输变电工程水土流失特征分析

Analysis on Characteristics of Soil and Water Loss in Power Transmission and Transformation Projects

选取代表性输变电项目为对象,分析了输变电工程水土流失的特征。结果表明,站区和塔基区平均水土流失量占比分别达46%和22%以上,是造成输变电工程水土流失的主要项目分区。土壤侵蚀模数最大的分区为站区和塔基区,侵蚀级别为强烈,且显著高于其他分区,其随着站区和塔基区占地面积的增大而增大。输变电工程水土流失特征分析可为其水土流失量的计算和水土保持方案的制订提供技术支持。

This paper analyzed the characteristics of water and soil loss of representative power transmission and transformation projects.The results showed that the average water and soil loss in the station area and the tower base area accounted for 46%and 22%respectively,which were the main project areas that cause water and soil loss in the power transmission and transforma-tion project.Areas with the largest soil erosion modulus were the station area and the tower base area.And it is significantly higher than other districts,and the erosion level is strong.The soil erosion modulus increased with the increase of the station area and tower base area.Analyzing the characteristics of water and soil loss can provide theoretical reference for the calculation of water and soil loss and the formulation of soil and water conservation plans in power transmission and transformation projects.
