Sources, Influencing Factors, and Controlling Measures Configuration of Soil and Water Loss in Power Transmission Line Projects in Different Hilly and Mountainous Regions
[Objective] The characteristics of soil and water loss of different types of power transmission line projects (PTLPs) in hilly and mountainous regions were explored to provide a theoretical reference for the design
monitoring
and prevention of soil and water loss. [Methods] PTLPs in hilly and mountainous regions (low-elevation mountains and hills of Northeastern China
hilly loess region of Northwestern China
hilly region of Southern China
the Qinghai-Tibet Plateau
and the Xinjiang hilly region) in China were taken as the study object. Based on literature review
field investigations and engineering examples
the sources
influencing factors
and controlling measure configurations of soil and water loss in PTLPs of hilly and mountainous regions were studied. [Results] The main sources of soil and water loss in PTLPs could be divided into station area
road area
temporary stacking area
tower area
stretch field area and slag stacking area. The soil and water loss of the PTLPs was spatially variable. The station area accounted for the highest proportion of soil and water loss
which was up to 48%~62% of the total soil and water loss
followed by the tower area. The main source period was the construction period. The influencing factors of soil and water loss and the key points of prevention in the hilly and mountainous regions were significantly different. [Conclusion] There are significant differences in influencing factors and key points of prevention and control of soil and water loss in different hilly areas. Different forms of soil erosion should be considered in the design of soil and water conservation
and the allocation of controlling measures should be adapted to the local conditions.
