摘要

Jiaocheng fault zone is located in central Shanxi downfaulted system, and controlls the western margin of the Jinzhong Basin. It starts at Nitun Town, Yangqu County in the north and ends to the west of Fenyang City in the south, about 125 km long, striking NE and dipping SE. Based on the survey and research of 41 gullies and 124 knick points along Jiaocheng fault zone, this paper discusses the distribution characteristics of knickpoints of the gullies along Jiaocheng fault zone. Some factors which may influence knickpoint series and knickpoint distance in the investigation of knickpoint are discussed in the end.
