Abstract Based on 29 samples of 500kV 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.
