[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the implementation manners of this application in detail with reference to the drawings.

[0037] It should be noted that the terms "first", "second", etc. in this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of this application described here can be implemented in an order different from those illustrated or described here. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with this application. On the contrary, they are merely examples of devices and methods consistent with some aspects of this application as detailed in the appended claims.

[0038] Please refer to Figures 1 to 2As shown in the figure, the present invention provides a comprehensive evaluation method and system for water ecological protection and restoration, which includes a detection unit 1 and an evaluation unit 2 in terms of functional units. The detection unit 1 can be a virtual functional unit, which receives control instructions from the evaluation unit 2 during the working process, executes detection operations, and transmits the detection results back to the evaluation unit 2.

[0039] During the specific working process, first, the evaluation unit 2 executes step S1 to obtain multiple types of inspection items in the comprehensive evaluation process of water ecological protection and restoration, and divides them into representative inspection items and in-depth inspection items. Next, the detection unit 1 detects the inspection parameters of each water area plot for each type of representative inspection item, and concurrently transmits them to the evaluation unit 2. The evaluation unit 2 can then execute step S2 to obtain the inspection parameters of each water area plot for each type of representative inspection item respectively. Next, it can execute step S3 to obtain several plot combinations with consistent water ecology based on the inspection parameters of each water area plot for each type of representative inspection item.

[0040] Please refer to Figures 2 to 3. The inspection parameters of each type of representative inspection item for water area plots with consistent water ecology can be the same or approximate, which requires calculating and judging the approximate boundaries. Specifically, first, step S31 can be executed to obtain the inspection parameter ranges of each type of representative inspection item at each quality level in the national standard. The national standard in this solution can be the "Technical Guidelines for Evaluating the Ecological and Environmental Effects of the Implementation of Ecological Protection and Restoration Projects (Trial)", or the "Technical Guidelines for Evaluating the Implementation Effects of Major Projects for the Protection and Restoration of Important Ecosystems". Next, step S32 can be executed to select multiple water area plots as marked water area plots in all water area plots based on the inspection parameters of each water area plot for each type of inspection item and the inspection parameter ranges of each type of inspection item at each quality level in the national standard.

[0041] Please refer to Figure 4 As shown in the figure, in order to make the selected marked water area plots have broad representativeness and reduce the computational complexity of subsequent classification of water area plot combinations, first, step S321 can be executed to obtain the inspection parameter distribution ranges of all water area plots for each type of inspection item based on the inspection parameters of each water area plot for each type of inspection item. Next, step S322 can be executed to obtain all the quality levels involved in each type of inspection item for all water area plots based on the inspection parameter distribution ranges of all water area plots for each type of inspection item and the inspection parameter ranges of each type of inspection item at each quality level in the national standard. Next, step S323 can be executed to select multiple water area plots as marked water area plots in each water area plot, so that the inspection parameters of all marked water area plots for each type of inspection item are distributed among all the quality levels involved in each type of inspection item for all water area plots.

[0042] To supplement the implementation process of the above steps S321 to S323, the source code of some functional modules is provided, and corresponding explanations are given in the annotation part. To avoid the leakage of data involving trade secrets, some data that does not affect the implementation of the solution is desensitized. The same applies hereinafter.

[0046]

[0047]

[0048] This section of code implements the process of selecting and marking water area plots from all water area plots according to the parameter distribution range of inspection items and the national standard quality grade range. First, calculate the distribution range (minimum value and maximum value) of the inspection parameters of all water area plots for each inspection item. Then, filter out the eligible marked water area plots according to the quality grade range in the national standard and the inspection parameter distribution of the water area plots. Finally, the code outputs the eligible marked water area plots and displays their areas and inspection parameters.

[0049] The goal of this process is to ensure that the selected marked water area plots can cover all quality grade ranges in the inspection parameters of each inspection item, providing an accurate basis for subsequent water ecological restoration evaluation and acceptance.

[0050] Please refer to Figures 2 to 5. After selecting the representative water area plots, step S33 can be executed to group the marked water area plots and other water area plots into several consistent plot combinations according to the differences in the inspection parameters of each type of representative inspection item. Since the differences in the quality of ecological protection and restoration between different water area plots can be quantitatively calculated through the differences in the inspection parameters of each type of inspection item, when grouping the plot combinations, step S331 can be executed first to use the accumulated value of the differences in the inspection parameters of each type of inspection item between two water area plots as the evaluation difference value between the two water area plots, and calculate the evaluation difference value between each marked water area plot and each other water area plot. Next, step S332 can be executed to classify each other water area plot and the marked water area plot with the smallest rating difference value into the same plot combination.

[0051] However, the plot combinations obtained after the above round of calculation and classification may still be inconsistent internally. Therefore, it is necessary to verify whether there is consistency within the plot combinations next. Thus, the following steps can be executed: Step S333 to calculate and obtain the average inspection parameters of all water area plots in each plot combination for each type of inspection item. Next, step S334 can be executed to determine whether the water area plot with the smallest evaluation difference value between each plot combination and the average inspection parameters of all water area plots for each type of inspection item is the marked water area plot. If so, then step S335 can be executed next to determine that the current plot combination is the plot combination with consistency.

[0052] If not, then step S336 can be executed next to reselect the marked water area plot and continuously judge until the plot combination with consistency is obtained. Specifically, step S3361 can be executed. Within each plot combination, the water area plot with the smallest evaluation difference value between each plot combination and the average inspection parameters of all water area plots for each type of inspection item is used as the updated marked water area plot. Next, steps S331 to S334 can be executed to recalculate and obtain the evaluation difference value between each marked water area plot and each other water area plot based on the updated marked water area plot, and the updated plot combination is re-divided. Continuously judge whether the water area plot with the smallest evaluation difference value between the updated plot combination and the average inspection parameters of all water area plots for each type of inspection item is the marked water area plot. The consistency classification is automatically completed through a continuous iterative method.

[0053] To supplement the implementation process of the above steps S331 to S336, the source code of some functional modules is provided, and corresponding explanatory notes are given in the annotation part.

[0060]

[0061] The above code realizes the process of grouping the marked water area plots and other cultivated water area plots according to the difference in inspection parameters of each inspection item to obtain a consistent plot combination. First, the evaluation difference value between the marked water area plot and other water area plots is calculated (the accumulation of the difference in inspection parameters of each inspection item). Then, according to the magnitude of the difference value, the water area plots with the smallest difference value are assigned to the same plot combination. Next, the average inspection parameters of all water area plots within the plot combination for each inspection item are calculated, and it is determined whether to update the marked water area plot based on the average value. If it is not the marked water area plot, the water area plot with the smallest difference value is used as the new marked water area plot and continues to be updated until the conditions are met.

[0062] This algorithm can help identify highly consistent water area plot combinations, classify and update water area plots based on these combinations, and provide effective data support for the comprehensive evaluation of water area restoration.

[0063] Please continue to refer to Figures 1 to 2 As shown, the next step S4 can be executed to extract a representative water area plot within each plot combination, which can be to use the marked water area plot within each plot combination as the representative water area plot. After the detection unit 1 receives the representative water area plot and detects the inspection parameters of each representative water area plot for each type of in-depth inspection item, the evaluation unit 2 continues to obtain the inspection parameters of the marked water area plot for each type of in-depth inspection item as the inspection parameters of each water area plot within the plot combination for each type of in-depth inspection item. Finally, step S5 can be executed to comprehensively evaluate the protection and restoration effect of each water area plot based on the inspection parameters of each water area plot for each representative inspection item and in-depth inspection item. The specific evaluation process can be carried out in accordance with the "Technical Guidelines for the Evaluation of the Ecological and Environmental Effects of the Implementation of Ecological Protection and Restoration Projects (Trial)" or evaluated according to custom scoring rules.
