摘　　要：南汀河西支断裂由南西段、中段和北东段组成,被认为是滇西南临沧地区规模最大的活动断裂。南汀河西支断裂北东段(盘河农场—云县盆地段)顺盘河、南桥河展布,延伸至云县盆地。通过分析该段断裂的活动表现、断裂活动环境及地震活动表现,认为南汀河西支断裂北东段最新活动大致在中更新世—晚更新世,晚第四纪活动较弱。The west branch of Nantinghe Fault were divided into three parts： SW-segment, middle segment and NE- segment. The NE-segment extends along Shunpan River and Nanqiao River to Yunxian Basin. According to its active behavior, active environment and seismicity, we think the latest activity of NE-segment fault occurred approximately during middle-late Pleistocene, and the activity in late Quaternary was weak.
