| 摘 要： | 在研究陕西黄土区土壤水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，对其土壤的农业水特性值进行了分析评述，并提出相应的改良措施的办法。

| 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. |

| Keywords: | agro-hydrological characteristics difference between the precipitation and evapotranspiration the distribution of soil moisture |
