摘要

采用定位观测方法对晋西黄土丘陵沟壑区坡面土壤水分的分布规律进行研究.结果表明

坡向、坡度、坡位是坡面尺度土壤水分分布的重要影响因素.得出了不同立地条件土壤水分的剖面变化与时间动态规律.在此基础上对不同立地条件进行聚类

给出了坡面尺度下不同立地条件的分类结果.通过分类

可以用立地因素代替土壤水分状况

为黄土高原植被建设提供科学的土壤水分依据.

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 ofsoil moisture

and offer a academic base of soil moisture for establishing the system of defendant forestry.
