摘　　要：基于数字高程模型数据(DEM),运用河长坡降指标(SL)、河流Hack剖面、面积高度积分值(HI)及盆地流域形态因子(BS)分析方法对山西省中条山北麓韩阳段6条冲沟地貌发育进行了量化分析。结果表明:中条山北麓韩阳段流域处于地貌演化的壮年期阶段,断层活动性自西南至东北方向呈现先增强后降低的趋势。野外发现盘底村和三新村沟口东岸阶地发育明显而西岸发育相对较弱的一致性规律,说明沟谷东侧山地抬升较强烈、西侧抬升较弱,从而验证韩阳段自西南向东北方向新构造活动性呈现逐渐增强的趋势。Based on DEM data,the quantitative study on the geomorphic indices has been carried out in the Hanyang segment of Zhongtiaoshan Mountains.The indices include stream length-gradient index（SL）,hack profile of river,hypsometric integral（HI）,and index of drainage basin shape（BS）.It is revealed that the Hanyang River Basin is in the mature phase of geomorphic evolution.Moreover,the fault activity presents a trend of increasing firstly and decreasing later from southwest to northeast.The field investigation finds that in both Pandi and Sanxin villages,the eastern terrace developed clearly while the western did not.The phenomenon indicates that the lift of eastern side of the valley is higher than the western side,which further proves the fault activity trend.
