摘要

在研究陕西黄土区土壤水文特性分布特点及其相关因素的基础上，根据土壤的物理粘粒含量，100cm土层的绝对含水量．和年降水蒸发差为主导指标，用模糊数学等价关系聚类，把陕西黄土区划分为7个区．对其土壤的农业水文特性值进行了分析评述，并提出相应的改良措施和办法。

Abstract

After studing on the distribution characteristics of soil agro-hydrology and the factors related to them in the loess region of Shaanxi province

the loess region of whole province is divided into seven sub-regions according to the leading index of soil physical clay content

and absolute moisture in the 100cm soil layer.and the differece between the precipitation and evapotranspiration. Soil agro-hydrological characteristics in each subregion are discussed

and the appropriate measures for soil improvement are put forward.
