Abstract:: The entropy method was first used to compute the ratio of effect factors on soil moisture in this research.We described the impact of the various factors on soil moisture through the weight analysis of them in different soil depths in the Hezhuanggou Basin on the Loess Hilly Region.The results showed that in the fast changed and micro-used depth of soil moisture(0-20cm),the order of weight of the various factors is:slope>slope position>aspect>land use type,the affectation of the aspect and the land use type is almost the same;In the active effective-used depth of soil moisture(20-60cm),it is land use type>slope position>slope>aspect;In the less active depth of soil moisture(60-200cm),it is slope position>slope>land use type>aspect.Based on this,it provided a theoretical basis for the restoration of the ecological construction in the small watershed.
