a conflict between the construction site and each above water system path according to the above comparison result. When the comparison result shows that there is an intersection between the construction scope and the water system path, there is a conflict between the construction site in the above sub-region and the water system path, and the above water system path is taken as the first water system path. Otherwise, there is no conflict. When there is such a conflict, in order to ensure the smooth progress of the above construction procedures, it is necessary to dredge the water system section where the above conflict path is located. Therefore, the position of the water system section to be dredged is determined through the position of the above conflict path and the above construction scope. When dredging the water system section where the above conflict path is located, it is necessary to follow the premise of minimally changing the hydrodynamic field, flow velocity and water level of the water system section where the above conflict path is located. A predetermined safety distance also needs to be maintained between the above construction scope and the above correction path to prevent the above construction procedures from polluting the water system section where the correction path is located during the construction process. The water system characteristics corresponding to the above correction path are also compared with the water system characteristics corresponding to the above conflict path to obtain the difference between the two, that is, the above comparison result. The above water system characteristics include the hydrodynamic field, water level and flow velocity. The above first risk score is obtained according to the above difference and the first evaluation criterion. Among them, the above first evaluation criterion is a scoring rule for evaluating the degree of change in the hydrodynamic field, water level and flow velocity. Through the above technical solution, the first risk score corresponding to each conflict path in each above sub-region can be obtained, laying a foundation for obtaining the water environment risk score of the above target development area.

[0054] Further, when there is no conflict between the construction site in the above sub-region and the water system path corresponding to the above sub-water environment information, the above water system path is taken as the second water system path. The harmful substance information is obtained according to the construction site data. The harmful substance information includes the types and concentrations of harmful substances, and the pollution sources and pollution source locations of the harmful substances. Based on the pollution source location and the above second water system path, the shortest distance from the pollution source location to each above second water system path is calculated, and the water system corresponding to the second water system path with the shortest distance less than the first set distance is taken as the target water system. The water flow velocity and water flow cross-sectional area of the pollution section corresponding to each above target water system in the above sub-environment data are taken as the above target water system information. The water flow velocity and water flow cross-sectional area of the pollution section and other sections of the above target water system, the concentration of the above harmful substances, the distance from the pollution source location to the pollution section of the above target water system, and the soil permeability between the pollution source and the pollution section are input into the pollution prediction sub-model corresponding to the above sub-region in the pollution prediction model to obtain the pollution range and pollution degree of the above target water system changing with time, and the pollution range, pollution degree and corresponding time changing with time are taken as the above pollution information.

[0055] Wherein, the polluted section is the water system path section of the target water system corresponding to the section of the water system path of the target water system where the distance between the water system path of the target water system and the position of the pollution source is less than a second set distance.

[0056] Specifically, when the construction site in the above-mentioned sub-region does not conflict with the water system path in the corresponding sub-water environment information, the above-mentioned water system path is used as the second water system path, that is, there is no intersection between the construction scope corresponding to the construction site and the second water system path. Although the second water system path does not conflict with the construction scope, it may be polluted through infiltration. Therefore, the above-mentioned harmful substance information is obtained according to the above-mentioned construction site data, and the shortest distance between the pollution source position of the harmful substances in the above-mentioned harmful substance information and each of the above-mentioned second water system paths is calculated, and the water system corresponding to the second water system path with the shortest distance less than the above-mentioned set distance is used as the above-mentioned target water system, so as to obtain the water system that may be polluted by the above-mentioned harmful substances. The water system path section with a distance less than the second set distance between the water system path of the target water system and the pollution source position is used as the above-mentioned polluted section. The water flow velocity and the cross-sectional area of the water flow corresponding to the above-mentioned polluted section of the target water system are obtained through the above-mentioned sub-water environment information. The product of the water flow velocity and the cross-sectional area of the water flow reflects the water flow volume per unit time of the above-mentioned polluted section. The soil permeability between the pollution source and the above-mentioned polluted section is obtained through the sub-geological information corresponding to the above-mentioned sub-region. The soil permeability, the concentration of the above-mentioned harmful substances, the distance between the pollution source position and the above-mentioned polluted section together determine the infiltration rate of the harmful substances. Therefore, by inputting the water flow velocity and the cross-sectional area of the water flow in the above-mentioned polluted section and other sections, the concentration of the above-mentioned harmful substances, the distance between the pollution source position and the above-mentioned polluted section, and the soil permeability between the pollution source and the above-mentioned polluted section into the pollution prediction sub-model corresponding to the above-mentioned sub-region in the above-mentioned pollution prediction model, the pollution range and pollution degree of the pollution caused by the above-mentioned pollution source to the above-mentioned target water system changing with time are obtained. The pollution degree is the concentration of the harmful substances in the above-mentioned target water system. Wherein, the above-mentioned pollution prediction model is a distributed model, and multiple pollution prediction sub-models in the above-mentioned pollution prediction model can simultaneously predict the pollution situation in the corresponding sub-region. Through the above technical solution, it is possible to accurately obtain the pollution range and pollution degree of each pollution source in each sub-region to the corresponding target water system changing with time.

[0057] Further, the pollution prediction model includes N pollution prediction sub-models, N is the number of the sub-regions, and the value range of N is a positive integer greater than or equal to 2.

[0058] Specifically, the above pollution prediction model is a distributed model. The above pollution prediction model includes N of the above pollution prediction sub-models. The above pollution prediction sub-models are respectively trained through the historical pollution data of the corresponding sub-regions. The above historical pollution data includes historical harmful substances, the polluted sections of each water system in the above sub-region and the water flow velocity and cross-sectional area of other sections, the concentrations corresponding to various of the above harmful substances, the distance between the historical pollution source location and the polluted section of the corresponding water system, the soil permeability between the historical pollution source and the polluted section of the corresponding water system, and the historical pollution range and historical pollution degree of the above water system changing with time. Through the above technical solution, when multiple sub-regions in the above target development area are under construction simultaneously, the pollution conditions of the corresponding sub-regions can be predicted simultaneously through the corresponding pollution prediction sub-models in the above pollution prediction model, so as to facilitate taking corresponding measures in time during construction to prevent the deterioration of pollution.

[0059] Further, obtaining the water environment assessment result of the above target development area includes:

[0060] Obtaining all pollution information corresponding to all pollution sources in the above sub-region, and determining whether the pollution ranges corresponding to each pollution source in the above sub-region and the pollution ranges corresponding to each pollution source in the adjacent sub-region intersect. When they do not intersect, obtaining the second risk score according to the above all pollution information of the sub-region and the corresponding second scoring criterion. When they intersect, when the intersection position is within the above sub-region, adding the pollution information corresponding to the above intersection position in the adjacent sub-region to the all pollution information of the sub-region to obtain the total pollution information, and obtaining the second risk score according to the total pollution information and the second scoring criterion, and taking the above first risk score and the second risk score corresponding to the sub-region as the sub-risk assessment result corresponding to the sub-region, and taking the risk level corresponding to the average value of all the above sub-risk assessment results corresponding to all the above sub-regions as the water environment assessment result of the above target development area.

[0061] Specifically, due to the problem that different construction processes in multiple sub-regions are carried out simultaneously in the above-mentioned target development area, and due to the confluence of water systems in adjacent sub-regions, it is possible that the pollution ranges in multiple adjacent sub-regions may overlap over time. When obtaining the total pollution information of the above-mentioned sub-regions, this situation needs to be considered. Since there is more than one pollution source in each sub-region, all pollution information corresponding to all pollution sources in the above-mentioned sub-regions is obtained, and the pollution range in the pollution information corresponding to each pollution source in the above-mentioned sub-region is compared with the pollution range in the pollution information corresponding to each pollution source in the adjacent sub-regions. Among them, the above-mentioned pollution range changes with time. When the two do not intersect, the second risk score of the above-mentioned sub-region is obtained according to the above-mentioned total pollution information in the above-mentioned sub-region and the above-mentioned second scoring criterion. Among them, the above-mentioned second scoring criterion is a scoring criterion for evaluating the pollution range and pollution degree of the above-mentioned sub-region. When they intersect and the intersection position is in the above-mentioned sub-region, that is, the sewage in the adjacent sub-region flows into the above-mentioned sub-region, the pollution information at the intersection position, that is, the intersection range, pollution concentration and intersection time, is added to the total pollution information of the above-mentioned sub-region to obtain the total pollution information, and the second risk score corresponding to the above-mentioned sub-region is obtained according to the above-mentioned total pollution information and the above-mentioned second scoring criterion. The above-mentioned first risk score and the above-mentioned second risk score corresponding to the above-mentioned sub-region are used as the sub-risk assessment result of the above-mentioned sub-region, and the risk level of the average value of the sub-risk assessment results in all the above-mentioned sub-regions is used as the water environment assessment result of the above-mentioned target development area. Among them, the average value of the above-mentioned sub-risk assessment results is the average value of the first risk score and the average value of the second risk score, and the above-mentioned risk level is obtained according to the risk level division standard. The above-mentioned risk level division standard can be defined according to user needs. Through the above technical solution, the risk level of the above-mentioned target development area changing with time and the first risk score and the above-mentioned second risk score of each sub-region changing with time can be accurately obtained, which is convenient for users to take timely measures to prevent pollution deterioration during construction.

[0062] Further, after obtaining each pollution information of the sub-region, the pollution information is also displayed in the three-dimensional twin model and displayed through an animation.

[0063] Specifically, through the above technical solution, the pollution range and pollution degree changing with time in the above-mentioned sub-region can be intuitively displayed.

By comparing the construction scope in the construction site data with each water system path in the sub-water environment data corresponding to the sub-area, it is determined whether there is a conflict between the above-mentioned construction site and the above-mentioned water system path. When there is a conflict, a correction path is obtained, so as to ensure the normal progress of construction while minimally changing the water environment. The water system characteristics corresponding to the above-mentioned correction path are compared with the water system characteristics corresponding to the above-mentioned conflict path, and the above-mentioned first risk score is obtained according to the above-mentioned comparison result and the first evaluation criterion. When there is no conflict, the above-mentioned harmful substance information is obtained according to the above-mentioned construction site data. The target water system and the polluted section are obtained by calculating the shortest distance between the pollution source location of the above-mentioned harmful substances in the above-mentioned harmful substance information and each of the above-mentioned second water system paths. By inputting the water flow velocity, cross-sectional area, the above-mentioned harmful substance concentration, the distance between the pollution source location and the above-mentioned polluted section, and the soil permeability between the pollution source and the above-mentioned polluted section in the above-mentioned polluted section and other sections into the pollution prediction sub-model corresponding to the above-mentioned sub-area in the above-mentioned pollution prediction model, the pollution range and pollution degree of the above-mentioned pollution source to the above-mentioned target water system changing with time are obtained, so as to accurately obtain the pollution range and pollution degree of each pollution source in each sub-area to the corresponding target water system changing with time. The second risk score of each sub-area is also obtained according to all the pollution information of each sub-area and the pollution information of adjacent sub-areas. The water environment risk assessment result of the above-mentioned target development area is obtained according to the above-mentioned first risk score and the second risk score of each sub-area. Through the mutual cooperation of the above-mentioned technical solutions, the water environment risk assessment result of the target development area can be accurately obtained, so as to provide a warning message to the user and timely control to prevent pollution deterioration.
