Impacts of power transmission projects on the surrounding soil environment: prevention and control.


Abstract: The construction and operation of power transmission and transformation projects have certain impacts on water and soil resources within the substation field and the line engineering area, as well as in the surrounding local areas. This paper summarized the impacts of power transmission and transformation projects on soil properties, soil biology, and soil erosion. The engineering activities and associated changes in soil properties would also have an inevitably adverse impact on soil animals. Due to frequent and inadvertent human activities, the risk of invasion by alien species could increase ecological risks, thus affecting the soil biodiversity and the ecological function of the soil. After analyzing and summarizing a 500 kV transmission and transformation project in the coastal area of a subtropical region, this paper proposes prevention and control measures for soil environmental impacts from power transmission and transformation projects.
