摘  要：
结合编制输电线路工程水土保持方案实例,对山西省输电线路工程的征占地、水土流失、水土保持分区及主体工程功能分别进行分析与评价。结果表明,山西省500 kV输电线路征占地中,永久占地为塔基占地,临时占地为施工场地、施工道路和弃渣点占地,二者比例约为1∶9;在施工过程中,产生水土流失的主要部位为施工道路,一般会占总流失量的40%~70%,是防治和监测的重点部位;输电线路可以按平原与山丘分为两个一级分区,在此基础上又可分为塔基区、施工场地区、施工道路区和弃渣点区等4个二级分区;通过分析主体工程功能,主体工程对塔基区的工程措施设计比较全面合理,而对临时占地范围内没有进行设计,编制水土保持方案应注重此方面的综合防护。

摘  要：
Land purchase,soil and water loss,division function zones,and main body functions in Shanxi electric transmission line project were analyzed and appraised based on the soil and water conservation plan of electric transmission line project.Analyses indicated that the land purchased for the project was composed of permanent land and temporary land.Permanent land was used for tower footing area and temporary land included construction area,construction roads,and abandoned slag plots.The ratio of permanent land to temporary land was found to be 1∶9.The amount of soil erosion from construction roads was the largest,accounting for 40%~70% of the total amount of soil erosion.Therefore,construction roads were the important prevention and monitoring parts.The area for electric transmission line was divided into the plain area and the mountain and gully area by topographical features.Then they were subdivided into tower footing zone,construction yard zone,construction road zone,and abandonment slag plot zone.According to analysis,the measures in feasibility study report and the system of soil and water conservation were perfect in tower footing zone.However,the system of soil and water conservation was not designed in the temporary zone,and it should be emphasized during comprehensive prevention in the temporary zone.
