Theory and strategies for vegetation conservation and ecological restoration in a large-scale photovoltaic power station in the southern Tengger Desert
Promoting the development of new energy and reforming the energy structure are fundamentally cru-cial in addressing climate change and energy scarcity.Vigorously developing photovoltaic new energy is an im-portant approach to achieving the goal of"carbon emission peak and carbon neutralization".In recent years,pho-tovoltaic new energy has experienced a significant surge in growth.However,due to limited land resources un-der the national food security strategy,constructing photovoltaic power stations faces major constraints.To tack-le this challenge,the state encourages the construction of large-scale photovoltaic power station in sandy desert,gravel desert,and desert while strictly ensuring ecological protection.The topography of desert areas is intricate,characterized by harsh wind and sand environments,making the destruction of vegetation a straightforward pro-cess,however,restoring ecological systems in such conditions poses significant challenges.Effectively enhanc-ing the efficiency of photovoltaic power generation while simultaneously safeguarding vegetation presents a for-midable challenge during the construction of large-scale photovoltaic power stations.This study focuses on the in-vestigation and analysis of natural environmental conditions,vegetation status,and soil water characteristics in the project area located at the southern of Tengger Desert.Furthermore,we examine the correlation between sand-fixing shrub cover and shrub mortality as well as the relationship between soil water content and both shrub cover and shrub mortality.Based on the long-term ecological research findings of sand-fixing vegetation,this study proposes scientific recommendations for plant protection and ecological restoration in desert areas,aiming to facilitate the exploration and development of an integrated model combining desert photovoltaic construction with ecological protection and restoration.These proposals aim to provide technical support for establishing high-quality large-scale demonstration base of desert photovoltaic power stations combined with effective desert gover-nance.
