对国家重点野外科学观测试验站——祁连山森林生态站排露沟流域土壤水文时空分布特征进行了研究，结果表明：（1）排露沟流域土壤水分年动态具有明显的季节变化，一个水文年分为前蓄墒、失墒、后蓄墒和稳定4个阶段；降水影响生长季节土壤表层水分变化，森林植物影响根系层土壤水分变化，森林植物影响大于降水影响；（2）土壤水分垂直分布随深度而变化，土壤类型问有差异；（3）土壤水分空间分布高海拔多，阴坡次之，阳坡最少。

The paper studied the space-time distribution characteristics of soil water in Pailugou Guili watershed in Qilian Mountains forest ecology monitoring station, a state key field scientific experimental station. The results showed that soil water changed obviously with season and a hydrological year was divided into four phases： early stage of water storing, water losing, late stage of water storing and stable stage of water storing, The precipitation affected the water change in the surface soil layer in growing season while forest vegetation g...
