[0014] In an optional implementation, the risk assessment module includes: an acquisition unit and an assessment unit;

[0015] The acquisition unit is used to obtain the water ecological area to be evaluated and the ecological environment element set and the comprehensive overview information set of the water ecological area to be evaluated, and send the ecological environment element set and the comprehensive overview information set to the evaluation unit. The comprehensive overview information set is used to reflect the natural, ecological and social conditions of the water ecological area to be evaluated; the evaluation unit is used to conduct risk assessment on the water ecological area to be evaluated based on the ecological environment element set and the comprehensive overview information set to obtain the risk assessment results.

[0016] The water ecological risk management system provided by the present invention can comprehensively collect the ecological environment element set and comprehensive profile information set of the water ecological area to be evaluated through the acquisition unit, covering the natural, ecological and social conditions, and providing rich and comprehensive data support for subsequent risk assessment. Furthermore, in the assessment unit, based on the multi-source information obtained, a scientific risk assessment of the water ecological area is carried out and various data are integrated to obtain the risk assessment results, so that the assessment process is based on sufficient data and reasonable analysis methods, which improves the scientificity and credibility of the assessment.

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0040] The embodiment of the present invention provides a water ecological risk management system, which manages the risk assessment results by utilizing a risk management module so that users can timely understand the specific conditions of the area, ensure the life safety of users, and avoid economic losses of users to a certain extent.

[0041] In this embodiment, a water ecological risk management system is provided. Figure 1 As shown, the water ecological risk management system 1 includes: a risk assessment module 11, a risk warning module 12 and a risk management module 13.

[0042] The risk management module 13 includes a map 131 , a hiding unit 132 , an enlarged display unit 133 and a management unit 134 .

[0043] Optionally, the risk assessment module 11 is used to perform risk assessment on the water ecological area to be assessed, obtain risk assessment results, and send the risk assessment results to the risk warning module 12.

[0044] The risk assessment module 11 includes an acquisition unit 111 and an assessment unit 112 .

[0045] Furthermore, the water ecological area to be assessed represents a specific geographical area whose ecological environmental risk status needs to be analyzed, judged and assessed in the water ecological risk management system.

[0046] In this embodiment, the water ecological area to be evaluated can be obtained in the following manner: based on the area to be monitored, the river basins in the area are divided, and a river basin is easily selected as the water ecological area to be evaluated.

[0047] Specifically, the acquisition unit 111 can be used to acquire the water ecological region to be evaluated and the ecological environment element set and the comprehensive overview information set of the water ecological region to be evaluated, and send the ecological environment element set and the comprehensive overview information set to the evaluation unit 112.

[0048] Among them, the ecological environment element set is used to describe and reflect the ecological environment status of the water ecological area to be evaluated, and may include the vegetation coverage on both sides of the water ecological area to be evaluated, riverbed depth, landform conditions, etc.

[0049] Specifically, the vegetation coverage on both sides of the river can be obtained through remote sensing image analysis, field sampling survey methods, etc.; the riverbed depth can be obtained through acoustic detection technology, etc.; the landform conditions can be obtained through topographic measurement and landform mapping, geographic information system, etc.

[0050] Furthermore, the comprehensive overview information set is used to reflect the natural, ecological and social conditions of the water ecological region to be evaluated, and may include weather conditions, basic conditions of regional rivers and basic social conditions of the water ecological region to be evaluated.

[0051] Specifically, weather conditions can be obtained through meteorological stations, meteorological models, etc.; basic conditions of regional rivers can be obtained through river hydrological monitoring, river morphology and structure investigation, etc.; basic social conditions can be obtained through government departments (such as the Statistics Bureau, Environmental Protection Bureau, Water Resources Bureau, etc.), field visits and questionnaires, etc.

[0052] Furthermore, the assessment unit 112 may perform risk assessment on the water ecological area to be assessed according to the received ecological environment element set and comprehensive overview information set to obtain a risk assessment result.

[0053] Specifically, based on the obtained ecological environment element set and comprehensive overview information set, risk assessment can be performed simultaneously from two different dimensions: ecological environment and comprehensive overview, fully considering the relationship between the water ecosystem and the natural environment and social environment, and more comprehensively grasping the risk status faced by the water ecological area, avoiding only evaluating from a single perspective and ignoring other important risk factors, thereby improving the scientificity and credibility of the assessment. Further, the risk assessment results can be sent to the risk warning module 12.

[0054] In an optional implementation, firstly, the various data in the ecological environment element set and the comprehensive overview information set are normalized. Further, the principal component analysis method is used to reduce the dimension of the data, which can retain the information of the original data to the greatest extent, while reducing the data dimension and reducing the computational complexity.

[0055] Secondly, the data after preprocessing and feature extraction is used as input to construct a random forest model. In the process of model training, the random forest generates multiple different training subsets by sampling the training data with replacement, and each subset is used to train a decision tree. During the construction of the decision tree, the optimal features are selected for node splitting based on criteria such as information gain and Gini index, so as to classify or regress the data. For water ecological risk assessment, the random forest model can divide water ecological areas into different risk levels based on ecological environmental factors and comprehensive overview information.

[0056] Furthermore, grid search or random search methods are used to optimize the model parameters and select the parameter combination with the best performance to construct the final risk assessment model.

[0057] Finally, the optimized random forest model is used to predict the input set of ecological and environmental elements and the comprehensive profile information set. Specifically, the optimized random forest model can judge the risk level of the water ecological area to be assessed based on the relationship between the features and risk levels learned during the training process. For example, the model output may be a discrete risk level category such as high risk, medium risk, low risk or no risk.

[0058] Optionally, the risk warning module 12 is used to determine multiple display colors based on the risk assessment result, and control the multiple display colors to be displayed in the map 131.

[0059] Among them, multiple display colors are used to characterize the risk situation of the water ecological area to be assessed.

[0060] Furthermore, the risk warning module 12 includes a processing unit 121 and an inserting unit 122 .

[0061] Optionally, the processing unit 121 divides the risk situation of the water ecological area to be assessed into colors based on the risk assessment result, obtains multiple display colors, and sends the multiple display colors to the insertion unit 122.

[0062] Specifically, the processing unit 121 may determine the risk level to which the area belongs according to the received risk assessment result.

[0063] Furthermore, the risk situation of the water ecological area to be assessed can be divided into colors according to the pre-set risk level and color correspondence rules. For example, the rule can be set to correspond to red for high risk, yellow for medium risk, and green for low risk.

[0064] Furthermore, the multiple display colors obtained by division may be sent to the inserting unit 122 .

[0065] Optionally, the inserting unit 122 is used to manage multiple display colors with the map so that the multiple display colors are displayed in the map.

[0066] Specifically, after receiving the multiple display colors, the inserting unit 122 can accurately locate the area on the map through the geographical coordinates or boundary information of the area.

[0067] Furthermore, each display color may be associated with a corresponding water ecological region on the map.

[0068] Furthermore, through mapping technology, colors representing different risk levels are filled into corresponding areas on the map, so that multiple display colors are displayed in the map, so that users can intuitively obtain risk situation information of water ecological areas from the map.

[0069] Optionally, the hiding unit 132 is used to control the hiding of multiple display colors when the map 131 is not in use.

[0070] Specifically, the hiding unit 132 may continuously monitor the usage status of the map 131 .

[0071] For example, the hiding unit 132 may obtain information in real time about whether the map is being operated or viewed by the user through interaction with the map display system.

[0072] Furthermore, when the hiding unit 132 detects that the map 131 is not in use, it controls multiple display colors in the map 131 to be hidden, that is, when the map 131 is not in use, the user will not see the risk color information displayed on the map, thereby ensuring the simplicity of the map interface in non-essential situations and avoiding information interference.

[0073] Optionally, the magnification display unit 133 is used to distinguish multiple display colors of the target area when the target area in the map 131 is magnified, and send the distinction result to the management unit 134.

[0074] Specifically, when the user zooms in on a target area in the map 131 by zooming in or out with a mouse wheel or by pinching the screen, the zoom display unit 133 can make a detailed distinction between multiple display colors in the target area.

[0075] Exemplarily, the magnifying display unit 133 first determines the coordinate range of the target area on the map, and then analyzes the display color distribution corresponding to different risk levels within the range. For example, if there are red (representing high risk), yellow (representing medium risk) and green (representing low risk) areas in the target area, the magnifying display unit 133 can respectively identify the boundaries, shapes and proportions of the different color areas.

[0076] Furthermore, after completing the color distinction, the magnification display unit 133 may organize these detailed distinction results into a specific data format and send it to the management unit 134 .

[0077] Optionally, the management unit 134 is used to provide a text description of the risk situation of each display color of the target area based on the differentiation result, and display the text description content.

[0078] Specifically, after receiving the differentiation results of multiple display colors of the target area, the management unit 134 can provide a text description of the risk situation represented by each display color in the target area according to the received differentiation results and a preset risk level description template.

[0079] The text description may include risk level, risk area location, risk characteristic description, etc.

[0080] Furthermore, after completing the text description, the management unit 134 can display the text content to the user in an appropriate manner. For example, an information window can be popped up on the map interface to display the risk text description of the corresponding target area in the window; or the risk text description content of the target area can be updated in the information bar next to the map. In this way, after the user zooms in on the target area of ​​the map, he can intuitively obtain a detailed text description of the risk situation in the area and further understand the potential risks of the water ecological area.

[0081] Optionally, the risk management module also includes: an analysis unit 135, which is used to receive the text description content sent by the management unit 134, and analyze and process the risk situation of the water ecological area to be assessed according to the text description content to obtain a risk management plan.

[0082] Specifically, after receiving the text description content sent by the management unit 134, the analysis unit 135 can study the risk characteristics, impact scope, degree of harm, etc. based on the received text description content, break down the risk factors and determine the causes of the risk and possible further impacts on the water ecological area.

[0083] Further, according to the results of the risk situation analysis, the analysis unit 135 can formulate corresponding governance plans for different risk factors and natural conditions. Among them, the plan formulation can comprehensively consider multiple factors, including ecological protection principles, cost-effectiveness, operability, etc.

[0084] Furthermore, the analysis unit 135 may also perform risk management on the water ecological area to be assessed according to the risk management plan and determine the management completion time, and update the management completion time to the map 131 .

[0085] Specifically, the analysis unit 135 can also coordinate relevant resources and departments according to the formulated governance plan to govern the risky areas. Furthermore, in the governance process, various governance measures are strictly implemented in accordance with the requirements of the plan to ensure the effectiveness and pertinence of the governance work.

[0086] Furthermore, during the implementation of risk governance, the analysis unit 135 can establish a reasonable time estimation model and combine the actual progress of the governance work, such as the progress, difficulty, and resource input, to accurately determine the time required for governance in the area, that is, the governance completion time.

[0087] Finally, the analysis unit 135 can update the budgeted governance time information to the map 131. Furthermore, in the map 131, the location associated with the risk area will show the approximate completion time of the risk governance, which can not only allow the user to understand the risk status of the current water ecological area, but also know the expected time of risk governance, providing an important reference for users to reasonably arrange activities and plan for the future, and enhancing the comprehensiveness and foresight of the system's water ecological risk management.

[0088] The water ecological risk management system provided in this embodiment can systematically conduct risk assessment on the water ecological area to be assessed through the risk assessment module, avoiding blind assessment. Further, the risk warning module can convert the abstract risk assessment results into intuitive visual colors and display them on the map. Different colors correspond to different risk situations, which greatly improves the readability and recognizability of risk information, allowing users to quickly understand the risk distribution status of the water ecological area. Further, the risk color display is hidden when the map is not in use, avoiding the clutter of information, ensuring the simplicity of the map when it is not necessary, and improving the user experience. When the risk information is really needed, it is displayed, making the information presentation more targeted. Further, when the user is interested in a specific target area and zooms in on the map, the colors of different risk levels in the area can be accurately distinguished, and the risk information display can be further refined, meeting the user's demand for detailed risk information in the local area. Finally, based on the distinction result of the magnified display unit, the risk situation represented by each color is described and displayed in text, and the visual color information is converted into a specific text description, which is convenient for the user to observe, so that the user can understand the specific situation of the area in time, ensuring the user's life safety, and avoiding the user's economic loss to a certain extent.

[0089] According to an embodiment of the present invention, an embodiment of a water ecological risk assessment method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0090] In this embodiment, a water ecological risk assessment method is provided, which can be used for example Figure 1 The risk assessment module 11 shown, Figure 2 is a flow chart of a water ecological risk assessment method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0091] Step S201, obtaining the water ecological region to be evaluated and the ecological environment element set and comprehensive overview information set of the water ecological region to be evaluated.

[0092] Among them, the comprehensive overview information set is used to reflect the natural, ecological and social conditions of the water ecological area to be assessed.

[0093] The specific process may refer to the functional description of the acquisition unit 111 in the risk assessment module 11 in the above embodiment, which will not be repeated here.

[0094] Step S202, based on the ecological environment element set and the comprehensive overview information set, risk assessment is performed on the water ecological area to be assessed to obtain multiple risk assessment results.

[0095] Specifically, risk assessment can be carried out separately according to the set of ecological and environmental elements and the set of comprehensive overview information, and multiple risk assessment results can be obtained, including risk assessment situations corresponding to factors such as soil loosening, vegetation density, rainfall, industrial pollution, other pollution and riverbed changes. This fully considers the relationship between the water ecosystem and the natural environment and social environment, and can more comprehensively grasp the risk situation faced by the water ecological area, avoiding evaluation from a single perspective and ignoring other important risk factors.

[0096] In an optional implementation, risk assessment may be performed on each ecological environment element and comprehensive overview information separately according to the set risk assessment index.

[0097] Step S203, fusing multiple risk assessment results to obtain multiple risk fusion results.

[0098] Specifically, multiple risk determination results may be fused according to a pre-set fusion rule to obtain multiple risk fusion results.

[0099] In an optional implementation, firstly, a suitable fusion method is selected according to the characteristics and requirements of the risk determination results, such as the weighted average method, the evidence theory method, etc.

[0100] Furthermore, the selected fusion method can be used to calculate multiple risk determination results. Taking the weighted average method as an example, each risk determination result is multiplied by its corresponding weight, and then summed to obtain a comprehensive risk value.

[0101] Furthermore, fusion calculations are performed separately for different risk determination dimensions (such as ecological environment dimension, social impact dimension, etc.) to obtain multiple risk fusion results.

[0102] Step S204, using multiple risk fusion results to perform risk assessment on the water ecological area to be assessed, to obtain a risk assessment result of the water ecological area to be assessed.

[0103] Specifically, the multiple risk fusion results obtained can further accurately determine the risk level of the water ecological area to be assessed, thereby improving the accuracy and reliability of risk assessment. Furthermore, accurate risk assessment results can help to rationally allocate resources, improve the efficiency and effectiveness of risk management, and achieve sustainable development of water ecological areas.

[0104] The water ecological risk assessment method provided in this embodiment firstly obtains the ecological environment element set and the comprehensive profile information set, and can collect information on the water ecological area to be assessed from multiple dimensions such as nature, ecology and society, providing a rich data basis for subsequent risk assessment and ensuring the accuracy and reliability of the assessment results. Secondly, risk determination is performed separately according to the ecological environment element set and the comprehensive profile information set, fully considering the relationship between the water ecosystem and the natural environment and the social environment, and can more comprehensively grasp the risk situation faced by the water ecological area, avoiding only evaluating from a single perspective and ignoring other important risk factors. Further, by fusing multiple risk determination results, the interaction and synergistic influence between different factors can be comprehensively considered, thereby improving the accuracy and reliability of the risk assessment results. Finally, based on the fused risk results, the risk level of the water ecological area to be assessed can be accurately determined, which improves the accuracy and reliability of the risk assessment. Furthermore, accurate risk assessment results can help to reasonably allocate resources, improve the efficiency and effectiveness of risk management, and achieve sustainable development of water ecological areas.

[0105] In this embodiment, a water ecological risk assessment method is provided, which can be used for example Figure 1 The risk assessment module 11 shown, Figure 3 is a flow chart of a water ecological risk assessment method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0106] Step S301, obtaining the water ecological region to be evaluated and the ecological environment element set and comprehensive overview information set of the water ecological region to be evaluated. Figure 2 Step S201 of the illustrated embodiment will not be described in detail here.

[0107] Step S302, based on the ecological environment element set and the comprehensive overview information set, risk assessment is performed on the water ecological area to be assessed to obtain multiple risk assessment results.

[0108] Specifically, the above step S302 includes:

[0109] Step S3021, based on the set of ecological environment elements, the riverbed depth, landform characteristics and vegetation coverage of the water ecological area to be evaluated are determined respectively to obtain multiple first determination results.

[0110] Specifically, it is possible to determine whether the riverbed depth of the water ecological area to be assessed exceeds the standard depth based on the riverbed depth information of the ecological environment factors. If it is much lower than the standard depth, it is unqualified; if it is much higher than the standard depth, it is judged as unqualified.

[0111] Furthermore, it is possible to determine whether the soil on both sides of the water ecological area to be assessed is easily loosened based on the concentrated topography of the ecological and environmental elements. If it is not easy to loosen, it is determined to be qualified soil; if it is easy to loosen, it is determined to be unqualified soil.

[0112] Furthermore, the vegetation coverage rate of the water ecological area to be evaluated can be determined based on the vegetation coverage on both sides of the ecological environment elements. When the vegetation coverage of the water ecological area to be evaluated is high, the coverage rate is judged to be qualified; if the vegetation coverage area is low, the coverage rate is judged to be unqualified.

[0113] Step S3022, based on the comprehensive overview information set, the weather conditions of the water ecological area to be assessed, the basic conditions of the regional rivers and the basic social conditions are determined respectively to obtain multiple second determination results.

[0114] Specifically, the precipitation of the water ecological area to be assessed can be determined based on the weather conditions of the comprehensive overview information. Further, if it is determined that the precipitation in the river basin is relatively high recently, it is determined that there is a risk, and if it is determined that the precipitation in the area is relatively low, it is determined that there is no risk.

[0115] Furthermore, the basic social situation can be concentrated according to the comprehensive overview information. If there are factories, etc., it can be determined that the area may be at risk. If it is determined that there are no factories, the risk situation of the water ecological area to be assessed can be determined based on other pollution in the society. If it is determined that there is other pollution, there is pollution in the river basin. If it is determined that there is no pollution, it can be determined that there may be no danger.

[0116] Furthermore, it is determined whether the basic social conditions of the area provide protection for the vegetation in the water ecological area to be assessed. If so, the risk of the water ecological area to be assessed is reduced. If there is no risk, and based on the occurrence of the above steps, it is determined that there is a risk.

[0117] Step S3023, determining multiple risk determination results according to the multiple first determination results and the multiple second determination results.

[0118] Specifically, the multiple first determination results obtained in step S3021 and the multiple second determination results obtained in step S3022 may be combined to obtain multiple risk determination results:

[0119] A. If all the results are unqualified, the processing module will determine that the water ecological area to be assessed is at high risk;

[0120] B. If the soil is easily loosened, it is determined that the water ecological area to be assessed is at high risk;

[0121] C. If the vegetation is sparse, it is determined that the water ecological area to be assessed may be at moderate risk;

[0122] D. If there is a lot of rainfall, the water ecological area to be assessed is judged to be of medium risk;

[0123] E. If industrial pollution occurs, the water ecological area to be assessed is judged to be of medium risk;

[0124] F. If other pollution conditions, riverbed changes, etc. occur, the water ecological area to be assessed will be judged to be of low risk or no risk.

[0125] Step S303: fuse multiple risk assessment results to obtain multiple risk fusion results.

[0126] Specifically, fusing multiple risk determination results may include:

[0127] (1) Any two risk determination results from A to F obtained in step S3023 are fused to obtain multiple risk fusion results:

[0128] a. A high risk and a high risk fusion situation occurs, that is, the risk fusion result is a high risk;

[0129] b. A combination of high risk and medium risk occurs, i.e. the risk fusion result is high risk;

[0130] c. A combination of high risk and low risk occurs, i.e. the risk fusion result is high risk;

[0131] d. A situation where medium risk and low risk are combined, that is, the risk fusion result is medium danger.

[0132] (2) Any multiple risk determination results from A to F obtained in step S3023 are fused to obtain multiple risk fusion results:

[0133] e: There is a fusion of any high risk, medium risk and low risk, that is, the risk fusion result is high risk;

[0134] f: There is a situation where any medium risk and low risk are merged, that is, the risk fusion result is high risk;

[0135] g: There is a situation where any low-level risks are merged, that is, the risk fusion result is a medium risk.

[0136] Step S304, using multiple risk fusion results to perform risk assessment on the water ecological area to be assessed, to obtain a risk assessment result of the water ecological area to be assessed.

[0137] Specifically, the risk assessment result of the water ecological area to be assessed can be further determined by combining the multiple risk fusion results obtained in step S303.

[0138] In an optional embodiment, the water ecological risk assessment method of the embodiment of the present invention also includes: performing real-time detection on the water ecological area to be assessed and determining whether a risk change corresponding to any risk determination result occurs; when a risk change occurs, changing multiple risk determination results, returning to the step of fusing multiple risk determination results, and iterating repeatedly until a risk assessment result is obtained.

[0139] Specifically, the water ecological area to be assessed can be continuously monitored, covering various indicators related to ecological environmental elements (such as vegetation coverage on both sides of the river, riverbed depth, landform conditions, etc.) and comprehensive overview information (such as weather conditions, basic conditions of regional rivers, basic social conditions, etc.).

[0140] Furthermore, the data obtained from real-time detection can be compared with the risk determination index to determine whether a risk change corresponding to any risk determination result occurs.

[0141] Furthermore, when a risk change is detected, the multiple risk determination results are modified accordingly according to the new situation.

[0142] Furthermore, the modified multiple risk determination results are used to repeatedly execute the above steps S303 to S304 to obtain the final risk assessment result of the water ecological area to be assessed.

[0143] The water ecological risk assessment method provided in this embodiment makes judgments from the perspectives of ecological environmental factors (riverbed depth, geomorphic features, and vegetation coverage) and comprehensive overview information (weather conditions, basic conditions of regional rivers, and basic social conditions), comprehensively covering the key factors affecting the risk of water ecological areas, making risk judgments more detailed and accurate, and avoiding the omission of important risk factors. Further, the risk fusion results are determined by integrating the judgment results from multiple aspects, which can grasp the risk status of the water ecological area as a whole, taking into account the interaction and comprehensive impact of different factors, making the risk assessment results more scientific and reliable. Further, by real-time monitoring of the water ecological area, the risk changes can be captured in a timely manner. Further, the risk judgment results are modified and re-integrated according to the changes, realizing the dynamic update of risk assessment, ensuring that the latest risk status of the water ecological area can be reflected at any time, improving the timeliness and adaptability of risk assessment, and thus being able to better respond to the dynamic changes of the water ecological environment.

[0144] In one example, if FIG. 4A to FIG. 6 As shown, a water environment and water ecological risk assessment and early warning system is provided, including:

[0145] S1. Selection module: The selection module refers to selecting the water ecological environment of a certain area;

[0146] S2, determination module: the determination module is used to determine the vegetation coverage, riverbed and soil in the selected water ecological area;

[0147] S3, fusion module: The fusion module is used to integrate the weather conditions in the region, the basic conditions of the regional rivers, and the impact of the basic social conditions on the region;

[0148] S4, real-time change module: the real-time change module is used to replace the speed of the monitored weather conditions, basic conditions of regional rivers and basic social conditions;

[0149] S5, processing module: the processing module is used to process the fused information of the region;

[0150] S6. Evaluation module: The evaluation module is used to evaluate the information processed in the processing module;

[0151] S7. Early warning module: The early warning module is used to warn whether the evaluated information is harmful.

[0152] In a specific implementation, the specific selection system operation method based on the selection module in the above S1 is: based on the area to be detected, the river basins in the area are divided, and a river basin is easily selected therefrom, and basic detection is performed on the selected river basin information.

[0153] Furthermore, the specific operation method of the determination system based on the determination module in S2 is: according to the above selected river basin, the riverbed depth of the river, the landform characteristics of both banks and the vegetation coverage rate of both banks are determined, which is specifically:

[0154] Combine the basic information of the intercepted river and judge whether the riverbed depth exceeds the standard depth. If it is much lower than the standard depth, it is unqualified; if it is much higher than the standard depth, it is judged as unqualified;

[0155] According to the geomorphological features on both sides of the riverbed, it is determined whether the soil on both sides is easy to loosen; if it is not easy to loosen, it is determined to be qualified soil, and if it is easy to loosen, it is determined to be unqualified soil;

[0156] According to the vegetation coverage on both sides of the river, when the vegetation coverage is high, the coverage rate is judged to be a qualified area, and if the vegetation coverage area is low, the coverage rate is judged to be unqualified.

[0157] Furthermore, the specific determination system operation method based on the determination module in S2 also includes:

[0158] Based on the recent weather changes in the river basin, if it is determined that there has been a lot of precipitation in the river basin recently, it is determined that there is a risk; if it is determined that there has been little precipitation in the area, it is determined that there is no risk;

[0159] At the same time, based on the social situation in the area, if there are factories, it is determined that the area may be at risk. If it is determined that there are no factories, the risk situation in the area is determined based on other pollution in the society. If it is determined that there is other pollution, the basin is polluted. If it is determined that there is no pollution, there may be no danger.

[0160] And based on whether there is protection for the vegetation in the area in the society, if there is protection, the risk of the area will be reduced. If there is no risk, and based on the occurrence of the above steps, it is determined that there is a risk.

[0161] Further, the specific fusion system operation steps based on the fusion module in S3 are as follows: combining several factors in the determination module in S2:

[0162] A. If all are unqualified, the processing module will determine that the area is highly risky;

[0163] B. If the soil is easily loosened, the area is considered to be highly risky;

[0164] C. If the vegetation is sparse, it is judged as a situation with a possible moderate risk;

[0165] D. If there is a lot of rainfall, it is considered as a moderate risk;

[0166] E. If industrial pollution occurs, it is judged as a moderate risk;

[0167] F. If other pollution situations or riverbed changes occur, the danger level is low or there is no danger.

[0168] Furthermore, the change system operation steps based on the real-time change module in the above S4 are: perform real-time situation detection on the intercepted river area according to the detection system. If specific risk changes occur in the above determination system, make timely changes and transmit them to the fusion module for re-integration. If no changes occur, no operation is performed.

[0169] Further, the specific evaluation system operation steps based on the evaluation module in S3 are as follows: based on the fusion of any two of the situations A, B, C, D, E, and F in the determination module in S3:

[0170] a. The situation where high risk and high risk converge is extremely dangerous;

[0171] b. A combination of high risk and medium risk is extremely dangerous;

[0172] c. A high risk is a combination of high risk and low risk;

[0173] d. A combination of medium risk and low risk is considered medium risk;

[0174] If any of the situations A, B, C, D, E, and F in the judgment module are combined:

[0175] e: A high risk occurs when any high risk, medium risk, and low risk merge;

[0176] f: The combination of any medium risk and low risk is considered high risk;

[0177] g: A medium risk is when any low risk is combined.

[0178] Furthermore, the specific system operation steps based on the above-mentioned early warning module are as follows: based on the specific assessment results in the above-mentioned S6, the risk situation is displayed by the processing unit to obtain high risk, medium risk and low risk situations; at the same time, the processing unit divides the high risk, medium risk and low risk into corresponding colors, and corresponds different colors to different areas and indicates different risk situations, and then inserts different colors into the map through the insertion unit, so that the different colors are displayed in the corresponding areas of the map. Due to the provision of a hidden unit, the color of the area cannot be observed before using the map. When the area is enlarged, the different equidistant colors corresponding to the area can be distinguished through the enlarged display unit. At the same time, the specific dangerous situation of the level color corresponding to the area can be explained next to the map for people to observe, so that outsiders can understand the specific situation of the area in time, ensuring the life safety of outsiders and avoiding economic losses of outsiders to a certain extent.

[0179] Furthermore, based on the situation description in the above-mentioned early warning module, the specific operation method also includes: according to the risk situation entered in the map, the risk situation can be analyzed through the analysis unit, and the area can deal with the risk situation and formulate a corresponding governance plan. At the same time, according to the formulated corresponding plan, the area can be governed in time, and the time required for governance of the area can be budgeted, and the information can be updated to the map, so that personnel can timely observe the time when the risk governance of the area is approximately completed, so that personnel can make corresponding arrangements.

[0180] The water environment and water ecological risk assessment and early warning system provided in this example displays the risk situation through the processing unit to obtain high risk, medium risk and low risk situations; at the same time, the processing unit divides the high risk, medium risk and low risk into corresponding colors, and corresponds different colors to different areas and indicates different risk situations, and then inserts different colors into the map through the insertion unit, so that the different colors are displayed in the corresponding areas of the map. Due to the provision of a hidden unit, the color of the area cannot be observed before using the map. When the area is enlarged, the different equidistant colors corresponding to the area can be distinguished through the enlarged display unit. At the same time, the specific dangerous situation of the level color corresponding to the area can be explained next to the map for people to observe, so that outsiders can understand the specific situation of the area in time, ensure the life safety of outsiders, and avoid economic losses of outsiders to a certain extent.
