摘要
在研究陕西黄土区土壤水文特性的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。
This paper first studied the distribution characteristics of soil-hydrological and the facters related to then in the Loess region of Shaanxi province. Then according to the leading index of soil physics clay content, and adsolute moisture in the 100cm soil tier, and measure the difference between the precipitation and evapotranspiration, We divided the whole province loess region into seven broad regions, discussed the agro-hydrological characteristics of soil in each broad region, and put forward the appropriate measures for soil reclamation.
