摘　　要：在重力侵蚀的各种影响因素中,地形地貌既为重力侵蚀的发生提供基本动力(重力),其形态又是重力侵蚀长期作用的结果。对黄河中游典型区域地形分形和河网沟道分形的计算及其与重力侵蚀相互关系的初步分析表明:通过分形来反映流域地形地貌综合因素是可行的;地形分形与重力侵蚀的关系较为紧密,可以用于重力侵蚀的宏观预测;河网分形与重力侵蚀的关系较弱。Among various affecting factors of gravity erosion,the topography and geomorphy,i.e.the gravity erosion provides the basic dynamic force(gravity force) and its behavior is the results of long-term action of gravity erosion.It shows through the calculation of topographic shaping of typical regions and channel shaping of the river system of the middle Yellow River and preliminary analysis on interrelationship with gravity erosion that it is feasible to reflect the integrated factor of topography and geomorphy of the river basin through shaping;the relation between topographic shaping and gravity erosion is closer,which can be used for macro prediction of gravity erosion and;the relation between river system shaping and gravity erosion is weaker.
