Study on ecological protection and vegetation restoration model of power transmission and transformation project construction in typical ecologically fragile areas in western China in the new period

This paper explores the ecological protection and vegetation restoration model applicable to typical ecologically fragile areas in western China, and verifies its effect through experimental simulation. First, this paper designs a comprehensive ecological protection and vegetation restoration model, combines different ecological restoration technologies, such as soil and water conservation, vegetation replanting, soil improvement, etc., and proposes a restoration plan that adapts to the natural environment of western China. Then, through the environmental impact assessment model based on remote sensing technology and GIS platform, combined with multiple restoration modes, simulation Xijun is carried out to evaluate the ecological restoration effect under different modes. The simulation results show that the mode of "combining original ecological protection with artificial restoration" has achieved remarkable results in soil stability, vegetation coverage and biodiversity. According to the data analysis, the vegetation cover of the restored area is increased 30%, the soil erosion rate is reduced 18%, and the biodiversity index is increased 15%. By analysing the simulation results, the feasibility and validity of the proposed ecological restoration model is proved.
