中文摘要：
利用地貌形态指标对六棱山北麓断层中段的5条冲沟进行定量化研究,流域的冲沟比降指标（SL）、面积高度积分值（HI）和流域盆地形态因子（Bs）的异常值表明5条冲沟的发育对六棱山北麓断层活动性有明显的响应,流域发育处于壮年期。秋林沟口野外实测数据验证并揭示了六棱山北麓断裂晚第四纪以来的活跃性。
英文摘要：
Quantitative study on the geomorphic indices has been carried out on five gullies in the middle of northern front of Liulengshan Mountain.The abnormal values of the indices,including stream length-gradient index（SL index）,hypsometric integral（HI）,and index of drainage basin shape（Bs）,reveal that the evolution of the five gullies has obvious relationship with the neotectonic movement along the northern front of Liulengshan Mountain and the drainage basins are currently in the mature period of geomorphic evolution.The field investigation of the Qiulin gully tests demonstrates the Late Quaternary activities of the fault along the northern front of Liulengshan Mountain.
