[0002] With the intensification of global warming and ecological degradation, ecological restoration and sustainable management in arid and desertified areas have become global challenges. Traditional photovoltaic power generation projects usually focus on the efficient production of energy, and rarely involve the comprehensive improvement of the ecological environment and the recycling of resources. However, the system design combining photovoltaic power generation and ecological governance, especially in areas with severe desertification, can not only provide clean energy, but also help improve the local climate, increase vegetation cover, and prevent soil erosion. In this context, how to effectively integrate photovoltaic technology and ecological restoration technology, especially collecting precipitation through photovoltaic panels and using these water resources to support vegetation restoration, has become a technical problem that needs to be solved urgently.

[0003] Although existing studies have proposed basic models for collecting water through photovoltaic panels and using it for vegetation irrigation, these models often face several major challenges in practical applications. First, existing systems often fail to maximize the collection and utilization of precipitation, the water collection efficiency is low, and the irrigation system fails to accurately match the water demand and growth cycle of plants. In addition, there is a lack of in-depth research on the planting configuration of vegetation and its interaction with environmental factors (such as wind and sand activity), resulting in sand fixation effects and ecological restoration results that do not meet expectations. Especially in areas with high wind and sand activity, how to design plant configurations and irrigation patterns to optimize vegetation growth and sand fixation functions while ensuring economic benefits is a problem that has not yet been fully solved by existing technologies.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Example 1

[0025] Reference Figure 1 , which is the first embodiment of the present invention, and provides a photovoltaic sand control and characteristic sand industry planning method for efficient utilization of precipitation, including: collecting data of the target area, and designing a precipitation collection and guidance system based on a photovoltaic panel based on the collected data to maximize the collection and utilization of water resources; using the water resources collected by the precipitation collection and guidance system to set irrigation quotas according to the water requirements of sand-fixing plants and Chinese medicinal materials; using the set irrigation quotas and field wind and sand observation data to select and adjust the planting configuration pattern of sand-fixing plants and Chinese medicinal materials; quantitatively analyzing the economic output of different vegetation configuration patterns and the protective effect of vegetation, and implementing the planning scheme of desert photovoltaic field sand control and characteristic sand industry according to the analysis results, and monitoring and evaluating the implementation results.

[0026] The amount of precipitation collected and the water requirement of plants were determined, and a precipitation collecting drip irrigation system was used for fixed-quota irrigation. On this basis, wind tunnel simulation and field wind and sand observations were used to analyze the protective benefits of different sand-fixing plant configuration patterns. Combined with the results of characteristic Chinese medicinal materials and forage yields, and economic benefit estimates, the best synergistic model of protective and economic benefits was screened out and demonstrated.

[0027] According to the annual precipitation collection amount, as well as the equipment layout and terrain of the photovoltaic power plant, a suitable location is determined and a precipitation storage pool is designed. The reservoir is constructed in the principle of small, multiple and evenly distributed to facilitate precipitation collection and irrigation. It is built in the open space outside the photovoltaic panels. The design specification of the water collection pool is 30m3 / 100m photovoltaic panel.

[0028] The integrated research on the planting mode of windbreak and sand-fixing forest belts outside the photovoltaic field uses the wind tunnel double-row one belt, single-row one belt, and uniform three "grass grid sand barrier + Haloxylon ammodendron" configuration modes to analyze the windbreak and sand-fixing benefits of different configuration modes under the conditions of fixed-rate irrigation, combined with field observations at the Jiudun Photovoltaic Park in Wuwei, and screens the best configuration mode. The vegetation growth under the two conditions of collecting precipitation under photovoltaic panels and not collecting precipitation is carried out, and the impact of collecting precipitation on vegetation growth is quantitatively compared and analyzed.

[0029] Research on living sand barrier technology under photovoltaic panels. Plant perennial native herbs such as sand whip and Stipa psammophila in the grid-shaped precipitation infiltration area projected by the gaps between photovoltaic panels. Research and determine the planting pattern with the best sand fixation effect to replace the failed grass grid sand barriers, fix the quicksand, increase the surface resistance to wind erosion under the photovoltaic panels, and solve the problem of erosion at the front of the panels.

[0030] A study on the configuration patterns of characteristic Chinese medicinal materials and forage between photovoltaic panels was conducted. Under fixed-quota irrigation conditions, single rows of Haloxylon ammodendron, Atriplex canescens, Nitraria thorni grafted with Cistanche deserticola and Cynomorium songaricum were planted, and perennials (Glycyrrhiza uralensis, Astragalus membranaceus, Bupleurum chinense, Taraxacum officinale, Apocynum venetum) and forage (Alfalfa) were planted between the rows to form different planting configuration patterns, and the sand-fixing benefits of different patterns were analyzed.

[0044] Configure planting patterns according to strategies, regularly check vegetation growth and wind and sand conditions, track plant growth conditions and environmental changes through real-time data monitoring, and adjust irrigation quotas and plant configurations as needed.

[0045] S4. Quantitatively analyze the economic output of different vegetation configuration patterns and the protective role of vegetation.

[0059] Traditional photovoltaic sand control projects mainly focus on improving power generation efficiency, usually using standard photovoltaic panel designs and simple irrigation systems, lack consideration of the precise matching of precipitation collection and plant water requirements, and do not optimize vegetation configuration to adapt to specific environmental conditions, such as wind and sand activities. Although these methods have shown certain economic returns in terms of power generation, they have obvious limitations in terms of ecological restoration and resource recycling, resulting in insufficient sand fixation effects and soil quality improvements, and have failed to fully tap the potential of combining ecology and economy.
