Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration, and particularly to an ecological restoration method and system based on power station construction. Background Art

[0002] Power station construction requires construction activities such as site leveling, earthwork excavation and filling, material stacking, and cable trench excavation. These activities will inevitably damage the soil environment, interfere with the normal growth of vegetation, and cause or exacerbate soil erosion. Especially in the peripheral areas outside the power station construction area, vegetation is usually severely damaged due to power station construction, leading to ecological imbalance. For example, in the desert grassland ecosystem, the vegetation is mostly low and short shrub desert vegetation. Once impacted and damaged by construction activities, the natural recovery of vegetation is difficult, which is likely to exacerbate desertification and even trigger the risk of sandification.

[0003] Existing ecological restoration solutions usually rely on artificial planning to increase the vegetation coverage in the target area. However, they cannot conduct targeted ecological restoration for the ecological problems caused by power station construction, thus unable to ensure that the restored ecology can maintain the state level before power station construction. Seriously, it may even damage the local unique vegetation and animal habitats, resulting in a reduction in biodiversity.

[0004] In summary, the ecological problems and impacts that may be caused after power station construction are multi-faceted. It is very necessary to conduct a comprehensive environmental impact assessment before power station construction and take corresponding environmental protection measures and ecological restoration solutions. Currently, there is no technical solution that can solve the above technical problems, nor an ecological restoration method and system based on power station construction. Summary of the Invention

[0047] Figure 3 is a schematic structural diagram of the ecological restoration system based on power station construction provided by the present invention;

[0048] Figure 4 It is a schematic structural diagram of the electronic device provided by the present invention. Specific embodiments

[0049] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0050] Figure 1 It is a schematic flowchart of the ecological restoration method based on power station construction provided by the present invention. The ecological restoration method based on power station construction includes:

[0051] Step 101: In the pre-construction stage of the power station, obtain the original vegetation coverage rate corresponding to the construction area where the power station is located, determine the area to be restored according to the construction area. The area to be restored is the outer area that does not include the construction area determined based on the ecological restoration area centered on the construction area.

[0052] Step 102: Divide the area to be restored into all outer sub-areas. For each outer sub-area, determine the target vegetation type and target vegetation coverage rate corresponding to the outer sub-area, determine the restoration coefficient corresponding to the outer sub-area according to the original vegetation coverage rate, and determine the expected vegetation coverage rate corresponding to the outer sub-area according to the restoration coefficient and the target vegetation coverage rate.

[0053] Step 103: In the post-construction stage of the power station, traverse each outer sub-area, obtain the current vegetation coverage rate corresponding to each outer sub-area. When the current vegetation coverage rate corresponding to any outer sub-area is less than the expected vegetation coverage rate, generate an indication instruction corresponding to the outer sub-area. The indication instruction is used to indicate planting the target vegetation corresponding to the target vegetation type in the outer sub-area.

[0054] In step 101, first, a drone is used to capture remote sensing image data of the construction area where the power station is located. The remote sensing image data can then be processed by the normalized difference vegetation index (NDVI) to determine the original vegetation coverage rate of the area. According to the construction area, an ecological restoration area is preset in the present invention. The ecological restoration area is a range that expands outward with the construction area as the center. Then, the construction area itself is excluded from this ecological restoration area, and the remaining outer area is determined as the area to be restored. The determination of the area to be restored takes into account the ecological impact of the construction area, ensuring the pertinence and effectiveness of the ecological restoration work.

[0055] Optionally, the determination of the area to be restored according to the construction area includes:

[0056] Determine the minimum bounding rectangle according to the construction area, and determine the ecological restoration area according to the minimum bounding rectangle and a preset magnification factor;

[0057] Determine the area outside the construction area in the ecological restoration area as the area to be restored, or determine the area outside the minimum bounding rectangle in the ecological restoration area as the area to be restored.

[0058] As Figure 2 shown, Figure 2 is a schematic diagram of area division of the ecological restoration method based on power station construction provided by the present invention. First, based on the geographical coordinates or remote sensing image data of the construction area, the actual boundary of the construction area is identified, and then the minimum bounding rectangle that can completely contain the construction area, that is, the minimum bounding rectangle, is calculated. The minimum bounding rectangle will be used as the basis for determining the ecological restoration area; then, according to the preset magnification factor, the size of the minimum bounding rectangle is enlarged accordingly to determine the range of the ecological restoration area. The selection of the magnification factor should be based on factors such as the assessment of ecological impact, the setting of restoration goals, and the availability of restoration resources. The present invention provides two methods for determining the area to be restored:

[0059] Method 1: Determine the area to be restored as the area in the ecological restoration area excluding the construction area. Method 1 may need to consider the division problem caused by the irregularity of the construction area when determining all the outer sub-areas. However, if equal division is not considered, Method 1 will make the ecological restoration more accurate. Method 2: Determine the area to be restored as the area in the ecological restoration area excluding the maximum circumscribed rectangle. Method 2 actually expands an area determined by the magnification factor further outward on the basis of the maximum circumscribed rectangle as the area to be restored. Therefore, when equally dividing all the subsequent outer sub-areas, it will be easier to implement compared to Solution 1. By adjusting the preset magnification factor, the present invention can flexibly control the scope of the ecological restoration area, so as to adapt to different ecological restoration requirements and resource conditions. Based on the determination method of the maximum circumscribed rectangle, it can ensure that the ecological restoration area covers at least the construction area and its surrounding areas that may be affected, improving the accuracy of ecological restoration. The present invention also provides two methods for determining the area to be restored, and the most suitable method can be selected according to specific circumstances to adapt to different ecological restoration scenarios and constraint conditions.

[0060] Optionally, obtaining the original vegetation coverage rate corresponding to the construction area where the power station is located includes:

[0061] Obtain the remote sensing image data corresponding to the construction area, and the remote sensing image data is taken by a drone at a first preset height;

[0062] Process the remote sensing image data using the normalized difference vegetation index to determine the original vegetation coverage rate.

[0063] Optionally, use a drone to take pictures of the construction area where the power station is located at a first preset height to obtain the remote sensing image data of the area. The first preset height should be set to a suitable height that can clearly capture the ground vegetation characteristics but will not cause image distortion or incomplete coverage due to too low a height. When the drone takes pictures, a certain flight path and shooting frequency can be set to ensure that the entire construction area is evenly and comprehensively covered. The normalized difference vegetation index (NDVI) is a remote sensing index used to evaluate vegetation coverage and vegetation health status. It is based on the difference in reflectance between the red and near-infrared bands of vegetation and is obtained by calculating the ratio of the difference between the reflectances of these two bands to the sum of the reflectances. Input the obtained remote sensing image data into the NDVI processing software, and the software will calculate the corresponding NDVI value according to the red and near-infrared band information of each pixel in the image. By analyzing the NDVI value distribution of the entire construction area, the original vegetation coverage rate of the area can be determined. Generally, areas with higher NDVI values indicate better vegetation coverage, while areas with lower NDVI values indicate poorer vegetation coverage or more bare soil.

[0064] Optionally, in addition to the method of evaluating vegetation cover using the normalized difference vegetation index, several points can be randomly or systematically placed within the construction area where the power station is located, and then vertical downward observations are made at each point to record the situation of the ground covered by vegetation. The vegetation coverage rate is equal to the percentage of the number of points covered by vegetation to the total number of points. It is also possible to establish quadrats of a fixed size within the construction area where the power station is located, and then record the area of the ground covered by vegetation in each quadrat. The vegetation coverage rate is equal to the percentage of the area covered by vegetation to the total area of the quadrats.

[0065] In step 102, as Figure 2 shown, the area to be repaired is divided into multiple peripheral sub-areas for more targeted ecological restoration management. For each peripheral sub-area, image data is captured by a drone at a second preset height and input into a preset vegetation type prediction model to obtain the predicted target vegetation types. At the same time, the image data of the area is processed through NDVI to determine the target vegetation coverage rate. Based on the original vegetation coverage rate and other preset coefficients (such as environmental, climate, and other factors), the restoration coefficient of each peripheral sub-area is determined. Then, by combining the target vegetation coverage rate and the restoration coefficient, the expected vegetation coverage rate of each peripheral sub-area is calculated. In such an embodiment, since the target vegetation coverage rates of different peripheral sub-areas will be different and the target vegetation types will also be different, the present invention makes targeted treatments for each peripheral sub-area, and the restoration coefficients corresponding to each peripheral sub-area are all different, and the expected vegetation coverage rates of each peripheral sub-area are also different.

[0066] Optionally, determining the target vegetation types and target vegetation coverage rate corresponding to the peripheral sub-areas includes:

[0067] Obtaining the image data corresponding to the peripheral sub-area, where the image data is captured by a drone at a second preset height, and the second preset height is less than the first preset height;

[0068] Inputting the image data into a preset vegetation type prediction model to obtain one or more vegetation types output by the preset vegetation type prediction model, and determining the target vegetation types according to the one or more vegetation types. The preset vegetation type prediction model is determined after being trained based on all sample image data and the vegetation type labels marked in each sample image data;

[0069] Obtaining the sub-area image data corresponding to the peripheral sub-area, processing the sub-area image data using the normalized difference vegetation index, and determining the target vegetation coverage rate. The sub-area image data is captured by a drone at the first preset height.

[0070] Optionally, a drone is used to photograph the peripheral sub-region at a second preset altitude to obtain image data of the region. The second preset altitude is set to be less than the first preset altitude, which is to more finely capture the detailed features of ground vegetation and improve the accuracy of vegetation species identification. When the drone takes pictures, it is also necessary to plan the flight path and shooting frequency to ensure that the entire peripheral sub-region is fully covered. The obtained image data is input into a preset vegetation species prediction model. The preset vegetation species prediction model is trained based on a large number of sample image data and their corresponding vegetation species labels, and can automatically identify the vegetation species in the image. The model outputs one or more vegetation species as the prediction result. Finally, according to the prediction result, the target vegetation species of the peripheral sub-region can be determined. Using the preset vegetation species prediction model for vegetation species identification realizes automation and intelligence, and reduces the errors caused by manual intervention and subjective judgment.

[0071] Optionally, in order to calculate the target vegetation coverage rate, it is necessary to obtain the sub-region image data of each peripheral sub-region. Correspondingly, the sub-region image data is taken at the first preset altitude. By using NDVI to process the sub-region image data, the vegetation coverage of each peripheral sub-region can be determined, that is, by using the normalized difference vegetation index to process the sub-region image data, the target vegetation coverage rate corresponding to each peripheral sub-region before the construction of the power station is determined.

[0072] Optionally, the determining of the target vegetation species according to the one or more vegetation species includes:

[0073] Determining the vegetation species with the largest quantity in the image data as the target vegetation species;

[0074] Or, determining the ecological environment region corresponding to the construction region, determining the preset vegetation species priority according to the ecological environment region, and determining the target vegetation species from the one or more vegetation species according to the preset vegetation species priority;

[0075] The ecological environment region includes a grassland region, a forest region or a desert region.

[0076] Optionally, since there may be more than one type of target vegetation in each peripheral sub-region, and due to factors such as geographical location, soil environment, and altitude in each peripheral sub-region, different peripheral sub-regions may have different types of vegetation. Therefore, it is necessary to determine the target vegetation type that can best represent the peripheral sub-region. The present invention provides two determination methods. First, when the preset vegetation type prediction model outputs one or more vegetation types, the quantity or coverage area of each type of vegetation in the image data can be directly counted, and the vegetation type with the largest quantity or the largest coverage area is determined as the target vegetation type. This method is simple and direct and is suitable for areas with relatively single vegetation types or obvious quantity differences. The second method is to make a better choice by combining the local ecological environment. First, the ecological environment region to which it belongs can be determined according to factors such as the geographical location, climate conditions, and soil type of the construction area, such as a grassland region, a forest region, or a desert region. Then, according to the characteristics of the ecological environment region, a preset vegetation type priority is set. For example, in a grassland region, grassy vegetation may have a higher priority; in a forest region, tree vegetation may be more important. Then, from the one or more vegetation types output by the preset vegetation type prediction model, a selection is made according to the preset vegetation type priority to determine the target vegetation type. This method is more in line with the principles of ecological environment protection and restoration and can ensure that the target vegetation type is coordinated with the ecological environment of the construction area.

[0077] In summary, the method of the largest quantity determines the target vegetation type by counting the quantity or coverage area, avoiding the error caused by subjective judgment and improving the accuracy; the ecological environment region priority method combines the characteristics of the ecological environment region, ensures that the target vegetation type is coordinated with the ecological environment of the construction area, and further improves the accuracy.

[0078] Optionally, the determining the restoration coefficient corresponding to the peripheral sub-region according to the original vegetation coverage rate includes:

[0079] R = aV 2 + bV + c

[0080] where R is the restoration coefficient, V is the original vegetation coverage rate, and a, b, and c are preset coefficients.

[0081] Optionally, a takes the value of 10, b takes the value of 0.6, c takes the value of 1. When the original vegetation coverage rate V is 5%, the restoration coefficient R is 1.055. When the original vegetation coverage rate V is 10%, the restoration coefficient R is 1.16. When the original vegetation coverage rate V is 20%, the restoration coefficient R is 1.52. The role of the restoration coefficient is to reflect the severity of vegetation restoration in the peripheral sub-region. Generally speaking, the lower the original vegetation coverage rate of the construction area, the relatively lower the corresponding restoration coefficient of its periphery should be. However, the higher the original vegetation coverage rate of the construction area, it means that higher costs are required to carry out ecological restoration on the peripheral sub-region, that is, the corresponding restoration coefficient of the periphery will be higher.

[0082] Since the construction of the power station requires site leveling, earthwork excavation and filling, material stacking, cable trench excavation and other construction activities, these activities will inevitably interfere with the normal growth of vegetation. Especially in the peripheral area outside the power station construction area, the vegetation is usually also severely damaged due to the construction of the power station. Therefore, after the construction of the power station, the vegetation coverage rate of its peripheral sub-region will be much lower than that before the power station construction. Therefore, it is necessary to carry out corresponding ecological restoration on the peripheral sub-region. Based on this, in order to make the restoration coefficient R a positive number greater than 1, c is set to 1.

[0083] Optionally, determining the restoration coefficient corresponding to the peripheral sub-region according to the original vegetation coverage rate includes:

[0084] Determining the planting survival rate of the target vegetation species corresponding to the peripheral sub-region, and determining the restoration coefficient corresponding to the peripheral sub-region according to the original vegetation coverage rate and the planting survival rate of the target vegetation species;

[0085] Determining the restoration coefficient corresponding to the peripheral sub-region includes:

[0086] R = aV 2 + bV + c + d(1 - S)

[0087] Wherein, R is the restoration coefficient, V is the original vegetation coverage rate, a, b, c, and d are preset coefficients, and S is the planting survival rate of the target vegetation species.

[0088] As another alternative embodiment of the present invention, the present invention can also determine the restoration coefficient according to the original vegetation coverage rate and the planting survival rate of the target vegetation species. The reason for considering the planting survival rate of the target vegetation species is that after planting the plants of the target vegetation species, it cannot be ensured that all the vegetation can survive. If some cannot survive, the achievements of the ecological restoration work after the construction of the power station will be greatly reduced. Therefore, after considering the planting survival rate of the target vegetation species, the restoration coefficient will inevitably be further increased. And when the planting survival rate of the target vegetation species is higher, the increase rate of the corresponding restoration coefficient will decrease, but when the planting survival rate of the target vegetation species is lower, the increase rate of the corresponding restoration coefficient will be faster. To meet this specific requirement, the present invention proposes the above formula. The planting survival rate of the target vegetation species represents the proportion of the successfully planted and survived target vegetation species under specific environmental conditions. The higher the planting survival rate, the stronger the adaptability of the target vegetation species in this area, and the higher the success rate of ecological restoration. However, if the planting survival rate is low, an additional increased restoration coefficient may be required to ensure the successful planting and survival of the target vegetation species.

[0089] Optionally, the part of d(1 - S) is the consideration of the planting survival rate S, where d is a preset coefficient representing the influence degree of the planting survival rate on the restoration coefficient. When the planting survival rate S is high, the value of (1 - S) is small, and the influence on the restoration coefficient R is also small; while when the planting survival rate S is low, the value of (1 - S) is large, and the influence on the restoration coefficient R is also greater, thus increasing the restoration coefficient R, which fully reflects the objective manifestation of the planting survival rate in ecological restoration.

[0090] Optionally, after determining each restoration coefficient corresponding to each peripheral sub-region, for each peripheral sub-region, determine the expected vegetation coverage rate corresponding to the peripheral sub-region according to the restoration coefficient corresponding to the peripheral sub-region and the target vegetation coverage rate corresponding to the peripheral sub-region, and traverse all peripheral sub-regions until each expected vegetation coverage rate corresponding to all peripheral sub-regions is determined.

[0091] In step 103, after the construction of the power station is completed, each peripheral sub-region is traversed to obtain its current vegetation coverage rate. For each peripheral sub-region, the current vegetation coverage rate after the completion of the power station construction in it is compared with its corresponding expected vegetation coverage rate. For the peripheral sub-regions where the current vegetation coverage rate is lower than the expected vegetation coverage rate, an indication instruction is generated to indicate the planting of the target vegetation corresponding to the target vegetation species in this area. In the case where the current vegetation coverage rate of any peripheral sub-region is greater than the expected vegetation coverage rate, it is determined that the ecological restoration is completed. However, every preset time interval, the current vegetation coverage rate of each peripheral sub-region still needs to be obtained and adjusted as needed. For the peripheral sub-regions where the indication instruction has been generated multiple times but the vegetation coverage rate still fails to meet the standard, strategies such as expanding the ecological restoration area or merging sub-regions can be considered.

[0092] Optionally, after traversing each peripheral sub-region and obtaining the current vegetation coverage rate corresponding to each peripheral sub-region, the method further includes:

[0093] In the case where the current vegetation coverage rate corresponding to any peripheral sub-region is greater than the expected vegetation coverage rate, it is determined that the ecological restoration of the construction area where the power station is located is completed;

[0094] Every preset time interval, the current vegetation coverage rate corresponding to each peripheral sub-region is obtained. In the case where the current vegetation coverage rate corresponding to any peripheral sub-region is less than the expected vegetation coverage rate, the indication instruction corresponding to this peripheral sub-region is generated again.

[0095] Optionally, after obtaining the current vegetation coverage rate of each peripheral sub-region, these values are compared with the preset expected vegetation coverage rate. If the current vegetation coverage rates of all peripheral sub-regions are greater than the expected vegetation coverage rate, then it can be considered that the ecological restoration of the construction area where the power station is located has been completed, indicating that the ecological restoration measures have achieved the expected effect. To ensure the persistence of the ecological restoration effect, every preset time interval (such as every quarter, every year, etc.), the current vegetation coverage rate of each peripheral sub-region will be obtained again. This is a long-term monitoring process, which helps to detect and solve possible ecological problems in a timely manner. If it is found that the current vegetation coverage rate in any peripheral sub-region is less than the expected vegetation coverage rate, then the indication instruction for this peripheral sub-region will be generated again. These instructions may include measures such as increasing vegetation planting, improving soil conditions, and reducing human interference to restore the vegetation coverage rate of this area. Through long-term monitoring and timely generation of indication instructions, the present invention helps to maintain the ecological balance and sustainable development of the power station construction area.

[0096] Optionally, after traversing each peripheral sub-region and obtaining the current vegetation coverage rate corresponding to each peripheral sub-region, the method further includes:

[0097] For any peripheral sub-region, when the number of times of generating the indication instruction in the peripheral sub-region is greater than a preset number of times, any one of the following steps is executed:

[0098] Expand the ecological restoration area, and remove the peripheral area other than the construction area in the ecological restoration area to obtain an expanded area to be restored, so as to perform ecological restoration on the construction area where the power station is located according to the expanded area to be restored;

[0099] Alternatively, merge the peripheral sub-region into an adjacent peripheral sub-region to obtain a merged sub-region, re-determine the merged vegetation coverage rate corresponding to the merged sub-region, and when the merged vegetation coverage rate is less than the expected vegetation coverage rate corresponding to the adjacent peripheral sub-region, indicate to plant the target vegetation corresponding to the adjacent peripheral sub-region in the adjacent peripheral sub-region until the merged vegetation coverage rate is greater than the expected vegetation coverage rate.

[0100] Optionally, for any peripheral sub-region, if the number of times of generating the indication instruction is greater than the preset number of times, it indicates that the vegetation restoration in this area is difficult or the restoration effect is not ideal, then subsequent countermeasures are triggered. One countermeasure is to expand the ecological restoration area and include the peripheral area outside the construction area into the area to be restored. This can expand the restoration scope, increase the intensity and effect of ecological restoration. The expanded area to be restored will be used as a new restoration target to execute corresponding ecological restoration measures. Expanding the ecological restoration area can increase the restoration scope and cover more areas that need to be restored, thereby enhancing the overall effect of ecological restoration; another countermeasure is to merge the problematic peripheral sub-region with its adjacent peripheral sub-region to form a larger merged sub-region. After merging, it is necessary to re-determine the merged vegetation coverage rate of this area and compare it with the expected vegetation coverage rate of the adjacent peripheral sub-region. If the merged vegetation coverage rate is less than the expected value, indicate to plant the target vegetation in the adjacent peripheral sub-region to increase the overall vegetation coverage rate. Merging the peripheral sub-regions and re-determining the vegetation coverage rate can more scientifically evaluate the restoration effect and adjust the restoration measures according to the actual situation to improve the restoration efficiency. By judging the number of times of generating the indication instruction, the present invention can timely discover the peripheral sub-regions where the vegetation restoration is difficult or the restoration effect is not ideal, and take targeted countermeasures, which helps to improve the pertinence and effectiveness of ecological restoration.

[0101] The present invention aims to minimize the impact of power station construction on the surrounding environment through scientific planning and implementation, and restore or improve the ecological environment quality of the area through ecological restoration means. The division of the area to be restored and the setting of target vegetation species can ensure the pertinence and effectiveness of ecological restoration work. The determination of the restoration coefficient takes into account multiple factors such as the original vegetation coverage rate and the planting survival rate of target vegetation species, and can reflect the actual situation and ecological restoration potential of different peripheral sub-regions. The present invention can comprehensively analyze the characteristics of vegetation coverage rate and vegetation species in the ecological environment before and after power station construction, conduct ecological restoration in a targeted and regional manner, and ultimately achieve vegetation coverage of the environment around the power station, prevent ecological imbalance caused by power station construction. At the same time, the monitoring process continues, and the restoration measures are dynamically adjusted according to the monitoring results to ensure the continuous optimization and improvement of the ecological restoration work.
