Abstract
The distribution of soil moisture on slope in loess hilly areas was studied by the method of fixed location observation.Results show that slope degree,slope position and slope direction are the important factors influencing the distribution of soil moisture on slope.We find the laws of profile and seasonal changes of soil moisture on slope.Through the hierarchical cluster of soil moisture of different stands,we may use condition of topography instead of soil moisture,and offer a academic base of soil moisture for establishing the system of defendant forestry.
