摘　　要：为了研究输变电工程建设过程中扰动土地面积分布特点,得出水土流失防治重点,为输变电工程水土流失防治工作提供技术支撑,以华北地区29项500 kV输变电工程为研究对象,统计分析变电站防治分区和输电线路防治分区不同地貌类型条件下各防治分区扰动土地面积空间分布特点和成因,并确定水土流失防治重点;通过分析植被恢复、铺设土工布和水泥灌浆桩基础等水土保持实用技术在不同地貌类型条件下防治水土流失和节约水土保持投资方面的实施效果,提出华北地区输变电工程水土流失防护重点部位与措施建议。Based on 29 samples of 500 kV power transmission engineering in North China,geographic distribution characteristics of disturbance area in different geomorphic types are obtained and the causes are analyzed.All these inclusions lead to get the emphasis partitions of power transmission engineerings.Several practical technologies,such as revegetation,geotextile lying and cement grouting transmission tower foundation,are introduced.The application effects of these technologies,which embodied in soil and water loss cutting down and investment reducing,have been verified.Some recommendations were given for soil and water conservation of power transmission engineerings in North China,which could be technical supports on soil and water conservation.
