| 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（盘河农场一云县盆地段）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一晚更新世，晚第四纪活动较弱。

| Abstract: | 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. |
