Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration, and in particular to a construction method and system for an ecological restoration structure for a slope of a pumped-storage power station. Background Art

[0002] my country is a country with abundant water resources. Using abundant water resources to generate electricity is a common way for pumped-storage power stations to utilize water resources. The construction of pumped-storage power stations usually involves a large amount of excavation and rock processing, which will cause certain damage to the surrounding environment. Therefore, effective ecological restoration measures are needed to restore and improve the ecological environment of these areas.

[0003] The ecological restoration construction of the pumped-storage power station slope requires targeted adjustments to the ecological restoration structure construction according to different slope environmental conditions. As technical personnel in related fields have refined their research on slope ecological restoration, adaptive adjustments to the vegetation planting methods in ecological restoration based on the soil conditions of different local areas on the slope have become an urgent problem to be solved in current slope ecological restoration technology.

[0004] For example, China's patent application publication number: CN116290018A, the invention discloses a slope protection method for ecological restoration of rock slopes. The invention measures the slope of the rock slope, and after obtaining the point cloud data of the rock slope, downsamples the point cloud data. Under the premise of minimal impact on the accuracy, the amount of data is greatly reduced, so that the subsequent data processing and calculation amount are greatly reduced, which can improve the calculation speed of the slope, and the noise reduction processing of the downsampled point cloud data can effectively eliminate the noise points that will affect the calculation results, thereby improving the accuracy of the rock slope section slope measurement method.

[0005] The prior art still has the following problems:

[0006] The existing technology does not take into account the differences in binding force between soil particles caused by the complex geological conditions of the slope, and cannot adaptively adjust the vegetation planting strategy for ecological restoration according to the differences in binding force of soil particles. Summary of the invention

[0007] To this end, the present invention provides a method and system for constructing an ecological restoration structure for a pumped storage power station slope, so as to overcome the problem that the prior art cannot characterize the internal binding force of soil particles based on the dust phenomenon of slope soil particles, and cannot jointly analyze sandy soil areas with poor soil particle binding force.

[0008] To achieve the above object, the present invention provides a method for constructing a pumped storage power station slope ecological restoration structure, comprising:

[0009] Acquire a soil surface image of the slope, and divide the soil surface image into a plurality of soil surface sub-areas;

[0010] Obtaining the particle concentration corresponding to each soil surface sub-area under different environmental wind speeds, drawing a concentration variation curve of the particle concentration with wind speed, and determining whether the current soil surface sub-area is a malignant ecological characteristic sub-area based on the slope of the concentration variation curve;

[0011] Determine the interval distance between the malignant ecological characteristic sub-regions based on the position information of each malignant ecological characteristic sub-region, and determine the malignant ecological impact area according to the interval distance;

[0012] Wherein, the location information includes the location coordinates of each malignant ecological characteristic sub-region, and the malignant ecological impact region includes a number of soil surface sub-regions;

[0013] Based on the concentration change curves corresponding to each soil surface sub-area in the malicious ecological impact area, the difference in particulate matter concentration under different ambient wind speeds is determined and recorded, the soil particle binding difference characterization value is calculated, and the vegetation planting depth for ecological restoration of the malicious ecological impact area is adjusted based on the soil particle binding difference characterization value.

[0014] Furthermore, the step of drawing a concentration variation curve includes:

[0015] A rectangular coordinate system is established with particle concentration as the vertical axis and wind speed as the horizontal axis;

[0016] Determine a number of data points in the rectangular coordinate system according to the particle concentrations corresponding to the soil surface sub-areas at different ambient wind speeds;

[0017] A curve obtained by connecting several data points is determined as the concentration change curve.

[0018] Furthermore, the process of determining whether the current soil surface sub-region is a sub-region with malignant ecological characteristics includes:

[0019] Determining a maximum slope value of the concentration change curve, and comparing the maximum slope value with a preset slope threshold value;

[0020] If the maximum slope value is greater than the slope threshold, the current soil surface sub-region is determined to be a sub-region with malignant ecological characteristics.

[0021] Furthermore, the process of determining the location information of the sub-region with the malignant ecological characteristics includes:

[0022] A rectangular coordinate system is established with any point in the soil surface image as the origin, the coordinates of the center point of each malignant ecological characteristic sub-region in the rectangular coordinate system are determined, and the coordinates are determined as the position coordinates of the malignant ecological characteristic sub-region.

[0023] Furthermore, the process of determining the adverse ecological impact area includes:

[0024] Calculating the interval distance between the malignant ecological characteristic sub-regions based on the position coordinates of each malignant ecological characteristic sub-region, and comparing the interval distance with a preset interval distance threshold;

[0025] If the interval distance is less than the interval distance threshold, the area consisting of two malignant ecological characteristic sub-areas corresponding to the interval distance and several soil surface sub-areas between the two malignant ecological characteristic sub-areas is determined as the malignant ecological impact area.

[0026] Further, the steps of determining and recording the difference in particle concentration under different ambient wind speeds include:

[0027] Obtaining concentration variation curves corresponding to each soil surface sub-area in the malignant ecological impact area;

[0028] Determine the maximum difference in particle concentration between different concentration change curves under the same ambient wind speed;

[0029] The maximum difference amounts corresponding to several ambient wind speeds are recorded as the difference amounts of the particle concentrations under different ambient wind speeds.

[0030] Furthermore, the soil particle binding difference characterization value is calculated based on the difference in particle concentration under different ambient wind speeds and a preset reference value for the difference in particle concentration.

[0031] Furthermore, the process of adjusting the planting depth of vegetation for ecological restoration of the area with adverse ecological impact includes:

[0032] The vegetation planting depth for ecological restoration of the vicious ecological impact area is positively correlated with the soil particle binding difference characterization value.

[0033] Furthermore, the present invention also provides a construction system for a pumped storage power station slope ecological restoration structure, comprising:

[0034] An information acquisition module, comprising an image unit for acquiring a soil surface image of a slope and dividing the soil surface image into a plurality of soil surface sub-areas, a wind speed acquisition unit for acquiring an ambient wind speed, and a soil dust detection unit for acquiring a particle concentration;

[0035] An information integration module, which is connected to the information acquisition module, and is used to draw a concentration variation curve of the particle concentration with wind speed and determine whether the current soil surface sub-area is a malignant ecological characteristic sub-area;

[0036] A feature aggregation module, which is connected to the information integration module, and is used to determine the interval distance between the sub-regions of malignant ecological features and determine the malignant ecological impact area;

[0037] The restoration and construction adjustment module is connected to the information integration module to calculate the soil particle binding difference characterization value and adjust the vegetation planting depth for ecological restoration of the area with adverse ecological impact.

[0038] Furthermore, the soil dust detection unit pre-establishes an association relationship with the soil surface sub-area, and the particle concentration obtained by the soil dust detection unit is determined as the particle concentration of the corresponding soil surface sub-area.

[0039] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention divides the soil surface image of the slope into several soil surface sub-areas, and determines whether the current soil surface sub-area is a malignant ecological characteristic sub-area by drawing the concentration change curve of the particle concentration corresponding to each soil surface sub-area under different ambient wind speeds versus wind speed. The malignant ecological impact area is determined by the interval distance between the malignant ecological characteristic sub-areas, and the vegetation planting depth for ecological restoration of the malignant ecological impact area is adjusted by calculating the soil particle binding difference characterization value. Furthermore, it is realized by characterizing the internal binding force of the soil particles according to the dust phenomenon of the slope soil particles, and by jointly analyzing the sandy soil areas with poor soil particle binding force, the vegetation planting strategy for the sandy soil areas is adjusted, thereby improving the effectiveness of ecological restoration for the slope ecological scene.

[0040] In particular, the present invention obtains the particle concentration corresponding to each soil surface sub-area under different ambient wind speeds, and draws a concentration change curve of the particle concentration with wind speed. Those skilled in the art can understand that pumped storage power stations are often built in mountainous areas with relatively complex soil topography, and the soil state of the slopes formed is changeable. The binding force of soil particles is an important manifestation of the soil state. The worse the binding force of soil particles, the more obvious the dust phenomenon under the influence of ambient wind. The present invention can clearly characterize the binding force of soil particles in each soil surface sub-area by drawing the concentration change curve of the particle concentration corresponding to each soil surface sub-area under different ambient wind speeds with wind speed, and further, realizes the characterization of the internal binding force of soil particles according to the dust phenomenon of slope soil particles, and improves the effectiveness of ecological restoration for slope ecological scenarios.

[0041] In particular, the present invention determines whether the current soil surface sub-region is a vicious ecological characteristic sub-region according to the slope of the concentration change curve. In the actual pumped storage power station slope environment, the stronger the binding force of the soil particles on the slope, the more limited the degree of change in the dust phenomenon caused by the environmental wind. On the contrary, the worse the binding force of the soil particles on the slope, the more drastic the degree of change in the dust phenomenon caused by the environmental wind. A larger environmental wind speed can cause sand with poor binding force of soil particles to produce obvious dust phenomenon, that is, the higher the concentration of particulate matter. It can be understood by those skilled in the art that the binding force of soil particles affects the soil structure and water holding capacity, and affects the growth of vegetation roots. Therefore, the area with poor binding force of soil particles can be determined as a vicious ecological characteristic sub-region, which improves the effectiveness of ecological restoration for slope ecological scenarios.

[0042] In particular, the present invention determines the vicious ecological impact area through the spacing distance between the vicious ecological characteristic sub-areas. In the actual pumped-storage power station slope environment, the vicious ecological characteristic sub-areas with a short spacing distance have poor soil particle binding force in the area, which makes the soil particles easily affected by the environmental wind, causing the soil particles to be irregularly scattered and affect the surface soil of the surrounding area. The present invention determines the vicious ecological characteristic sub-areas with a spacing distance between the vicious ecological characteristic sub-areas less than a preset threshold and the soil surface sub-areas between the spacing distances as the areas affected by the soil particle dispersion, i.e., the vicious ecological impact areas. Furthermore, it realizes the joint analysis of the sandy soil areas with poor soil particle binding force, thereby improving the effectiveness of ecological restoration for the slope ecological scene.

[0043] In particular, the present invention adjusts the vegetation planting depth for ecological restoration in the area with vicious ecological impact by calculating the soil particle binding difference characterization value. Those skilled in the art can understand that the greater the difference in particle concentration under different environmental wind speeds corresponding to the concentration change curves of each soil surface sub-area in the area with vicious ecological impact, the greater the difference in soil particle binding force characterizing each soil surface sub-area in the area with vicious ecological impact, that is, the degree of soil desertification in each soil surface sub-area is quite different. The sandy soil particles accumulate in the soil surface layer, and the soil structure becomes loose, which is easily blown away or washed away by the wind, making it difficult for vegetation to survive and reproduce in such an environment. By deepening the vegetation planting depth, the roots of the vegetation are placed in the soil layer with a stable soil structure, thereby reducing the impact of sandy soil particles on vegetation growth. Furthermore, the vegetation planting strategy is adjusted for sandy soil areas with poor binding force between soil particles, thereby improving the effectiveness of ecological restoration for slope ecological scenarios.

[0054] See also Figure 1 As shown, it is a step diagram of a method for constructing a pumped storage power station slope ecological restoration structure according to an embodiment of the present invention. A method for constructing a pumped storage power station slope ecological restoration structure according to the present invention comprises:

[0055] Step S100, obtaining a soil surface image of the slope, and dividing the soil surface image into a plurality of soil surface sub-areas;

[0056] Step S200, obtaining the particle concentration corresponding to each soil surface sub-area under different environmental wind speeds, drawing a concentration variation curve of the particle concentration with wind speed, and determining whether the current soil surface sub-area is a malignant ecological characteristic sub-area based on the slope of the concentration variation curve;

[0057] Step S300, determining the interval distance between the malignant ecological characteristic sub-regions based on the position information of each malignant ecological characteristic sub-region, and determining the malignant ecological impact area according to the interval distance;

[0058] Wherein, the location information includes the location coordinates of each malignant ecological characteristic sub-region, and the malignant ecological impact region includes a number of soil surface sub-regions;

[0059] Step S400, based on the concentration change curves corresponding to each soil surface sub-area in the malicious ecological impact area, determine and record the difference in particulate matter concentration under different ambient wind speeds, calculate the soil particle binding difference characterization value, and adjust the vegetation planting depth for ecological restoration of the malicious ecological impact area based on the soil particle binding difference characterization value.

[0060] Specifically, in the embodiment of the present invention, the particulate matter concentration refers to the PM10 concentration.

[0061] Specifically, the steps of drawing a concentration change curve include:

[0062] Step S201, establishing a rectangular coordinate system with particle concentration as the vertical axis and wind speed as the horizontal axis;

[0063] Step S202, determining a number of data points in the rectangular coordinate system according to the particle concentrations corresponding to the soil surface sub-areas under different ambient wind speeds;

[0064] Step S203: determining a curve obtained by connecting a number of data points as the concentration variation curve.

[0065] Specifically, the present invention obtains the particle concentration corresponding to each soil surface sub-area under different ambient wind speeds, and draws a concentration change curve of the particle concentration with wind speed. Those skilled in the art can understand that pumped storage power stations are often built in mountainous areas with relatively complex soil topography, and the soil state of the slopes formed is changeable. The binding force of soil particles is an important manifestation of the soil state. The worse the binding force of soil particles, the more obvious the dust phenomenon under the influence of ambient wind. The present invention draws a concentration change curve of the particle concentration corresponding to each soil surface sub-area under different ambient wind speeds with wind speed, so as to clearly characterize the binding force of soil particles in each soil surface sub-area, thereby realizing the characterization of the internal binding force of soil particles according to the dust phenomenon of slope soil particles, thereby improving the effectiveness of ecological restoration for slope ecological scenarios.

[0066] Specifically, see Figure 2 As shown, it is a logic flow chart of determining whether the current soil surface sub-region is a sub-region with malignant ecological characteristics according to an embodiment of the present invention. The process of determining whether the current soil surface sub-region is a sub-region with malignant ecological characteristics includes:

[0067] Determine the maximum value k of the slope of the concentration change curve max , the maximum slope k max Compare with the preset slope threshold k0;

[0068] If the maximum slope k max If the slope is less than or equal to the slope threshold k0, it is determined that the current soil surface sub-region is not a sub-region with malignant ecological characteristics;

[0069] If the maximum slope k max If the slope is greater than the slope threshold k0, the current soil surface sub-region is determined to be a sub-region with malignant ecological characteristics.

[0070] In an embodiment of the present invention, the preset slope threshold k0 is based on a pre-calculated result, and the corresponding slope values ​​of several data points on the concentration change curve corresponding to several soil surface sub-areas are pre-determined, and the average value of the slope values ​​corresponding to the several data points is determined as the preset slope threshold k0.

[0071] Specifically, the present invention determines whether the current soil surface sub-area is a vicious ecological characteristic sub-area according to the slope of the concentration change curve. In the actual slope environment of the pumped-storage power station, the stronger the binding force of the soil particles on the slope, the more limited the degree of change in the dust phenomenon caused by the environmental wind. On the contrary, the worse the binding force of the soil particles on the slope, the more drastic the degree of change in the dust phenomenon caused by the environmental wind. A larger environmental wind speed can cause sand with poor binding force of soil particles to produce obvious dust phenomenon, that is, the higher the concentration of particulate matter. It can be understood by those skilled in the art that the binding force of soil particles affects the soil structure and water holding capacity, and affects the growth of vegetation roots. Therefore, the area with poor binding force of soil particles can be determined as a vicious ecological characteristic sub-area, which improves the effectiveness of ecological restoration for slope ecological scenarios.

[0072] Specifically, the process of determining the location information of the sub-regions of malignant ecological characteristics includes:

[0073] A rectangular coordinate system is established with any point in the soil surface image as the origin, the coordinates of the center point of each malignant ecological characteristic sub-region in the rectangular coordinate system are determined, and the coordinates are determined as the position coordinates of the malignant ecological characteristic sub-region.

[0074] Specifically, the process of identifying the areas of adverse ecological impact includes:

[0075] Calculating the interval distance d between the malignant ecological characteristic sub-regions based on the position coordinates of each malignant ecological characteristic sub-region, and comparing the interval distance d with a preset interval distance threshold d0;

[0076] If the interval distance d is greater than or equal to the interval distance threshold d0, the area consisting of the two malignant ecological characteristic sub-areas corresponding to the interval distance and the several soil surface sub-areas between the two malignant ecological characteristic sub-areas will not be determined as the malignant ecological impact area;

[0077] If the interval distance d is less than the interval distance threshold d0, the area consisting of the two malignant ecological characteristic sub-areas corresponding to the interval distance and several soil surface sub-areas between the two malignant ecological characteristic sub-areas is determined as the malignant ecological impact area.

[0078] In an embodiment of the present invention, the value of the interval distance threshold d0 is determined based on the minimum length value L1 and the minimum width value L2 of the soil surface sub-area, d0=δ×(L1+L2) / 2, δ is the interval distance threshold value factor, and the value range of δ is [2,5].

[0079] In the embodiment of the present invention, please refer to Figure 3As shown, it is a schematic diagram of the malignant ecological impact area according to an embodiment of the present invention. The interval distance d between the malignant ecological characteristic sub-areas is calculated according to the position coordinate a (Xa, Ya) of the first malignant ecological characteristic sub-area 1 and the position coordinate b (Xb, Yb) of the second malignant ecological characteristic sub-area 4. ;

[0080] If the interval distance d is less than the interval distance threshold d0, the area consisting of the first malignant ecological characteristic sub-area 1 and the second malignant ecological characteristic sub-area 4 corresponding to the interval distance and the first soil surface sub-area 2 and the second soil surface sub-area 3 between the first malignant ecological characteristic sub-area 1 and the second malignant ecological characteristic sub-area 4 are determined as the malignant ecological impact area.

[0081] Specifically, the present invention determines the vicious ecological impact area through the spacing distance between the vicious ecological characteristic sub-areas. In the actual pumped-storage power station slope environment, the vicious ecological characteristic sub-areas with a short spacing distance have poor soil particle binding force in the area, which makes the soil particles easily affected by the environmental wind, causing the soil particles to be irregularly scattered and affect the surface soil of the surrounding area. The present invention determines the vicious ecological characteristic sub-areas with a spacing distance between the vicious ecological characteristic sub-areas less than a preset threshold and the soil surface sub-areas between the spacing distances as the areas affected by the soil particle dispersion, i.e., the vicious ecological impact areas. Furthermore, it realizes the joint analysis of the sandy soil areas with poor soil particle binding force, thereby improving the effectiveness of ecological restoration for the slope ecological scene.

[0082] Specifically, see Figure 4 As shown, it is a step diagram of determining and recording the difference in particle concentration under different ambient wind speeds according to an embodiment of the present invention. The step of determining and recording the difference in particle concentration under different ambient wind speeds includes:

[0083] Step S401, obtaining the concentration change curve corresponding to each soil surface sub-area in the malicious ecological impact area;

[0084] Step S402, determining the maximum difference in particle concentration between different concentration change curves under the same ambient wind speed;

[0085] Step S403: Record the maximum difference corresponding to several ambient wind speeds as the difference in particle concentration under different ambient wind speeds.

[0086] Specifically, the soil particle binding difference characterization value is calculated based on the difference in particle concentration under different ambient wind speeds and a preset reference value for the difference in particle concentration.

[0087] The soil particle binding difference characterization value is calculated according to the following formula: ;

[0088] Wherein, C is the soil particle binding difference characterization value, C i is the difference in particle concentration under the i-th ambient wind speed, i=1, 2, 3…n, n is the number of selected ambient wind speeds, C av It is the preset reference value of the difference in particle concentration.

[0089] In the embodiment of the present invention, the difference reference value C of the particle concentration av Based on the pre-calculated result, the average value of the difference in particle concentration of the concentration change curves corresponding to several soil surface sub-areas under different ambient wind speeds is pre-determined, and the average value of the difference in particle concentration is determined as the reference value C of the difference in particle concentration av .

[0090] Specifically, the process of adjusting the planting depth of vegetation for ecological restoration of the said adverse ecological impact area includes:

[0091] The vegetation planting depth for ecological restoration of the vicious ecological impact area is positively correlated with the soil particle binding difference characterization value.

[0092] Specifically, the present invention adjusts the vegetation planting depth for ecological restoration in the area with vicious ecological impact by calculating the soil particle binding difference characterization value. Those skilled in the art can understand that the greater the difference in particle concentration under different environmental wind speeds corresponding to the concentration change curves of each soil surface sub-area in the area with vicious ecological impact, the greater the difference in soil particle binding force characterizing each soil surface sub-area in the area with vicious ecological impact, that is, the degree of soil desertification in each soil surface sub-area is quite different. The sandy soil particles accumulate in the soil surface layer, and the soil structure becomes loose, which is easily blown away or washed away by the wind, making it difficult for vegetation to survive and reproduce in such an environment. By deepening the vegetation planting depth, the roots of the vegetation are placed in the soil layer with a stable soil structure, thereby reducing the impact of sandy soil particles on vegetation growth. Furthermore, the vegetation planting strategy is adjusted for sandy soil areas with poor binding force between soil particles, thereby improving the effectiveness of ecological restoration for slope ecological scenarios.
