摘　　要：开发了一个在GIS与遥感支持下基于层次分析法获得区域土壤水资源分布的新方法。本方法首先根据待研究区的特征选取土壤水影响因子,用层次分析法确定因子权重,建立土壤水资源评价模型,以2000年石家庄市为例,选取6个土壤水影响因子,分别是降水、蒸发、海拔、坡度、土壤孔隙度、土地利用方式,最后基于GIS的空间分析功能实现了石家庄市土壤水资源分级。该方法可为快速获取区域土壤水资源分布提供新的途径。This paper developed a new method to research the distribution characteristics of regional soil moisture resources by GIS（Geographic Information System） and RS（Remote Sensing） in accordance with AHP（Analytic Hierarchy Process） and took Shiji- azhuang City in 2000 as a case. Firstly, 6 impact factors which can affect soil moisture content were chosen, namely precipitation, evaporation, altitude, slope, soil porosity and land use, and an evaluation model for the distribution characteristics of soil moisture resources was established by using AHP to ascertain the weights of these factors. Secondly, on the spatial analysis of GIS, the soil moisture of Shijiazhuang City was divided into 5 grades. This can to be a quick method to obtain regional soil moisture.
