摘　　要：[目的]动态监测西气东输二线工程中重点地段、重点对象的水土流失状况,为后续长输管线水土保持动态监测提供一定的理论支撑和实践指导。[方法]定位观测与遥感监测方法相结合,在天山山地区,吐哈盆地及河西走廊戈壁沙漠区这3处重点地段进行监测。[结果]工程建设造成了大量新增水土流失,建设过程中新增加的水土流失量为1.61×106 t;在新增加的土壤流失量中,管道作业带流失量占总流失量的93.68%,是施工过程中重点防治区域。[结论]工程建设加剧了项目区水土流失。[Objective]The objective of this study is to monitor the dynamic change of soil and water loss in the key construction sections in the west section of the second line of west-east natural gas transmission pipeline project in order to provide support for the subsequent long-distance transmission pipeline projects.[Methods]Three key sites,which located in Tianshan mountain area,Tulufan-Hamei basin area and Leoss Plateau area in Xinjiang Uygur Autonomous Region,were monitored.Traditional located monitoring,remote sensing and theoretical analysis was adopted.[Results]The large amount（1.61 million tons）of newincreased soil erosion was caused by the construction of the west section of the second west-east natural gas transmission pipeline project.In particular,around 93.68% of soil erosion occurred at the pipeline working zone.[Conclusion]The construction of the west section of the second west-east natural gas transmission pipeline project has intensified soil erosion in the project areas.
