Description

Technical Field

[0001] This application relates to the field of ecological environment restoration and desertification control technology, specifically to a coupled desertification control and ecological restoration system and its construction method. Background Technology

[0002] Currently, my country's "desertification" areas are vast, distributed in an arc shape across the Northwest, North China, and Northeast regions. These areas are rich in solar resources, but also suffer from strong winds, low rainfall, sparse vegetation, and abundant sand sources, resulting in severe wind and sand erosion. This not only damages the surface ecological environment but also hinders regional economic development and energy development. It is estimated that if 1% of my country's desertified area were used for new energy power generation, its installed capacity would exceed the current total installed power generation capacity in my country. Therefore, "desertification" areas have become important sites for photovoltaic power plant construction. However, the construction and operation of photovoltaic power plants in desertification areas face severe sand burial and wind erosion hazards: on the one hand, frequent shifting sand activity and the wind-blocking and sand-fixing effect of the photovoltaic arrays themselves disrupt the original wind and sand flow field, leading to a rise in sand surface elevation, causing photovoltaic modules to be buried, foundation piles to be eroded, and even collapse; on the other hand, the prevailing wind direction in the region and the conventional orientation of the photovoltaic panels create a wind tunnel that exacerbates the transmission of sand into the site, further aggravating the sand damage problem. Currently, the core need for sand prevention and control and ecological restoration is to achieve the coordinated advancement of "windbreak and sand fixation + ecological restoration + resource utilization".

[0003] In existing technologies, ecological restoration technologies that combine photovoltaics with plant cultivation, such as some photovoltaic desertification control projects, adopt the "power generation on the panel, planting under the panel" model, which reduces evaporation by shading the photovoltaic panels and assists plant growth.

[0004] However, current technologies lack specific mechanical sand control measures. In areas with severe wind and sandstorms, photovoltaic panels cannot effectively block near-surface sand, making seedlings susceptible to erosion and resulting in low survival rates. Furthermore, the arrangement of photovoltaic panels does not adequately consider wind protection, leading to a high risk of sand burial. Therefore, current technologies cannot achieve synergistic effects in sand control, power generation, and ecological restoration, resulting in limited sand control effectiveness, long ecological restoration cycles, and low resource utilization efficiency. Consequently, they fail to meet the practical needs of efficient sand control and rapid ecological restoration in desert and Gobi areas. Summary of the Invention

[0005] The purpose of this application is to provide a coupled sand control and ecological restoration system and construction method to solve the above-mentioned problems in the prior art, which can greatly improve the sand control effect, system stability and resource utilization efficiency in desertified areas, and shorten the ecological restoration cycle.

[0006] Firstly, a coupled sand control and ecological restoration system is provided, including: Multiple vertically installed power generation components are arranged along the prevailing wind direction of the area to be repaired, and the light-receiving surface of the power generation components is perpendicular to or forms an acute angle with the prevailing wind direction. Sand-blocking components are laid on the surface of the area to be repaired, and the sand-blocking components have different laying angles at different positions in the area to be repaired. Vegetation is planted on the ground between the power generation components, and in the area below and / or around the sand-blocking components.

[0007] Secondly, a method for constructing the coupled sand-control ecological restoration system described in the first aspect is provided, comprising: Collect environmental data of the area to be repaired; based on the environmental data, determine the placement and orientation of the power generation components; the orientation is perpendicular to the prevailing wind direction of the area to be repaired; Based on the environmental data, the layout location, and the orientation, the laying area of ​​the sand-blocking components and the laying angle in different laying areas are determined. The planting area for vegetation is determined based on the environmental data, the location of the arrangement, the orientation, the laying area, and the laying angle. Based on the arrangement location, orientation, laying area, laying angle, and planting area, a layout diagram of the coupled sand control and ecological restoration system is generated; based on the layout diagram, the coupled sand control and ecological restoration system is constructed.

[0008] Thirdly, an electronic device is provided, which includes a processor, a communication interface, a memory, and a communication bus, wherein the processor, the communication interface, and the memory communicate with each other through the communication bus; Memory, used to store computer programs; When a processor executes a program stored in memory, it implements any of the steps described in the second aspect above.

[0009] Fourthly, a computer-readable storage medium is provided, wherein a computer program is stored therein, and when executed by a processor, the computer program implements the steps of any of the methods described in the second aspect above.

[0010] The coupled sand-control ecological restoration system and construction method provided in this application embodiment include: multiple vertically installed power generation components, which are arranged along the prevailing wind direction of the area to be restored, and the light-receiving surface of the power generation components is perpendicular to or forms an acute angle with the prevailing wind direction; sand-blocking components, which are laid on the ground surface of the area to be restored, and the sand-blocking components have different laying angles at different positions in the area to be restored; and vegetation, which is planted on the ground between the power generation components, as well as in the area below and / or around the sand-blocking components. In this scheme, power generation components serve as the core measure for wind and sand prevention. Utilizing the vertical arrangement of the structural features, a continuous high-altitude windbreak is formed to block high-altitude sandstorms and reduce the overall wind speed in the photovoltaic area. Combined with low-lying sand-blocking components laid at different angles, this specifically reduces near-surface wind speeds and stabilizes surface shifting sand. Appropriate vegetation planting further enhances the survival rate of plants by utilizing the wind-sheltered environment created by the sand-prevention system, rapidly establishing surface vegetation cover. This achieves a synergistic advancement of "wind and sand prevention, energy utilization, and ecological restoration," deeply coupling vertical photovoltaics, multi-angled low-lying sand-blocking components, and vegetation planting. These three elements form a three-layered protective structure of "high-altitude - near-surface - surface," utilizing the synergistic effect of photovoltaic windbreaks and sand-fixing nets to provide a stable environment for plant cultivation, shortening the ecological restoration cycle, and achieving synergistic effects of sand prevention, power generation, and ecological restoration. This can significantly improve the sand prevention effect, system stability, and resource utilization efficiency in desertified areas, while also shortening the ecological restoration cycle.

[0018] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application. Furthermore, the embodiments and features in the embodiments of this application can be combined with each other without conflict.

[0019] Figure 1 This is a side view of a coupled sand-control and ecological restoration system provided in an embodiment of this application. Figure 1 As shown, the system may include: Multiple upright power generation components are arranged along the prevailing wind direction of the area to be repaired, and the light-receiving surface of the power generation components is perpendicular to or at an acute angle to the prevailing wind direction. Sand-blocking components are laid on the surface of the area to be repaired, and the sand-blocking components are laid at different angles at different locations in the area to be repaired. Vegetation, planted on the ground between power generation components, and in the area below and / or around sand-blocking components.

[0020] For example, this restoration system mainly consists of three parts: a vertical photovoltaic sand-control unit, a multi-angle low-profile sand-blocking unit, and a vegetation planting unit. These three parts work together to cover the entire area to be restored, forming a three-dimensional sand-control ecological restoration system. The vertical photovoltaic sand-control unit includes multiple vertically installed power generation components, such as vertical photovoltaic modules, vertical solar thermal modules, or wind-solar hybrid modules. The multi-angle low-profile sand-blocking unit includes sand-blocking components, which are flexible mesh components, plate-like components, or curtain-like components, made of one or more materials selected from polyethylene, polypropylene, biodegradable polymer materials, metal mesh, or composite materials. The vegetation planting unit includes vegetation. Figure 1 As shown, it includes: the area to be repaired indicated by the dashed box, multiple vertically installed power generation components, sand-blocking components laid at various angles, and vegetation.

[0021] Optionally, vertical photovoltaic sand-prevention units are arranged vertically along the prevailing wind direction of the area to be restored or at an acute angle, serving as the first windbreak barrier. For example, the angle between the power generation components and the ground is within the range of 75°-90°. Multi-angle low sand-blocking units are laid between the vertical photovoltaic components and throughout the entire area to be restored, serving as a near-surface windbreak and sand-fixing barrier. Vegetation planting units are distributed between the vertical photovoltaic components, below the low sand-prevention net, and in the surrounding area, serving as the core carrier for ecological restoration. The three form a three-layer protection structure of "high-altitude windbreak - near-surface sand fixation - surface vegetation restoration".

[0022] Optionally, the vertical photovoltaic sand control unit is the core windproof component of the entire system, and its installation method is as follows: 1. Component Selection: Select vertical photovoltaic modules that are resistant to wind and sand, high and low temperatures, and ultraviolet radiation. For example, the module thickness is 3-5mm, the width is 1.0-1.5m, the height is 2.0-3.0m, the photoelectric conversion efficiency is not less than 18%, and the surface is coated with sand and dirt-proof coating to reduce sand and dust adhesion and lower operation and maintenance costs. The module frame is made of galvanized steel to enhance wind and corrosion resistance and adapt to harsh environments such as deserts and Gobi.

[0023] 2. Arrangement method: The photovoltaic modules are arranged vertically along the prevailing wind direction of the area to be repaired, that is, the plane of the photovoltaic modules is perpendicular to the prevailing wind direction to form a continuous windbreak. The vertical photovoltaic modules are arranged in rows and columns, with a row spacing of 4.0-6.0m and a column spacing of 1.5-2.0m. Adjacent modules are seamlessly connected to avoid the formation of wind and sand channels. The bottom of the vertical photovoltaic modules is connected to the ground surface through a fixed base. The fixed base is made of concrete and embedded 0.8-1.2m below the ground surface to ensure stability in strong wind environments. The top of the base is flush with the ground surface to avoid blocking the airflow near the ground surface and to prevent sand accumulation around the base.

[0024] 3. Auxiliary configuration: Vertical photovoltaic modules are connected by wires and equipped with inverters, energy storage devices and transmission lines to store and transmit the electricity generated by the photovoltaic modules, realizing the recycling of solar energy resources; a sand-proof eave with a length of 0.3-0.5m is installed on the top of the module, extending towards the prevailing wind direction to reduce the erosion of the top of the module by wind and sand, and at the same time reduce the amount of sand and dust falling on the surface of the module.

[0025] Optionally, multi-angle low-profile sand-blocking units can be used as auxiliary windbreak and sand-fixing components to reduce near-surface wind speed, fix surface shifting sand, and provide a stable environment for plant cultivation. The installation method is as follows: 1. Selection of sand control netting: High-strength, aging-resistant, and breathable polyethylene sand control netting is selected, with a mesh size of 0.5-1.0cm and a thickness of 0.3-0.5mm. It is laid in multi-angle layers with a tensile strength of not less than 15MPa, which can effectively block sand particles from passing through while ensuring air permeability and avoiding the formation of local eddies that aggravate sand accumulation. The surface of the sand control netting is treated with anti-ultraviolet rays, and its service life is not less than 8 years.

[0026] 2. Laying Angle and Layout: Based on the wind and sand intensity and prevailing wind direction of the area to be repaired, different angles are used for layered laying to form a near-surface three-dimensional sand control system; specifically, it is laid in three areas: 2.1 Windward side of vertical photovoltaic modules: The sand-proof netting is laid at an angle of 30°-45° to the ground surface, with a length consistent with the row spacing of the vertical photovoltaic modules and a width of 2.0-3.0m. It is used to block near-surface sand from the prevailing wind direction and reduce the erosion of the bottom of the vertical photovoltaic modules by sand. 2.2 Area between vertical photovoltaic modules: The sand-proof netting is laid at an angle of 15°-30° to the ground surface, using a grid layout with a grid size of 2.0×2.0m. It is used to reduce the near-surface wind speed in the area between the modules, fix the surface quicksand, and provide a wind-sheltered environment for planting. 2.3 Edge of the area to be repaired (non-windward side): The sand-proof netting is laid at an angle of 5°-15° with the ground surface, with a width of 3.0-5.0m. It is used to block crosswind sand, prevent external sand from entering the area to be repaired, and reduce the loss of quicksand in the area.

[0027] 3. Fixing method: The sand control net is fixed with ground anchors made of steel bars with a diameter of 12-16mm and a length of 0.6-0.8m. The anchors are embedded 0.4-0.6m below the ground surface, and the anchor spacing is 1.0-1.5m. The anchors are evenly distributed at the edges and grid nodes of the sand control net to ensure that the sand control net does not loosen or fall off in strong winds. The sand control nets are connected by overlapping, with an overlap width of not less than 0.2m, to avoid gaps that may form wind and sand channels.

[0028] Optionally, vegetation planting units serve as the core of ecological restoration. Utilizing the wind-sheltered and sand-fixing environment created by vertical photovoltaic modules and low-lying sand-blocking components, suitable native plants are planted to quickly restore surface vegetation cover. The setup method is as follows: 1. Plant variety selection: Following the principle of "suitable trees for suitable sites and priority given to native species", select perennial native shrubs and herbaceous plants that are resistant to wind erosion, sand burial, drought and poor soil conditions. Priority should be given to varieties such as Haloxylon ammodendron, Caragana korshinskii, Hippophae rhamnoides, Artemisia argyi, and Amaranthus chinensis. Shrubs should be 2-3 year old container seedlings, and herbaceous plants should be qualified seeds to ensure plant survival rate and meet the actual needs of harsh environments, making them more practical.

[0029] 2. Planting layout: According to the layout of vertical photovoltaic modules and low sand-blocking components, reasonably plan the planting areas, which are specifically divided into: 2.1 Area between vertical photovoltaic modules: Adopt a shrub-grass composite mode. The spacing between shrubs is 1.5 - 2.0 m, and the row spacing is 2.0 - 3.0 m, configured in a "checkerboard" pattern. Herbaceous seeds are sown between the rows of shrubs, and the seeding rate is 20 - 30 kg / hm²; 2.2 Below and around the low sand-control net: Plant herbaceous plants. Adopt the strip seeding method, with a strip seeding spacing of 0.5 - 1.0 m and a seeding rate of 15 - 25 kg / hm². Utilize the shading and wind-proof effects of the sand-control net to reduce water evaporation and improve the survival rate of herbaceous plants; 2.3 Edge of the area to be restored: Plant shrubs to form a protective belt, with a plant spacing of 1.0 - 1.5 m and a row spacing of 2.0 m, enhancing the overall sand-control ability of the area and guiding the vegetation to spread to the surrounding areas simultaneously.

[0030] 3. Planting and management: Select the planting time in spring (March - April) or autumn (September - October). Before planting, simply level the ground surface and remove large gravel; For shrub planting, adopt the hole planting method, with a hole depth of 30 - 40 cm and a hole diameter of 25 - 35 cm. After planting, water in time to conserve soil moisture; For herbaceous planting, adopt the no-till reseeding method, and gently press after sowing to ensure that the seeds contact the soil; Conduct regular patrols in the later stage, replant and reseed in time, adopt water-saving irrigation measures, supplement water according to the soil moisture condition, and at the same time prevent and control pests and diseases. Prohibit overgrazing to ensure the normal growth of vegetation.

[0031] When sandstorms come, the vertical photovoltaic modules first play a core wind-proof role. The vertically arranged structure of this module blocks the high-altitude sandstorm airflow, reducing the wind speed by 30% - 50%, reducing the impact of sandstorms on the entire area to be restored, and at the same time realizing the utilization of solar energy resources, breaking through the limitation that traditional photovoltaic modules are only used for power generation and have poor wind-proof effects; Subsequently, the low sand-blocking components laid at multiple angles further reduce the near-surface wind speed (the wind speed is reduced by 20% - 40%), block the movement of sand grains, fix the surface flowing sand, and prevent sand grains from being blown up to erode the plant seedlings; In the wind-sheltering and sand-fixing environment formed by the vertical photovoltaic modules and the low sand-blocking components, the plant seedlings are protected from sandstorm erosion. At the same time, the photovoltaic modules block sunlight to reduce surface evaporation, and the low sand-control net reduces water loss, providing suitable conditions for plant growth; As the plants gradually grow, the surface vegetation coverage continuously increases, further enhancing the sand-fixing ability, forming a synergistic cycle of "vertical photovoltaic wind prevention - low sand-control net sand fixation - plant ecological restoration", ultimately realizing the ecological restoration of the area to be restored, and at the same time the vertical photovoltaic modules continuously generate electricity, achieving double benefits of ecology and energy. Among them, the data in this embodiment are only for examples and are not limited thereto.

[0032] Therefore, vertical photovoltaic modules are used as the core for wind and sand prevention. By arranging them vertically and perpendicular to the prevailing wind direction, a high-altitude windbreak barrier is formed. At the same time, low-lying sand-proof nets are laid in layers at different angles (5°-45°) to form a three-dimensional sand prevention structure of "high-altitude-near-ground surface". This not only solves the problem of high-altitude wind and sand impact, but also effectively reduces the near-ground wind speed and fixes the shifting sand. It breaks through the limitations of traditional single sand prevention measures and significantly improves the sand prevention effect.

[0033] The system provided in this application includes: multiple vertically arranged power generation components, which are arranged along the prevailing wind direction of the area to be repaired, and the light-receiving surface of the power generation components is perpendicular to or forms an acute angle with the prevailing wind direction; sand-blocking components, which are laid on the ground surface of the area to be repaired, and the sand-blocking components have different laying angles at different positions in the area to be repaired; and vegetation, which is planted on the ground between the power generation components, and in the area below and / or around the sand-blocking components. In this scheme, power generation components serve as the core measure for wind and sand prevention. Utilizing the vertical arrangement of the structural features, a continuous high-altitude windbreak is formed to block high-altitude sandstorms and reduce the overall wind speed in the photovoltaic area. Combined with low-lying sand-blocking components laid at different angles, this specifically reduces near-surface wind speeds and stabilizes surface shifting sand. Appropriate vegetation planting further enhances the survival rate of plants by utilizing the wind-sheltered environment created by the sand-prevention system, rapidly establishing surface vegetation cover. This achieves a synergistic advancement of "wind and sand prevention, energy utilization, and ecological restoration," deeply coupling vertical photovoltaics, multi-angled low-lying sand-blocking components, and vegetation planting. These three elements form a three-layered protective structure of "high-altitude - near-surface - surface," utilizing the synergistic effect of photovoltaic windbreaks and sand-fixing nets to provide a stable environment for plant cultivation, shortening the ecological restoration cycle, and achieving synergistic effects of sand prevention, power generation, and ecological restoration. This can significantly improve the sand prevention effect, system stability, and resource utilization efficiency in desertified areas, while also shortening the ecological restoration cycle.

[0034] In one example, the power generation components are arranged in a row-column layout, with the distance between adjacent rows greater than the height of the power generation components and the distance between adjacent columns less than the width of the power generation components; the bottom of the power generation components is embedded below the ground surface through a fixed base, and the top of the power generation components is equipped with a sand-proof eave.

[0035] For example, the power generation modules are arranged in rows and columns, with a row spacing of 4.0-6.0m and a column spacing of 1.5-2.0m. Adjacent modules are seamlessly connected to avoid forming wind and sand channels. The bottom of the power generation modules is connected to the ground via a fixed base. The fixed base is made of concrete and embedded 0.8-1.2m below the ground surface to ensure stability in strong winds. The top of the base is flush with the ground surface to avoid obstructing near-surface airflow and to prevent sand accumulation around the base. A sand-proof eave, 0.3-0.5m long, is installed on the top of the power generation modules, extending towards the prevailing wind direction to reduce wind and sand erosion on the top of the modules and to reduce sand and dust settling on the module surface. The data in this embodiment are merely examples and are not intended to be limiting.

[0036] For harsh environments, the power generation components are made of wind-resistant, sand-resistant, and high- and low-temperature-resistant materials, with sand-proof and pollution-proof coatings. The fixing base is embedded deep into the ground surface, and the low-profile sand-blocking components are made of high-strength, aging-resistant materials. The plants are native, drought-resistant varieties, making the system suitable for harsh environments such as deserts and Gobi, ensuring long-term stable operation. The data in this embodiment are for illustrative purposes only and are not intended to be limiting.

[0037] In one example, the sand-blocking components are laid at different angles at different locations in the area to be repaired, including: on the windward side of the prevailing wind direction, the sand-blocking components form a windward angle with the ground surface; in the area between power generation components, the sand-blocking components form an inter-component angle with the ground surface and are arranged in a grid pattern; on the non-windward edge of the area to be repaired, the sand-blocking components form an edge angle with the ground surface; wherein, the windward angle is greater than the inter-component angle, and the inter-component angle is greater than the edge angle.

[0038] For example, taking sand-blocking nets as an example, low-lying sand-blocking nets are laid in layers at different angles to address the characteristics of near-surface wind and sand hazards. Specifically, for the windward side of vertical photovoltaic modules, the sand-blocking net is laid at a windward angle to the ground, for example, at an angle of 30°-45°. Its length is consistent with the row spacing of the vertical photovoltaic modules, and its width is 2.0-3.0m. This is used to block near-surface wind and sand from the prevailing wind direction, reducing wind and sand erosion on the bottom of the vertical photovoltaic modules. For the area between power generation modules, the sand-blocking components are laid at an angle between the modules, for example, at an angle of 15°-30°. A grid layout is used, with a grid size of 2.0×2.0m. This is used to reduce near-surface wind speed in the area between modules, fix surface shifting sand, and provide a sheltered environment for vegetation planting. For the edge of the area to be repaired (non-windward side), the sand-blocking components form an edge angle with the ground surface. For example, the sand-blocking net is laid at an angle of 5°-15° with the ground surface, with a width of 3.0-5.0m, to block crosswind sand, prevent external sand from entering the area to be repaired, and reduce the loss of drifting sand within the area. The windward angle is greater than the angle between components, and the angle between components is greater than the edge angle. The data in this embodiment is only an example and is not intended to be limiting.

[0039] Therefore, based on the differences in wind and sand intensity on the windward side, between components, and at the edge of the area, the laying angle (5°-45°) can be flexibly adjusted to form a near-surface three-dimensional sand control system, which can specifically reduce surface wind speed and fix shifting sand, thus solving the problem of limited effectiveness of single-angle sand control nets.

[0040] In one example, the top of the fixed base is flush with the ground surface; the sand-proof eaves extend towards the prevailing wind direction.

[0041] For example, the top of the fixed base is flush with the ground surface; the sand-proof eaves extend towards the prevailing wind direction. Optionally, the system also includes an environmental monitoring unit, which includes a wind speed sensor, a dust concentration sensor, and a soil moisture sensor, for real-time monitoring of the wind and sand environment and soil conditions in the area to be restored. It also includes an energy storage unit and a remote communication unit. The energy storage unit stores the electrical energy generated by the power generation components, and the remote communication unit transmits system operation data to a remote monitoring platform. An automatic irrigation unit is also included, electrically connected to and powered by the power generation components, for timed or on-demand irrigation of the vegetation.

[0042] In one example, the power generation components are equipped with an inverter, energy storage devices, and transmission lines.

[0043] For example, the power generation components are connected by wires, and an inverter, energy storage equipment and transmission lines are installed to store and transmit the electricity generated by the photovoltaic components, taking into account both ecological restoration and energy utilization, and realizing the recycling of solar energy resources.

[0044] In one embodiment, an embodiment of this application is specifically described.

[0045] Specifically, this embodiment selects the Gobi Desert region in Northwest my country as the area to be restored. The prevailing wind direction in this region is northwesterly, with an average annual wind speed of 3.5-4.5 m / s, annual precipitation of less than 200 mm, annual evaporation of more than 2000 mm, and surface vegetation coverage of less than 5%.

The ground anchor has a diameter of 14 mm, a length of 0.7 m, is embedded 0.5 m below the ground surface, the ground anchor spacing is 1.2 m, and the overlap width of the sand - proof net is 0.25 m.

[0048] 3. Plant planting unit: Haloxylon ammodendron (shrub) and Artemisia desertorum (herb) are selected as planting varieties. For Haloxylon ammodendron, 2 - year - old container seedlings are used, and for Artemisia desertorum, qualified seeds are used; Planting layout: In the area between photovoltaic modules, a shrub - herb compound pattern is adopted. The plant spacing of Haloxylon ammodendron is 1.8 m, the row spacing is 2.5 m, and it is configured in a "pin - shaped" pattern. Artemisia desertorum seeds are sown between the rows of Haloxylon ammodendron, and the seeding rate is 25 kg / hm²; Artemisia desertorum is sown in strips under and around the low - height sand - proof net, with a strip - sowing spacing of 0.8 m and a seeding rate of 20 kg / hm²; Haloxylon ammodendron is planted at the edge of the area to be repaired to form a protection belt, with a plant spacing of 1.2 m and a row spacing of 2.0 m; The planting time is selected in March - April in spring. Before planting, the ground surface is leveled and large gravel is removed. Haloxylon ammodendron is planted in holes (hole depth 35 cm, hole diameter 30 cm). After planting, water is poured to conserve soil moisture. Later, a flexible water cellar is used to store rainwater, and water - saving irrigation and patrol replanting are carried out regularly.

[0049] 4. Implementation effect One year after the implementation of this embodiment, the sand - proof effect, ecological restoration effect and energy utilization effect of this area are detected, and the results are as follows: 4.1 Sand - proof effect: The vertical photovoltaic modules reduce the average high - altitude wind speed in the area by 42%, and the multi - angle low - height sand - proof net reduces the average near - surface wind speed by 35%. The flowing sand movement in the area is effectively controlled, and there are no phenomena of photovoltaic module sand burial and pile foundation wind erosion. The surface sand accumulation is reduced by 78% compared with that before implementation.

[0050] 4.2 Ecological restoration effect: The survival rate of Haloxylon ammodendron reaches more than 85%, the coverage rate of Artemisia desertorum reaches more than 60%, the overall vegetation coverage rate of the area increases from less than 5% to 45%, the stability of the surface soil particles is enhanced, the wind erosion degree is significantly reduced, and a stable surface vegetation community is formed.

[0051] 4.3 Energy utilization effect: The annual power generation of the vertical photovoltaic modules reaches 6.8 million kWh, which can meet the electricity consumption of ecological management and protection equipment in the area and part of the living electricity of surrounding residents, realizing the effective recycling of solar energy resources and taking into account both ecological and economic benefits.

[0052] Two years after implementation, the regional vegetation coverage rate increased to over 65%, forming a virtuous cycle of "photovoltaic windbreak - sand net sand fixation - vegetation sand protection". The ecological environment has been significantly improved. At the same time, the photovoltaic system generates electricity continuously and stably, realizing the coordinated development of sand prevention, ecological restoration and energy development, and verifying the feasibility and effectiveness of this application.

[0053] Traditional ecological restoration methods rely solely on plant planting, resulting in long restoration cycles (typically 5-10 years) and low survival rates. Existing photovoltaic desertification control technologies also require 3-5 years for ecological restoration. This application utilizes the synergistic windbreak and sand-fixing effect of vertical photovoltaic modules and multi-angled low-lying sand-control nets to provide a stable growth environment for plant planting, increasing the plant survival rate to over 85% and shortening the ecological restoration cycle to 2-3 years, significantly improving ecological restoration efficiency. Simultaneously, the vertical photovoltaic modules enable the recycling and utilization of solar energy resources, avoiding waste of land resources and improving the comprehensive utilization efficiency of resources. Compared to existing technologies, this approach has significant efficiency advantages and application value.

[0054] In summary, this application solves the technical problems of poor sand control effect, long ecological restoration cycle, low resource utilization efficiency and poor system adaptability in existing sand control and ecological restoration technologies. It constructs an efficient, stable and sustainable vertical photovoltaic coupled mechanical measures sand control system ecological restoration method, which has significant innovation and practicality and can be widely applied to ecological restoration and energy development in deserts, Gobi and other areas severely affected by wind and sand.

[0055] Figure 2 This is a flowchart illustrating a method for constructing a coupled sand-control ecological restoration system, as provided in an embodiment of this application. Figure 2 As shown, the method may include: Step S101: Collect environmental data of the area to be repaired; based on the environmental data, determine the placement and orientation of the power generation components; the orientation is perpendicular to the prevailing wind direction of the area to be repaired.

[0056] In one example, environmental data includes one or more of the following: light data, wind data, terrain data, soil data, and vegetation data.

[0057] For example, environmental data of the area to be repaired is collected. Based on the environmental data, the placement and orientation of the power generation components are determined. Specifically, the light-receiving surface of the power generation components is perpendicular to or at an acute angle to the prevailing wind direction. The power generation components are vertical photovoltaic modules, vertical solar thermal modules, or wind-solar hybrid modules, etc. Taking vertical photovoltaic modules as an example, the orientation of the vertical photovoltaic modules is arranged to be perpendicular to or at an acute angle to the prevailing wind direction.

[0058] Optionally, environmental data may include one or more of the following: light data, wind data, topographic data, soil data, and vegetation data. Specifically: Sunlight data, including solar radiation intensity, sunshine duration, and solar altitude angle; Wind data, including prevailing wind direction, average wind speed, maximum wind speed, and wind frequency distribution; Topographic data, including surface elevation, slope, aspect, and dune distribution; Soil data, including soil type, soil moisture content, and soil nutrient content; Vegetation data, including existing vegetation coverage and vegetation types.

[0059] Step S102: Based on environmental data, layout location and orientation, determine the laying area of ​​the sand-blocking components and the laying angle in different laying areas.

[0060] For example, the sand-blocking components are flexible mesh components, plate-like components, or curtain-like components. Based on environmental data, placement location, and orientation, the laying area of ​​the sand-blocking components and the laying angle in different laying areas are comprehensively determined. Taking sand-control netting as an example, the laying angle of low-profile sand-control netting in different areas is generated as a multi-level angle that varies with location.

[0061] Step S103: Determine the planting area of ​​vegetation based on environmental data, layout location, orientation, laying area and laying angle.

[0062] For example, the planting area, vegetation type and variety are determined comprehensively based on environmental data, layout location, orientation, laying area and laying angle.

[0063] Step S104: Generate a layout diagram of the coupled sand control and ecological restoration system based on the layout location, orientation, laying area, laying angle and planting area; construct the coupled sand control and ecological restoration system based on the layout diagram.

[0064] In one example, the terrain data includes surface elevation, slope, aspect, dune type, and dune movement direction. When generating the layout map of the coupled sand control and ecological restoration system, at least one of the following layout rules is executed based on the terrain data: If the area to be restored contains dunes, the power generation components are placed on the upper part of the windward slope of the dunes or along the dune ridge, and the light-receiving surface of the power generation components is perpendicular to the prevailing wind direction; if the slope of the area to be restored is greater than a preset slope threshold, the power generation components are arranged in a stepped manner along the contour lines; if the area to be restored is flat sand, the power generation components are arranged in a uniform row and column layout, and the row spacing decreases as the prevailing wind speed increases; if the area to be restored contains depressions, the sand-blocking components are laid on the upwind side of the depression edge, and the laying angle is greater than the laying angle of the area between the components.

[0065] For example, a layout diagram of a coupled sand control and ecological restoration system is automatically generated based on the placement location, orientation, laying area, laying angle, and planting area; the coupled sand control and ecological restoration system is then constructed based on the layout diagram. Furthermore, historical layout diagrams can be obtained, and the currently generated layout diagram can be compared with historical layout diagrams to generate improvement information. This improvement information can then be used to specifically adjust the coupled sand control and ecological restoration system, resulting in the final coupled sand control and ecological restoration system.

[0066] Optionally, the layout optimization algorithm can be a multi-objective optimization algorithm, such as a genetic algorithm, particle swarm optimization, simulated annealing, neural network model, or rule-based knowledge base system, without limitation. When generating the layout map according to the layout optimization algorithm, at least one of the following is taken as the optimization objective: maximizing wind protection efficiency, maximizing power generation, maximizing plant survival rate, minimizing system cost, and maximizing overall benefits. The algorithm output is a Pareto optimal solution set, and the layout scheme with the highest comprehensive score is selected as the final layout map.

[0067] Optionally, the terrain data includes surface elevation, slope, aspect, dune type, and dune movement direction. When generating the layout map of the coupled sand control and ecological restoration system, at least one of the following layout rules is executed based on the terrain data: If the area to be restored contains dunes, the power generation components are placed on the upper part of the windward slope of the dunes or along the dune ridge, and the light-receiving surface of the power generation components is perpendicular to the prevailing wind direction. If the slope of the area to be restored is greater than a preset slope threshold, the power generation components are arranged in a stepped manner along the contour lines. If the area to be restored is flat sand, the power generation components are arranged in a uniform row and column layout, and the row spacing decreases as the prevailing wind speed increases. If the area to be restored contains depressions, the sand-blocking components are laid on the upwind side of the depression edge, and the laying angle is greater than the laying angle between the components.

[0068] When the power generation components are placed on the windward slope or ridge of a sand dune, the mounting base can be a helical pile foundation or an extended anchor base, with an embedding depth greater than that for flat terrain, and an enlarged end or anchor plate at the bottom of the base. When the sand dune movement speed exceeds a preset threshold, a detachable base or sliding rail installation structure is used to facilitate periodic adjustment of the component position to adapt to dune movement. For example, for sand dunes with relatively fast movement (e.g., annual movement >5m), a detachable base is used, and the components are moved to a new location every 1-2 years. Alternatively, a sliding rail installation can be used, allowing the components to slide within a certain range to adapt to changes in dune morphology.

[0069] When power generation components are placed on the upper-middle part of the windward slope of a sand dune or along the dune ridge, the process also includes foundation pretreatment of the installation area and the installation of local sand-proof netting around the base to prevent wind erosion. Specifically, foundation pretreatment includes: injecting cement grout or chemical grout into the sand around the base to complete grouting reinforcement and improve the cohesion and bearing capacity of the sand; manually or mechanically compacting the installation area to achieve layered compaction and improve the density of the sand; and laying geogrids around the base to form a composite foundation with the sand to distribute the load.

[0070] Furthermore, localized sand-proof netting or gravel coverings are installed around the fixed base of the power generation components to prevent wind erosion of the surrounding sand. For example, within 0.5-1.0m on the windward side of the base, a high-angle sand-proof netting (at 45°-60° to the ground surface) or a layer of gravel is laid to reduce localized wind erosion. Regular inspections are conducted, and sand is backfilled promptly upon detection of wind erosion. Lateral connecting members can be installed between adjacent power generation components to form an integrated frame structure. Multiple power generation components in the same row are connected by lateral connecting rods at the top or middle, allowing multiple components to share the load, improving overall overturning resistance and enhancing wind resistance stability.

[0071] Optionally, the sunlight and wind data are time-series data. When generating the layout diagram of the coupled sand control and ecological restoration system, the complementary characteristics of the sunlight and wind data in time are first determined. Based on the complementary characteristics and the layout optimization algorithm, the type combination and arrangement of the power generation components in the coupled sand control and ecological restoration system are generated.

[0072] Specifically, if the complementary characteristics are determined to include an average daytime irradiance greater than a first preset irradiance threshold and an average daytime wind speed less than a first preset wind speed threshold, and an average nighttime wind speed greater than a second preset wind speed threshold, then a layout diagram of the wind-solar hybrid components is generated. The wind-solar hybrid components include vertical photovoltaic modules and vertical axis wind turbines. The vertical axis wind turbines are concentrated on the upwind edge of the area to be repaired, and the vertical photovoltaic modules are arranged on the downwind side of the wind turbines.

[0073] If the complementary characteristics are determined to be seasonal complementarity between annual sunshine and wind, a layout diagram of a hybrid photovoltaic (PV) and wind power array is generated; the proportion of PV modules in the layout diagram is greater than the proportion of wind turbines. If the complementary characteristics include an annual average wind speed greater than a third preset wind power threshold and an annual average sunshine intensity less than a second preset sunshine threshold, a layout diagram with wind power as the primary source and PV as a secondary source is generated; the layout diagram includes vertical PV modules and wind turbines, with the vertical PV modules arranged on the downwind side of the wind turbines. If the complementary characteristics include an annual average sunshine duration greater than a preset sunshine duration threshold and an annual average wind speed less than a preset wind power threshold, a pure vertical PV layout diagram is generated.

[0074] The method provided in this application involves collecting environmental data of the area to be restored; determining the placement location and orientation of the power generation components based on the environmental data; the orientation being perpendicular to the prevailing wind direction of the area to be restored. Based on the environmental data, placement location, and orientation, the method determines the laying area of ​​the sand-blocking components and the laying angle in different laying areas. Based on the environmental data, placement location, orientation, laying area, and laying angle, the method determines the planting area for vegetation. Based on the placement location, orientation, laying area, laying angle, and planting area, a layout diagram of the coupled sand-blocking ecological restoration system is generated; based on the layout diagram, the coupled sand-blocking ecological restoration system is constructed. Therefore, this application innovatively integrates power generation components, sand-blocking components, and vegetation. The power generation components provide both wind protection and power generation, while the multi-angled, low-profile sand-blocking components provide a sheltered environment for planting and sand fixation. Vegetation further enhances sand fixation capacity and improves the ecological environment. At the same time, vegetation cover can reduce sand and dust adhering to the surface of photovoltaic components, improve power generation efficiency, and form a synergistic cycle of "wind protection-sand fixation-power generation-ecological restoration". The three components form a three-layer protective structure of "high altitude-near ground surface-ground surface". By utilizing the synergistic effect of photovoltaic wind protection and sand net sand fixation, a stable environment is provided for planting, the ecological restoration cycle is shortened, and the synergistic effect of sand prevention, power generation, and ecological restoration is achieved. This can greatly improve the sand prevention effect, system stability, and resource utilization efficiency in desertified areas, and shorten the ecological restoration cycle.
