Abstract:

China's desert area is critical for the current and future development of the photovoltaic sector. Combining the construction of photovoltaic power stations with ecological environment repair is an essential prerequisite for the development of the desert-based economy, which must be considered from the basic site selection planning stage. A more comprehensive consideration of environmental factors can help carry out targeted zoning planning for desert areas and implement precise and effective ecological construction work. This paper takes the Badain Jaran Desert and the surrounding desert area as the study area, and adds the environmental constraints affecting the later ecological construction on the basis of the original constraints on photovoltaic power plant siting. It divides the region into four first-level subdivisions according to the suitability for photovoltaic power station construction and further subdivides them into eight sub-zones based on elements such as topography and precipitation. It also puts forward the countermeasures for the ecological construction corresponding to each sub-zone. The ecological construction in areas with less than 50 mm of annual precipitation mainly focuses on the effectiveness of windbreaks and sand fixation, while areas with 50~200 mm of precipitation should have both windbreak and sand fixation as well as ecological restoration effectiveness. In the gobi region, attention should be paid to the protection of the gravel surface, and in the desert region, attention should be paid to the prevention and control of wind and sand hazards.

Key words: solar photovoltaic power station, ecological construction mode, desert ecosystem, adaptive location
