This paper investigated the situation of head-cuts in Xifeng area, Ning county and Qingcheng county on Dongzhiyuan. We carried out a detailed measurement and analysis of terrain characteristics on the gully heads, and summarized the overall situation of head-cuts on Dongzhiyuan. On this basis we summed up the genetic types of head-cuts that included flow-induced types, sink hole-induced types, fissure-induced types and human-induced types, and analyzed each type.
