[0020] Figure 3 This is a structural diagram of an electronic device provided in an exemplary embodiment of this application. Detailed Implementation
[0021] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.
[0022] Figure 1 This is a schematic flowchart of a vegetation ecological maintenance method for grassland restoration on degraded slopes provided in an exemplary embodiment of this application. Figure 1 As shown, the vegetation ecological maintenance method for grassland restoration on this degraded slope includes the following steps: Step 110: Obtain ecological status indicators of the target degraded slope grassland.
[0023] The ecological status indicators include vegetation indicators, soil indicators, and environmental indicators. Vegetation indicators characterize the growth status of vegetation planted on the target degraded slope grassland, soil indicators characterize the soil condition of the target degraded slope grassland, and environmental indicators characterize the environmental condition of the area where the target degraded slope grassland is located. Specifically, this application uses multiple sensors to collect ecological status indicators of the target degraded slope grassland in real time. For example, soil moisture sensors collect soil moisture content in real time, meteorological sensors monitor rainfall, temperature, and humidity in real time, and soil erosion monitoring pins monitor soil erosion in real time.
[0024] Step 120: Determine the ecological status trend of the target degraded slope grassland based on ecological status indicators.
[0025] Among them, the ecological state trend represents the predicted ecological state of the target degraded slope grassland in the future time period. This application predicts the ecological state of the target degraded slope grassland in the future time period based on the ecological state indicators to obtain the ecological state trend, thereby predicting the ecological state of the target degraded slope grassland in advance, so as to realize early intervention and protect its ecological environment.
[0026] Step 130: Based on ecological status trends and the range of comfort indicators suitable for vegetation growth, determine the maintenance strategy for the target degraded slope grassland.
[0027] Based on ecological state trends and the range of comfort indicators suitable for vegetation growth, this application formulates a maintenance strategy for target degraded slope grasslands to ensure that vegetation on the target degraded slope grasslands grows within the range of these comfort indicators.
[0028] Step 140: Based on the maintenance strategy, carry out ecological maintenance on the target degraded slope grassland.
[0029] This application describes the ecological maintenance of target degraded slope grasslands based on a developed maintenance strategy, in order to improve their ecological condition.
[0030] Step 150: Obtain the restoration status indicators of the target degraded slope grassland after maintenance.
[0031] This application obtains ecological status indicators (restoration status indicators) of the target degraded slope grassland again after ecological maintenance to determine the effectiveness of the maintenance strategy.
[0032] Step 160: If the repair status indicators meet the preset conditions, then stop the maintenance strategy.
[0033] If the obtained restoration status indicators meet the preset conditions (i.e., the maintenance strategy achieves the expected purpose), the maintenance strategy is stopped; if the obtained restoration status indicators do not meet the preset conditions, it means that the maintenance strategy has not achieved the expected purpose. At this time, it is necessary to determine a new maintenance strategy based on the restoration status indicators in order to maintain the target degraded slope grassland again until the ecological status indicators of the target degraded slope grassland meet the preset conditions.
[0034] This application provides a vegetation ecological maintenance method for the restoration of degraded slope grasslands, which obtains ecological status indicators of the target degraded slope grassland. These ecological status indicators include vegetation indicators, soil indicators, and environmental indicators. Vegetation indicators characterize the growth status of vegetation planted on the target degraded slope grassland, soil indicators characterize the soil condition of the target degraded slope grassland, and environmental indicators characterize the environmental condition of the area where the target degraded slope grassland is located. Based on these ecological status indicators, the ecological status trend of the target degraded slope grassland is determined. This ecological status trend represents a prediction of the ecological status of the target degraded slope grassland over a future time period. Based on the ecological status trend and suitable conditions for vegetation growth... The system determines the maintenance strategy for the target degraded slope grassland by defining the comfort index range; based on the maintenance strategy, ecological maintenance is carried out on the target degraded slope grassland; the restoration status index of the target degraded slope grassland after maintenance is obtained; if the restoration status index meets the preset conditions, the maintenance strategy is stopped; by monitoring the ecological status index of the target degraded slope grassland, the ecological status trend of the target degraded slope grassland is predicted based on this, and the maintenance strategy is determined according to the ecological status trend to respond to the maintenance operation of the target degraded slope grassland in advance, thereby ensuring the vegetation survival environment of the target degraded slope grassland, improving the vegetation survival rate of the target degraded slope grassland, and thus improving the restoration effect of the degraded slope grassland.
[0035] In one embodiment, step 110 can be implemented as follows: acquiring a three-dimensional geomorphic image of the target degraded slope grassland; identifying the three-dimensional geomorphic image to obtain a vegetation image on the target degraded slope grassland; and determining vegetation indicators of the target degraded slope grassland based on the three-dimensional geomorphic image and the vegetation image.
[0036] This application can use equipment such as drones to periodically capture three-dimensional geomorphological images of the target degraded slope grassland, and by identifying the three-dimensional geomorphological images, obtain the vegetation images on the target degraded slope grassland, thereby determining the vegetation indicators of the target degraded slope grassland and obtaining the growth status of the vegetation on the target degraded slope grassland.
[0037] In one embodiment, step 110 can be implemented as follows: binarize the three-dimensional terrain image to obtain a binarized image; perform boundary diffusion on the center pixel of the binarized image to divide it into multiple vegetation images.
[0038] To improve the accuracy of image recognition, this application first binarizes the 3D terrain image based on the pixel values of vegetation to obtain a binarized image. Then, it performs boundary diffusion on the binarized image to divide it into multiple vegetation images. Specifically, this application can select any vegetation pixel in the binarized image as the starting pixel and perform boundary diffusion with the starting pixel as the center pixel. When the pixel values of its surrounding pixels are the same as its starting pixel (there are only two types of pixel values in the binarized image), the surrounding pixels are merged into its neighborhood and diffusion continues until pixels with different pixel values appear. Then, the expansion stops to determine the vegetation image corresponding to the vegetation pixel. Then, the above operation is repeated by selecting undetermined vegetation pixels as new starting pixels until all vegetation pixels are divided into the corresponding vegetation images, and then the division of vegetation images ends.
[0039] In one embodiment, step 110 can be implemented by converting the three-dimensional landform image and vegetation image into two-dimensional planar maps to obtain two-dimensional landform maps and two-dimensional vegetation maps respectively; and calculating the vegetation coverage of the target degraded slope grassland based on the two-dimensional landform maps and two-dimensional vegetation maps.
[0040] To simplify the calculation, this application converts the three-dimensional landform image and vegetation image into a two-dimensional planar map, thereby obtaining a two-dimensional landform map and a two-dimensional vegetation map, and calculates the proportion of the two-dimensional vegetation map in the two-dimensional landform map to obtain the vegetation coverage of the target degraded slope grassland.
[0041] In one embodiment, step 110 can be implemented as follows: based on the vegetation image, determine the vegetation height of each plant in the target degraded slope grassland; based on the vegetation height of all plants and their corresponding locations, divide the target degraded slope grassland into at least one vegetation zone; and based on the vegetation height of the plants in each vegetation zone, determine the vegetation height of the vegetation zone.
[0042] This application identifies the vegetation height of each plant in the target degraded slope grassland by recognizing vegetation images. Based on the vegetation height and corresponding location of all vegetation, the target degraded slope grassland is divided into at least one vegetation zone, where the vegetation height in each vegetation zone is relatively uniform, reflecting the growth status of the vegetation in that zone. Furthermore, for each vegetation zone, the average height of all vegetation heights is calculated as the vegetation height of that zone, thereby determining the vegetation height of each vegetation zone and enabling the adoption of corresponding maintenance strategies for different vegetation zones.
[0043] In one embodiment, step 120 can be implemented by predicting the ecological state trend of the target degraded slope grassland based on vegetation indicators, soil indicators, environmental indicators and comfort indicator ranges.
[0044] This application predicts the ecological status trend of target degraded slope grassland based on vegetation indicators, soil indicators, environmental indicators, and comfort index ranges. Among them, the comfort index range for soil organic matter content is [30, ∞), the comfort index range for soil moisture content is [15%, ∞), the comfort index range for soil erosion modulus is (-∞, 500], the comfort index range for soil pH is 6.5-8.5, the comfort index range for soil erosion reduction rate is [70%, ∞), and the comfort index range for surface runoff coefficient is (-∞, 0.3).
[0045] In one embodiment, step 120 can be implemented by predicting the ecological state trend of the target degraded slope grassland based on the change curves of vegetation indicators, soil indicators, and environmental indicators of the target degraded slope grassland.
[0046] This application periodically collects vegetation, soil, and environmental indicators of target degraded grassland slopes. Based on the collected values, it performs interpolation and fitting to obtain change curves for these indicators. According to the correspondence between these curves, the ecological state trend of the target degraded grassland slopes is predicted. Optionally, this application can input the change curves of vegetation, soil, and environmental indicators into a neural network model to obtain a relationship model between these curves. Furthermore, it combines this relationship model with soil and environmental indicators for future time periods to predict corresponding vegetation indicators. This application can also use this relationship model to adjust soil or environmental indicators to generate corresponding vegetation indicators, and use the optimal soil and environmental indicators corresponding to the vegetation indicators as key parameters to guide subsequent maintenance strategies.
[0047] In one embodiment, step 130 can be implemented as follows: if there is an indicator in the ecological state trend that is outside the comfort index range, then a maintenance strategy for the target degraded slope grassland is determined based on the indicator so as to control the indicator within the corresponding comfort index range.
[0048] If the predicted ecological state trend contains an indicator that is outside the comfort index range, it indicates that the vegetation growth status on the target degraded slope grassland is not good according to the current growth environment. At this time, the maintenance strategy for the target degraded slope grassland should be determined based on the indicator to control the indicator within the corresponding comfort index range, thereby achieving early intervention to improve the vegetation growth environment and growth status.
[0049] In one embodiment, step 160 can be implemented as follows: if the repair status index is within the comfort index range and the difference between the repair status index and the upper and lower limits of the comfort index range is greater than a preset difference threshold, then the maintenance strategy is stopped.
[0050] This application stipulates that after maintaining the target degraded slope grassland using a maintenance strategy, if the restored state index returns to the comfort index range, and the difference between the upper and lower limits of the restored state index and the comfort index range is greater than a preset difference threshold, it indicates that the restored state index is some distance from the upper and lower limits. At this point, the maintenance strategy can be stopped, and the target degraded slope grassland can be continuously monitored. Specifically, irrigation is initiated when soil moisture is less than 15% and weather forecast data indicates no rainfall in the near future. The irrigation area, irrigation volume, and irrigation method (drip irrigation or spraying) are determined based on the vegetation water requirement model (vegetation water requirement determined based on vegetation and soil indicators). When the vegetation height (after a period of planting) is less than 15cm, the amount of organic fertilizer applied is determined based on soil nutrient monitoring data and the vegetation growth model (soil nutrient requirement determined based on the correspondence between soil nutrients and vegetation height). Reseeding is initiated when vegetation coverage is less than 60%.

(See diagram below.) Figure 2 As shown, the vegetation ecological maintenance system 20 for degraded slope grassland restoration includes: an ecological index acquisition module 21, used to acquire ecological status indicators of the target degraded slope grassland; wherein, the ecological status indicators include: vegetation indicators, soil indicators, and environmental indicators, whereby vegetation indicators characterize the growth status of vegetation planted on the target degraded slope grassland, soil indicators characterize the soil status of the target degraded slope grassland, and environmental indicators characterize the environmental status of the area where the target degraded slope grassland is located; an ecological trend determination module 22, used to determine the ecological status trend of the target degraded slope grassland based on the ecological status indicators; wherein, the ecological status trend characterizes the predicted result of the ecological status of the target degraded slope grassland in the future time period; a maintenance strategy determination module 23, used to determine the maintenance strategy of the target degraded slope grassland based on the ecological status trend and the range of comfortable indicators suitable for vegetation growth; an ecological maintenance execution module 24, used to perform ecological maintenance on the target degraded slope grassland based on the maintenance strategy; a restoration status acquisition module 25, used to acquire the restoration status indicators of the target degraded slope grassland after maintenance; and a maintenance strategy stop module 26, used to stop the maintenance strategy if the restoration status indicators meet preset conditions.
