The soil-water environment in Gobi desert(sandstorm)areas is fragile such that the surface is dry,the vegetation is scarce,and the wind erosion is serious.In the construction of transmission lines in this area,special attention should be paid to the protection of the surrounding surface environment.The soil-water conservation areas for transmission line engineering projects in the Gobi desert(sandstorm)areas are divided into four field regions including tower region,stretching field,overhead field and construction road field so as to design the soil-water conservation approaches respectively,and put forward the feasible engineering measures,plant measures and temporary measures,which is regarded as the reference for the design,engineering and construction of the soil-water conservation approaches for transmission line engineering projects in the same type of areas.
