[0051] The present invention obtains the basic data of the river to be managed, collects water quality index information in the basic data of the river, and can clearly grasp various water quality indicators by accurately acquiring and analyzing these data. Based on accurate water quality indicators, the focus and direction of management can be clarified to avoid blind management, thereby improving management efficiency and effectiveness.

[0052] The river to be managed refers to a river that has been damaged in its ecological environment, deteriorated in water quality, and obstructed in water flow due to various reasons, such as pollution from human activities and the influence of natural factors, and needs to be managed and repaired to restore its normal function and ecological balance; the basic river data refers to a series of basic information related to the river to be managed, including the geographical location, length, width, depth, slope of the river, material and stability of the river bank, and surrounding land use type; the water quality index information refers to a series of specific parameters used to measure the water quality of the river, such as pH value, dissolved oxygen (DO), chemical oxygen demand (COD), biochemical oxygen demand (BOD), ammonia nitrogen, total phosphorus, total nitrogen, heavy metal content, number of Escherichia coli, etc. Optionally, the acquisition of the basic river data of the river to be managed can be achieved by river measuring instruments, such as total stations, levels, etc.; the collection of water quality index information in the basic river data can be achieved by water quality sensors, such as conductivity sensors, turbidity sensors, etc.

[0053] By constructing an indicator sequence corresponding to the water quality indicator information, the present invention can clearly see the changing trends of various water quality indicators, such as whether the dissolved oxygen is gradually increasing and whether the chemical oxygen demand is continuously decreasing, which helps to accurately evaluate the effectiveness of treatment measures and promptly discover potential problems or room for improvement.

[0054] Among them, the indicator sequence refers to a data set composed of a series of key indicator characteristics arranged in a certain time sequence or logical relationship. For example, the key indicator characteristics such as COD value and dissolved oxygen value of each day in a period of time are arranged in chronological order to form a sequence that can clearly show the law of water quality changes.

[0055] As an embodiment of the present invention, the construction of an indicator sequence corresponding to the water quality index information includes: performing data cleaning on the water quality index information to obtain cleaned index data; converting the data format corresponding to the cleaned index data to obtain standard format data; extracting key indicator features in the standard format data; and constructing an indicator sequence corresponding to the water quality index information based on the key indicator features.

[0056] Among them, the cleaning index data refers to the data obtained after removing the errors, missing values, duplicate data and obviously abnormal data in the water quality index information. For example, the original water quality index data contains some extreme values ​​that are obviously deviated from the normal range, or data in certain time periods are missing. The accurate, complete and reasonable data obtained after processing is the cleaning index data; the standard format data refers to the data obtained after the cleaned index data is converted according to unified specifications and standards, for example, the cleaning index data from different sources, different units, and different recording methods are converted into a unified unit, unified data structure and storage format, so as to facilitate subsequent processing and analysis; the key indicator characteristics refer to the important indicator attributes that can reflect the essential characteristics and changing laws of water quality in the standard format data. For example, the chemical oxygen demand for measuring the degree of organic pollution in water bodies.

[0057] Furthermore, the data cleaning of the water quality index information can be achieved through data filtering tools, such as the screening function of Excel, which can quickly screen out data that does not meet specific conditions; the conversion of the data format corresponding to the cleaned index data can be achieved through ETL tools, such as Apache Kafka, Ta l end and other tools; the extraction of key indicator features in standard format data can be achieved through clustering analysis methods, such as K-Means clustering, which classifies similar data points into one category to discover key features; the construction of the indicator sequence corresponding to the water quality index information can be achieved through a time series analysis library, such as the statsmode ls library in Python, to model and analyze time series.

[0058] By extracting the key pollution factors in the indicator sequence, the present invention can help quickly focus on the pollutants that have the most serious impact on river water quality, thereby formulating targeted governance strategies, avoiding blind exploration among numerous pollution factors, and improving governance efficiency.

[0059] Among them, the key pollution factors refer to those pollutant components or indicators that have significant and major impacts on river water quality, ecosystem and surrounding environment among the many factors that cause river pollution. Optionally, the extraction of key pollution factors in the indicator sequence can be achieved through factor analysis methods, such as hierarchical cluster analysis, principal component analysis and other methods.

[0060] S2. Conduct pollution source tracing analysis on the key pollution factors to obtain pollution distribution sources, identify the main pollution sources in the pollution distribution sources, and calculate the pollution concentration value corresponding to the main pollution sources.

[0061] The present invention obtains the pollution distribution source by performing pollution source tracing analysis on the key pollution factors, which can identify the specific pollution source, prevent the expansion of the pollution scope and the deepening of the harm degree, and help to establish a long-term supervision mechanism, thereby avoiding the waste of resources caused by blind governance.

[0062] The pollution distribution source refers to the initial location or main emission source that is finally determined to cause the key pollution factors to be widely distributed in the river to be treated.

[0063] As an embodiment of the present invention, the pollution source tracing analysis is performed on the key pollution factors to obtain the pollution distribution source, including: collecting factor distribution data corresponding to the key pollution factors in the river to be treated; querying the factor characteristics in the factor distribution data; analyzing the propagation path corresponding to the factor characteristics; preliminarily locating the path pollution source corresponding to the propagation path; and performing pollution source tracing analysis on the path pollution source to obtain the pollution distribution source.

[0064] Among them, the factor distribution data refers to a data set of detailed information such as the concentration and existence form of key pollutants in different locations and different time periods of the river to be treated, for example, the content data of a certain heavy metal in the upper, middle and lower reaches of the river at different times of the day; the factor characteristics refer to the unique properties and manifestations of key pollutants, such as concentration change patterns, chemical forms, correlation with other substances, etc.; the transmission path refers to the specific route and method of the key pollutants moving and diffusing in the river with water flow, air flow or other media; the path pollution source refers to the source that may produce the pollution factor on the transmission path of the key pollutant.

[0065] Furthermore, the collection of factor distribution data corresponding to the key pollution factors in the river to be treated can be achieved through machine learning algorithms, such as random forests, support vector machines, etc.; the query of factor features in the factor distribution data can be achieved through feature selection algorithms, such as PCA, I CA and other algorithms; the analysis of the propagation path corresponding to the factor features can be achieved through hydrodynamic models, such as HEC-RAS, MI KE and other models; the preliminary positioning of the path pollution source corresponding to the propagation path can be achieved through a tracing algorithm, such as a reverse trajectory model, source analysis technology, etc.; the pollution source tracing analysis of the path pollution source can be achieved through a deep learning algorithm, such as CNN, RNN and other algorithms.

[0066] By identifying the main pollution sources in the pollution distribution sources, the present invention can concentrate limited resources and energy to solve the most important problems, avoid the dispersion and waste of resources, and formulate more scientific and effective prevention strategies and regulatory measures to prevent similar pollution problems from happening again.

[0067] Among them, the main pollution source refers to the one or those pollution sources that play a dominant and decisive role in the formation, development and degree of harm of river pollution among the many pollution sources that cause river pollution. Optionally, the identification of the main pollution source in the pollution distribution source can be achieved through a variety of analysis methods, such as: AHP, PCA and other methods.

[0068] By calculating the pollution concentration value corresponding to the main pollution source, the present invention can intuitively understand the degree of damage caused by the main pollution source to the environment, and can effectively monitor the control effect, so as to more accurately judge its severity and urgency.

[0069] The pollution concentration value refers to the ratio of the content of a certain pollutant to the total volume or total mass of the medium in a specific environmental medium (such as wastewater, waste gas, soil, etc.).

[0070] As an embodiment of the present invention, the calculating the pollution concentration value corresponding to the main pollution source includes:

[0074] In detail, the time period refers to the interval of a certain length into which the monitoring time is divided in order to more comprehensively and accurately assess the pollution situation of the main pollution source; the concentration of the emitted pollutants refers to the content of specific pollutants contained in wastewater, waste gas and other substances when the main pollution source discharges them; the weight coefficient refers to the numerical value of relative importance assigned according to the various characteristics of the pollutant (such as toxicity, degree of harm to the ecosystem, persistence in the environment, etc.). The larger the value, the higher the importance of the pollutant in the calculation.

[0075] S3. Based on the pollution concentration value, determine the siltation area corresponding to the river to be treated, desilt the siltation area to obtain a desilted river, conduct ecological monitoring of the desilted river to obtain ecological monitoring data, and determine the ecological restoration area corresponding to the river to be treated based on the ecological monitoring data.

[0076] The present invention determines the siltation area corresponding to the river to be treated based on the pollution concentration value, which can effectively prevent further siltation of the river and promptly clean up the siltation area with high pollution concentration, thereby reducing the accumulation and precipitation of pollutants, reducing the risk of re-siltation of the river, and maintaining the patency of the river and the balance of the water ecology.

[0077] Among them, the siltation area refers to an area where a large amount of silt, pollutants and other substances have accumulated in the river channel, resulting in a reduction in the water-passing section of the river channel and poor water flow. For example, thick silt and pollutants have accumulated at the bottom of the river channel, seriously affecting the normal flood discharge and ecological functions of the river channel.

[0078] As an embodiment of the present invention, determining the siltation area corresponding to the river to be treated based on the pollution concentration value includes: integrating the pollution concentration value data to obtain concentration integration data; drawing a concentration contour map corresponding to the river to be treated based on the concentration integration data; identifying the concentration change gradient corresponding to the concentration contour map; analyzing the change sedimentation area corresponding to the concentration change gradient; and determining the siltation area corresponding to the river to be treated based on the change sedimentation area.

[0079] Among them, the concentration integration data refers to the data set obtained by summarizing, organizing and unifying the pollution concentration values ​​from different monitoring points and different time periods; the concentration contour map refers to a graph composed of curves connecting points with the same pollution concentration on a map or a plane map; the concentration change gradient refers to the rate of change of pollution concentration in space or time, that is, the degree of difference in concentration values ​​between two adjacent concentration contour lines; the variable deposition area refers to a specific area where pollutants are more likely to settle due to changes in pollution concentration, which is usually related to factors such as water flow velocity and topography.

[0080] Furthermore, the data integration of the pollution concentration values ​​can be achieved through data fusion algorithms, such as Kalman filtering, Bayesian estimation, etc.; the drawing of the concentration contour map corresponding to the river to be managed can be achieved through visualization tools, such as Matplotlib, Seaborn and other tools; the identification of the concentration change gradient corresponding to the concentration contour map can be achieved through gradient calculation methods, such as finite difference method, gradient descent method and other methods; the analysis of the change sedimentation area corresponding to the concentration change gradient can be achieved through machine learning methods, such as random forest, support vector machine and other methods; the determination of the siltation area corresponding to the river to be managed can be achieved through optimization algorithms, such as genetic algorithms, particle swarm optimization and other algorithms.

[0081] The present invention obtains a desilted river channel by desilting the silted area. Desilting can increase the volume of the river channel, so that it can store more water resources during drought periods, enhance the self-purification capacity of the river channel, and maintain the normal function and ecological balance of the river channel.

[0082] Among them, the desilted river channel refers to a river channel in which, after cleaning and dredging operations on the silted area, the silt in the river channel is effectively removed, the water-passing section is restored and expanded, the water flow is smoother, the water quality is improved, and the overall function and ecological environment are optimized; the desilting of the silted area can be achieved by dredging equipment, such as: dredgers, suction dredgers and other equipment.

[0083] Furthermore, the present invention obtains ecological monitoring data by conducting ecological monitoring of the dredged river channel, which can timely and accurately evaluate the actual effect of the dredging work, help discover potential ecological problems and risks, and formulate reasonable water resource management, biodiversity protection, and pollution prevention and control strategies in a targeted manner to ensure the long-term stability and healthy development of the river ecosystem.

[0086] Among them, the ecological restoration area refers to a specific area in the river to be managed where the ecological conditions have seriously deteriorated, the functions are obviously missing or damaged, and special restoration measures are needed to restore its ecological balance and functions.

[0087] As an embodiment of the present invention, determining the ecological restoration area corresponding to the river to be managed based on the ecological monitoring data includes: performing data preprocessing on the ecological monitoring data to obtain preprocessed ecological data; performing an ecological comprehensive assessment of the river to be managed based on the preprocessed ecological data to obtain an ecological comprehensive status; querying the degree of ecological damage in the ecological comprehensive status; and determining the ecological restoration area corresponding to the river to be managed based on the degree of ecological damage.

[0090] S4. Query the ecological status corresponding to the ecological restoration area, calculate the ecological restoration cost corresponding to the ecological restoration area based on the ecological status, optimize the allocation resources in the river management process based on the ecological restoration cost, and calculate the resource utilization efficiency corresponding to the allocation resources.

[0091] The present invention helps to timely discover new ecological problems by querying the ecological status corresponding to the ecological restoration area, and querying the ecological status can quickly capture these problems, so as to take corresponding countermeasures and improve the subsequent restoration efficiency of the river environment.

[0092] Among them, the ecological status refers to the actual state and characteristics of the ecosystem presented by the ecological restoration area within a specific time and space scope. Optionally, the query of the ecological status corresponding to the ecological restoration area can be achieved through data analysis algorithms, such as regression analysis, correlation analysis and other algorithms.

[0093] Furthermore, based on the ecological status quo, the present invention calculates the ecological restoration cost corresponding to the ecological restoration area, which can provide a key basis for the planning and decision-making of the restoration project, clarify the specific restoration cost, and help to rationally arrange resources to ensure the maximum ecological benefit within a limited budget.

[0099] In detail, the investment cost refers to the cost incurred for introducing special facilities and technologies to improve the effect of ecological restoration, such as the expenditure on purchasing advanced sewage treatment equipment, installing ecological monitoring instruments, and adopting new ecological restoration technologies; the deterioration degree coefficient refers to a value determined after a detailed assessment of the ecological status of the ecological restoration area, which reflects the degree of poor ecological conditions in the area. The closer the value is to 1, the worse the ecological status is, the greater the difficulty of restoration and the required resource input; the closer the value is to 0, the relatively good ecological status is, and the difficulty and input of restoration are relatively small; the comprehensive adjustment coefficient refers to a coefficient set by taking into account other factors affecting the cost in addition to the ecological status itself. These factors may include price differences in different regions, policy requirements for restoration standards, changes in market supply and demand, and special geographical conditions.

[0100] Furthermore, the present invention optimizes the allocation of resources in the process of river management based on the ecological restoration cost, which can ensure that limited funds are allocated in the most reasonable way, avoid waste and abuse of resources, reserve sufficient resources and space for future maintenance and management, and ensure the long-term stability and health of the river ecosystem.

Optionally, the optimization of resource allocation in the river management process based on the ecological restoration cost can be achieved through optimization algorithms, such as simulated annealing algorithms, genetic algorithms, etc.

[0102] By calculating the resource utilization efficiency corresponding to the configured resources, the present invention can prompt relevant departments and personnel to pay more attention to the rational use of resources, avoid waste and abuse, strengthen the refined management of resources, and thus improve the management efficiency of resources.

[0103] Among them, the resource utilization efficiency refers to the ratio between the various types of resources invested and the management effects achieved in the river management process, which reflects the effectiveness of resources in converting into actual management results.

According to the accurate water quality indicators, the focus and direction of governance can be clarified to avoid blind governance, thereby improving the efficiency and effect of governance. At the same time, the present invention obtains the source of pollution distribution by tracing the pollution source of the key pollution factors, and can clarify the specific pollution source, prevent the expansion of the pollution scope and the deepening of the harm degree, and help to establish a long-term supervision mechanism, thereby avoiding the waste of resources caused by blind governance. The present invention determines the siltation area corresponding to the river to be governed based on the pollution concentration value, which can effectively prevent the river from being silted up. In order to prevent the river from further silting up, timely cleaning of silted areas with high pollution concentrations can reduce the accumulation and precipitation of pollutants, reduce the risk of re-silting up of the river, and maintain the smooth flow of the river and the balance of the water ecology. The present invention helps to timely discover new ecological problems by querying the ecological status corresponding to the ecological restoration area, and querying the ecological status can quickly capture these problems, so as to take corresponding countermeasures and improve the efficiency of subsequent river environment restoration. Furthermore, based on the resource utilization efficiency, the present invention generates a benefit evaluation index corresponding to the river to be governed, comprehensively considers the relationship between resource input and output, makes the evaluation more accurate and comprehensive, and helps to accurately identify the advantages and disadvantages in the governance process, and provides a clear direction for subsequent improvements. Therefore, the comprehensive governance method and system for river governance proposed in the present invention can improve the governance effect of river governance.
