[0002] In the field of aquatic environmental management and protection, the quality of sediment plays a vital role in the stability of aquatic ecosystems and the maintenance of water quality. The organic and inorganic components in sediment have an important impact on processes such as eutrophication, biological growth, and pollutant transport in water bodies. In order to avoid secondary pollution of sediment, provide a good growth environment for aquatic plants and animals, and ensure the stability of the aquatic ecosystem, by analyzing the impact of sediment on water quality, studying substrate disinfection and substrate trace element ratio measures to create lake habitats and improve the substrate environment. Therefore, accurate analysis and evaluation of sediment composition is of great significance for the effective management of aquatic resources and improvement of water quality environment.
[0003] Traditional methods for analyzing sediment composition usually rely on field sampling and chemical analysis. This method has problems such as insufficient sampling, long data acquisition cycle, and high cost, which limits the monitoring and assessment of large areas of water. Summary of the invention

[0009] S4. Perform ecosystem simulation and emulation based on the water quality change trend data to obtain ecosystem stability index data for base improvement construction assessment operations.
[0010] In the present invention, by collecting and extracting features from the sediment images of the water area, the composition and characteristics of the sediment can be deeply understood, so as to accurately evaluate the quality of the substrate and the need for improvement. The sediment component association processing can deeply analyze the correlation between the organic and inorganic components in the sediment, which helps to identify the source of the sediment, the degree of pollution and the impact on the water quality. Through the prediction of water quality change trends, the changing trend of water quality after sediment improvement can be predicted, including the improvement or decline of water quality, to provide guidance and early warning for improvement construction. Ecosystem simulation and emulation can simulate various dynamic changes of aquatic ecosystems, obtain ecosystem stability index data, and more accurately evaluate the impact of improvement construction on the stability of aquatic ecosystems. Based on the ecosystem stability index data, the substrate improvement construction can be scientifically guided to ensure that the impact of the construction process on the aquatic ecosystem is minimized and the ecological environment quality of the aquatic area is maximized.

Sediment component association processing can reveal the association rules between various organic and inorganic components in sediment. By mining these association rules, the complexity and change trend of sediment components can be better understood. Based on sediment component association data, water quality change trend prediction can be carried out, and the change trend of water quality in water area can be effectively predicted, including the change direction, rate and influencing factors of water quality parameters, etc., providing a scientific basis for water area ecological environment management and protection, and showing the change and development of water area ecosystem. Ecosystem simulation and simulation are carried out using water quality change trend data to simulate the dynamic change process of water area ecosystem under different water quality conditions. By evaluating the stability index of the ecosystem, the impact of water quality changes on the ecosystem is reflected, and a reference is provided for the evaluation of base improvement construction. Ecosystem stability index data provides scientific guidance for base improvement construction. By comprehensively considering water quality change trends and ecosystem stability, targeted base improvement plans can be formulated to minimize the impact on the ecological environment, ensure the sustainability and ecological safety of construction, and contribute to protecting the natural environment and achieving harmonious coexistence between man and nature.

[0026] See also Figures 1 to 4 The present application provides a method for evaluating substrate improvement construction, the method comprising:
[0027] S1, collecting bottom mud images of the water area by an image acquisition device to obtain low mud image data of the water area, and extracting organic bottom mud features and inorganic bottom mud features from the low mud image data of the water area to obtain organic bottom mud feature data and inorganic bottom mud feature data;
[0028] Specifically, an underwater camera or a submersible is used to collect sediment images in the target waters, and the collected sediment image data is processed and analyzed to extract the characteristics of organic sediment and inorganic sediment, such as color, texture, particle size, etc., to obtain organic sediment characteristic data and inorganic sediment characteristic data.
[0029] S2, performing sediment component correlation processing according to the organic sediment characteristic data and the inorganic sediment characteristic data to obtain sediment component correlation data;
[0030] Specifically, the characteristic data of organic sediment and inorganic sediment are subjected to association analysis, such as using statistical methods or machine learning algorithms to mine the correlation and regularity between them, and obtain sediment component association data, including information such as the degree of association between them, frequency distribution, etc. The correlation coefficient between the features is calculated to understand the linear correlation between them, and the correlation coefficient includes the Pearson correlation coefficient, the Spearman correlation coefficient, etc. For variance analysis, it is possible to analyze whether there is a significant difference in the variance between the features to determine their contribution to the sediment components. It can also be carried out in the form of model analysis, such as model construction through existing historical data to establish a sediment component association analysis model, and the organic sediment characteristic data and the inorganic sediment characteristic data are subjected to sediment component association processing through the sediment component association analysis model to obtain sediment component association data. The construction steps of the model construction are specifically: obtaining historical organic sediment characteristic data, historical inorganic sediment characteristic data, and sediment component association relationship data; generating a decision tree according to the historical organic sediment characteristic data, the historical inorganic sediment characteristic data, and the sediment component association relationship data to obtain a sediment component association analysis model.
[0031] S3, predicting the water quality change trend according to the sediment component correlation data to obtain water quality change trend data;
[0032] Specifically, based on the existing sediment component correlation data, a water quality change trend prediction model is established. For example, time series analysis, regression analysis or neural network methods are used for prediction to obtain trend data of water quality changes in the future, including information such as the direction of change of water quality parameters and trend amplitude.
[0033] Specifically, in another embodiment, the water quality index is used to comprehensively evaluate the pollution degree and change trend of the water body. The water quality index is calculated based on different water quality parameters and weights, and is a single index or a combination of multiple indexes. The monitoring data is analyzed based on the change trend of the water quality index to predict the future change trend of water quality. For example, according to the importance and influence of the water quality parameters, the corresponding weight is determined for each parameter. For example, dissolved oxygen has a greater impact on the ecological health of the water body and is given a higher weight; while total phosphorus mainly affects the eutrophication degree of the water body and is given a lower weight. The water quality index is calculated based on the selected water quality parameters and the corresponding weights. A simple weighted summation method can be used, or a more realistic calculation formula can be used based on the concentration of different parameters and water quality standards. The calculation result of the water quality index will reflect the comprehensive pollution degree of the water body.
[0034] have water quality parameters, denoted as X1, X2, X3, ..., X n , their concentrations are C1, C2, C3, …, C nThe corresponding water quality standard values are S1, S2, S3, ..., S n . The water quality parameter X i and the corresponding water quality standard value S i The difference between them is taken as the predictor variable, namely Δ i =C i -S i , indicating the parameter X i According to the interaction between parameters, a multivariate linear regression model is constructed to predict the water quality index. The form of the model is as follows: ; … is the weighted coefficient corresponding to the deviation degree of different water quality parameters, is the initial value of the water quality index.
[0035] Specifically, in another embodiment, the water quality change trend is modeled and predicted using the statistical characteristics of time series data, such as mean, variance, trend, periodicity, etc. Traditional time series analysis methods, such as moving average, exponential smoothing, ARIMA model, etc., are used to analyze the historical change patterns of water quality data and predict future water quality change trends.
[0036] Specifically, in another embodiment, a water quality model is established to simulate the pollution diffusion and change process of the water body. The water quality model can simulate the transmission, transformation and diffusion of pollutants in the water body based on physical principles or empirical formulas, combined with hydrological, hydrodynamic and other parameters. By simulating the impact of different pollution sources and changes in hydrological conditions, the trend of water quality changes in the future can be predicted. The parameters of the empirical formula are generated by consulting or querying the hydrological data or information stored in the database for parameter extraction.
[0037] S4. Perform ecosystem simulation and emulation based on the water quality change trend data to obtain ecosystem stability index data for base improvement construction assessment operations.
[0038] Specifically, using water quality change trend data as input parameters, combined with existing ecosystem models and simulation software, ecosystem simulation and simulation analysis are carried out. By simulating the impact of water quality changes on the ecosystem, the impact of different base improvement schemes on ecosystem stability is evaluated, and finally ecosystem stability index data is obtained, providing a scientific basis for base improvement construction evaluation.
[0039] Specifically, according to the data of ecological characteristics, topography, environmental parameters and other data of the water area, an ecosystem model is established, including the description of ecological processes such as aquatic vegetation distribution, aquatic animal community structure, and nutrient circulation. The water quality change trend data is integrated with the ecosystem model as the input parameters of the simulation, including the concentration change of water quality parameters, the change trend of water quality index and other information. In the simulation process, different substrate improvement schemes are simulated according to the water quality change trend data, including measures such as changing the bottom of the water body, vegetation planting, and bioremediation. Through simulation, the impact of different substrate improvement schemes on the ecosystem is evaluated, including changes in the degree of water quality improvement, biodiversity, and changes in ecosystem structure and function. According to the simulation results, the stability indicators of the ecosystem are calculated, such as the stable state, tolerance, and recovery capacity of the ecosystem. These indicators can reflect the response capacity and stability of the ecosystem to external interference. The obtained ecosystem stability index data are compared and analyzed with the effects of different substrate improvement schemes to provide a scientific basis for the evaluation of substrate improvement construction.
[0040] In the present invention, by collecting and extracting features from the sediment images of the water area, the composition and characteristics of the sediment can be deeply understood, so as to accurately evaluate the quality of the substrate and the need for improvement. The sediment component association processing can deeply analyze the correlation between the organic and inorganic components in the sediment, which helps to identify the source of the sediment, the degree of pollution and the impact on the water quality. Through the prediction of water quality change trends, the changing trend of water quality after sediment improvement can be predicted, including the improvement or decline of water quality, to provide guidance and early warning for improvement construction. Ecosystem simulation and emulation can simulate various dynamic changes of aquatic ecosystems, obtain ecosystem stability index data, and more accurately evaluate the impact of improvement construction on the stability of aquatic ecosystems. Based on the ecosystem stability index data, the substrate improvement construction can be scientifically guided to ensure that the impact of the construction process on the aquatic ecosystem is minimized and the ecological environment quality of the aquatic area is maximized.
[0041] Optionally, the collecting of bottom mud images of the water area by an image collection device to obtain low mud image data of the water area includes:
[0042] S11, collecting water area images through GIS equipment to obtain water area image data;
[0043] Specifically, aerial photography drones or satellite remote sensing technology are used to collect high-resolution images of the target water area to obtain image data of the water area.
[0044] S12, identifying the main body of the water area according to the water area image data to obtain the main body data of the water area;
[0045] Specifically, the image of the water area is analyzed and identified by using image processing and computer vision technology, and the main targets or features in the water area, such as water bodies, land, buildings, etc., are extracted to obtain the main data of the water area. The water area image is preprocessed, including denoising, grayscale, image enhancement and other operations. Image processing technology and feature extraction algorithm are used to extract representative features from the preprocessed image, including color, texture, shape, etc. Different areas or targets in the image are segmented, and targets such as water bodies, land, buildings, etc. are distinguished. The segmentation methods include threshold segmentation, edge detection, region growing, etc. The segmented image areas are identified and classified by using machine learning algorithms, deep learning models or traditional image classification algorithms (generally preset neural network models), and they are classified into different main categories such as water bodies, land, buildings, etc. The main data of the water area after identification and classification is output in a structured form, such as pixel coordinates, bounding box information, category labels, etc., for subsequent processing and analysis.
[0046] The specific steps of recognition and classification are as follows: extract features from the segmented image area, including color histogram, texture features (such as LBP, GLCM), shape features (such as edge detection results), corner features, etc. Represent the extracted features in vector form, and generally concatenate the features of each image area into a feature vector. Preprocess the extracted features, including normalization, standardization, or other data conversion methods. Select a specific machine learning classifier, such as support vector machine (SVM), K-nearest neighbor (K-NN), decision tree, etc. Use a labeled training data set to train the selected classifier. During the training process, the classifier will learn how to correctly classify the image area into main categories such as water, land, and buildings based on the provided image features. Use the validation data set to evaluate the trained classifier to evaluate its classification performance. Evaluation indicators include accuracy, recall, F1 score, etc.
[0047] The specific process of K-NN is as follows: the input training data set contains image regions and feature vectors that have been labeled with categories. During the training process, the distance or similarity between each sample needs to be calculated. After the training is completed, the K-NN algorithm will obtain a model for classification. The specific training process is as follows: select the K value (number of neighbors) and determine the distance measurement method (such as Euclidean distance, Manhattan distance, etc.). For each training sample, calculate the distance or similarity between it and all other samples, and calculate it using the selected distance measurement method. For each sample, according to the calculated distance or similarity, select the K samples closest to it as its neighbors. For each sample to be classified, vote according to the categories of its K nearest neighbors, select the category with the most occurrences among the K neighbors as the category of the sample, and use the category obtained by voting as the predicted category of the sample. The performance of the algorithm can be optimized by adjusting hyperparameters such as the K value and the distance measurement method.
[0048] S13, extracting water area boundaries from the water area image data according to the water area main body data to obtain water area boundary data;
[0049] Specifically, based on the main data of the water area, the boundary information of the water area is extracted from the water area image using image processing and edge detection algorithms to obtain the water area boundary data. For example, the water area image is preprocessed, including denoising, grayscale, image enhancement and other operations. Edge detection algorithms such as Sobel, Canny, Prewitt, etc. are used to detect the edge of the preprocessed image, and the areas with large grayscale changes in the image are identified, which will generate a series of edge points. The detected edge points are connected to connect adjacent edge points into line segments or curves, such as Hough Transform. The connected edges are screened, and the line segments or curves related to the water boundary are retained. The screening is based on the length, direction, shape and other features to exclude the interference of non-water boundary. The boundary of the water area is determined based on the screened edge segments or curves, and further processing such as closed curves and filled areas is performed to obtain complete water boundary information.
[0050] S14, performing topographic analysis and environmental parameter extraction according to the water area boundary data to obtain topographic data and environmental parameter data;
[0051] Specifically, geographic information system (GIS) tools are used to conduct topographic analysis of water boundary data, including the extraction of parameters such as water depth and terrain elevation. At the same time, environmental parameters such as water quality, temperature, salinity and other data are extracted based on the water area location and topographic characteristics.
[0052] S15. Determine the deployment position according to the water area boundary data, the topographic data and the environmental parameter data to obtain the deployment position data, and collect the bottom mud image of the water area through the image acquisition device to obtain the low mud image data of the water area.
[0053] Specifically, the optimal deployment location of the image acquisition equipment is determined based on the water area boundary, topography and environmental parameter data to ensure comprehensive and accurate collection of water area bottom mud image data, thereby obtaining water area low-mud image data. The equipment includes underwater cameras, submersibles, etc.
[0054] The present invention collects water area image data through GIS equipment, and can accurately obtain image information of the water area, including the scope, shape and surrounding environment of the water area. By performing water area subject identification and water area boundary extraction on the water area image data, the boundary of the water area can be accurately identified, and the specific scope and position of the water area can be determined. According to the water area boundary data, topographic and geomorphic analysis and environmental parameter extraction can be performed, and the topographic and geomorphic characteristics of the water area and the surrounding environmental parameters can be reasonably analyzed, providing a basis for the subsequent deployment position determination. In combination with the water area boundary data, topographic and geomorphic data and environmental parameter data, the best deployment position can be scientifically determined to ensure that the image acquisition device can effectively cover the water area and obtain accurate sediment image data. By analyzing the water area information and environmental conditions and determining the appropriate deployment position, the data acquisition efficiency and accuracy of the image acquisition device can be improved, and high-quality data support can be provided for the subsequent sediment feature extraction.
[0055] Optionally, extracting water area boundaries from the water area image data according to the water area main body data to obtain water area boundary data includes:
[0056] S131, extracting edge water area boundaries from the water area image data according to the water area main body data to obtain first water area boundary data;
[0057] Specifically, the edge detection algorithm is used to extract the edge part, that is, the boundary information of the water area, from the water area image to obtain the first water area boundary data. For example, the water area image is preprocessed, including denoising, grayscale, image enhancement and other operations. Edge detection algorithms such as Sobel, Canny, Prewitt, etc. are used to perform edge detection on the preprocessed image to identify the area with large grayscale changes in the image, which usually generates a series of edge points. The detected edge points are connected to connect adjacent edge points into line segments or curves, such as Hough Transform. The connected edges are screened, and the line segments or curves related to the water area boundary are retained. The screening is performed based on the length, direction, shape and other features to exclude the interference of non-water area boundaries. The boundary of the water area is determined based on the screened edge segments or curves, and further processing such as closing curves and filling areas is performed to obtain complete water area boundary information.
[0058] More importantly, edge point extraction is performed on the water area image data according to the water area main body data to obtain water area edge point data; edge connection is performed on the water area edge point data to obtain water area edge connection data; similarity screening is performed on the water area edge connection data to obtain first water area boundary data; wherein the similarity screening is performed by calculating the water area similarity calculation formula to obtain the water area similarity index for screening, and the water area similarity calculation formula is specifically:
[0059] ;
[0060] is the water area similarity index, is the sequence item data corresponding to the edge connection data of the water area, is the quantity data corresponding to the edge connection data of the water area, is similarity weighted data, is the similarity index of the water area edge connection data and the water area main data. , calculate its relationship with the main data of the water area Similarity index This similarity index can be defined based on specific features and measurement methods, such as the distance or similarity measurement between feature vectors. Then, each similarity index is multiplied by its corresponding weighting coefficient. , and sum all items to get the total similarity index . Each water area edge connection data There is a corresponding similarity weight coefficient These weights are determined based on their importance in the similarity calculation. For example, if certain edge connection data are more critical in identifying water boundaries, they can be given higher weights. Once the overall similarity index is calculated , set a threshold to filter out the water area edge connection data that meets the requirements. For example, if the similarity between the boundary connection data and the preset main data is required to reach a certain level, then set a corresponding threshold. All boundary connection data with a similarity index higher than the threshold will be retained to form the first water area boundary data.
[0061] S132, performing hydrodynamic simulation processing according to the main body data of the water area to obtain water area hydrodynamic simulation data;
[0062] Specifically, based on the main data of the water area, numerical simulation methods (such as computational fluid dynamics models) are used to simulate and calculate the hydrodynamic characteristics of the water flow, waves, etc. in the water area to obtain the hydrodynamic simulation data of the water area. For example, the water flow in the water area is simulated by hydrodynamic simulation software (such as MIKE model, Delft3D, etc.), including parameters such as water flow speed, water flow direction, and water depth. These simulation data are obtained through numerical calculations and reflect the flow of water bodies at different locations.
[0063] S133, extracting a water area boundary from the water area image data according to the water area hydrodynamic simulation data to obtain second water area boundary data;
[0064] Specifically, the hydrodynamic simulation data is used to determine the areas with higher flow velocity in the water area, which are located near the boundary of the water body. The hydrodynamic simulation data can be combined with the water area image data using image processing technology to extract the areas with higher water velocity or shallower water depth, thereby determining the boundary position of the water area, thereby obtaining the water area boundary information based on the hydrodynamic simulation data. These boundary data are a series of coordinate points or boundary line segments, representing the boundary contour of the water area, and obtaining the second water area boundary data.
[0065] A hydrodynamic simulation of a lake was performed to obtain water flow velocity data at different locations in the lake. The boundary position of the lake was determined based on the change in water flow velocity. Generally speaking, the water flow velocity at the boundary of the lake will be larger because the lake is in contact with the external environment and the water flow velocity is greatly affected by external factors. Using this feature and combining image processing technology, the areas with larger water flow velocity are extracted from the water area image, and then the boundary position of the lake is determined based on the distribution of these areas. Finally, these boundary positions are sorted into boundary segments or coordinate points to obtain the second water area boundary data.
[0066] The specific steps of extracting the area with higher water velocity from the water area image are as follows: aligning the hydrodynamic simulation data with the water area image to ensure that the two correspond accurately in spatial position. Preset a threshold value, and mark the pixel points in the hydrodynamic simulation data where the water velocity exceeds the threshold as the area with higher water velocity. Starting from a seed point in the water area image, according to certain growth criteria (such as the similarity of water velocity of adjacent pixels), the region is gradually grown until the condition of stopping growth is met to form an area with higher water velocity. Use edge detection algorithms (such as Canny operator, Sobel operator, etc.) to detect the edges with higher water velocity in the water area image, so as to obtain the area with higher water velocity. Post-process the extracted area with higher water velocity, including removing discontinuous areas, filling holes, smoothing boundaries, etc., to extract the area with higher water velocity.
[0067] S134, performing boundary comparison on the first water area boundary data and the second water area boundary data to obtain boundary comparison data;
[0068] Specifically, the first water area boundary data and the second water area boundary data are compared to find out the differences and overlaps between them and obtain boundary comparison data.
[0069] S135, when it is determined that the boundary comparison data is boundary overlap data, boundary data fusion is performed on the boundary comparison data corresponding to the boundary overlap data to obtain water area boundary data;
[0070] Specifically, if it is found that there are overlapping parts in the boundary comparison data, that is, boundary overlapping data, then these data are fused to obtain the final water area boundary data.
[0071] S136. When it is determined that the boundary comparison data is boundary overlap data, the first water area boundary data corresponding to the boundary overlap data is corrected according to the second water area boundary data corresponding to the boundary overlap data to obtain the water area boundary data; or, historical water area boundary data is obtained, and boundary correction is performed on the second water area boundary data corresponding to the boundary overlap data and the first water area boundary data corresponding to the boundary overlap data according to the historical water area boundary data to obtain the water area boundary data.
[0072] Specifically, the boundary is corrected based on the boundary overlap data and combined with the historical water boundary data to obtain more accurate water boundary data. For example, for the overlapping part, the boundary is corrected in combination with the historical water boundary data. Some techniques, such as linear interpolation and curve fitting, are used to adjust the position and shape of the boundary to make it more consistent with the historical data.
[0073] The overlapping part is corrected according to the second water boundary data, such as comparing the two sets of data and adjusting the first water boundary data to make it consistent or close to the second water boundary data. For example, the overlapping part of the first water boundary data is adjusted to be consistent with the second water boundary data by using interpolation or curve fitting technology, which is completed by mathematical modeling or geographic information system software. Alternatively, according to the shape, direction and length of the second water boundary data, the first water boundary data is partially adjusted to make it closer to the second water boundary data.
[0074] In the present invention, the boundary of the water area is extracted by the main data of the water area, and the boundary information of the water area can be accurately obtained to ensure the accuracy and reliability of subsequent processing. The water boundary is extracted by using hydrodynamic simulation data, which can take into account the dynamics and changes of water flow, so as to more accurately depict the water boundary. By processing the boundary overlapping data, the boundary information of different data sources can be fused to improve the integrity and accuracy of the boundary data. By correcting the boundary data, the water boundary can be further improved and corrected according to the evolution process and historical data of the water boundary to ensure that it is more in line with the actual situation. Comprehensively considering multiple data sources and historical evolution of the water boundary, the credibility and reliability of the water boundary data can be improved, and more reliable data support can be provided for subsequent water management and planning. Through boundary comparison, fusion and correction, the boundary error and uncertainty between different data sources can be reduced, the consistency and stability of the water boundary data can be improved, and more reliable basic data can be provided for related decision-making and application. Traditional methods often only use one data source or method for boundary extraction, and cannot fully obtain the boundary information of the water area. For example, the satellite image-based method is affected by weather conditions, cloud cover, etc. and cannot obtain clear boundary information, while the hydrological data-based method ignores the impact of important factors such as topography on the boundary. The present invention uses the main data of the water area and the hydrodynamic simulation data combined with the image data to extract the boundary, making full use of the information of multiple data sources to improve the accuracy and completeness of the boundary extraction.
[0075] Optionally, performing boundary data fusion on the boundary comparison data corresponding to the boundary overlap data to obtain water area boundary data includes:
[0076] S1351, obtaining historical boundary data;
[0077] Specifically, previous water boundary data is obtained through historical records, satellite images or other reliable data sources as a reference.
[0078] S1352, performing boundary fusion according to the historical boundary data and the boundary comparison data corresponding to the boundary overlap data to obtain first water area boundary data;
[0079] Specifically, the boundary comparison data corresponding to the historical boundary data and the boundary overlap data are combined to merge and correct the boundary to obtain the first water area boundary data. For example, for the boundary overlap part, the average value or weighted average value method is used to merge the two boundaries to balance the contribution of the historical boundary data and the boundary overlap data.
[0080] S1353, performing sediment particle movement analysis according to the water area hydrodynamic simulation data to obtain sediment particle movement data;
[0081] Specifically, the movement of sediment particles in the water area is analyzed and simulated by numerical simulation methods or experimental tests using hydrodynamic simulation data to obtain sediment particle movement data.

[0083] Specifically, the boundary data is evolved according to the movement data of the sediment particles to obtain the boundary evolution data, and the boundary data is weighted and fused according to the boundary evolution data and the boundary comparison data to obtain the second water area boundary data. The evolution of the water area boundary is analyzed using the sediment particle movement data.

By performing time series processing and convolution calculation on the historical sediment component associated data, the time series characteristics of the sediment components can be comprehensively considered, and the change trend and periodic change between the sediment components can be captured, so as to more accurately predict the change trend of water quality. The application of the self-attention calculation step can effectively extract the key information and mutual influence degree in the sediment component associated data, which is helpful to identify the sediment components that have the greatest impact on water quality changes, thereby optimizing the modeling process of the water quality change trend prediction model.
