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。
In order to study the distribution characteristics of disturbed land area in the process of power transmission and transformation project, the key points of prevention and control of soil and water loss are obtained, which provide technical support for soil and water loss prevention and control of power transmission and transformation projects. Taking 29 500 kV transmission and transformation projects in North China as the research object, Statistical analysis is made on the characteristics and causes of the spatial distribution of disturbed land area in different prevention and control subareas under different landform types in substation prevention and control substation and transmission line prevention and control and to determine the key points of prevention and control of soil and water loss. By analyzing such issues as vegetation restoration, laying geotextile and cement grouting pile foundation Practical technology in different types of landforms under the conditions of soil and water conservation and conservation of soil and water conservation investment effect of the implementation of the proposed transmission and distribution projects in North China soil erosion prevention key areas and measures proposed.
