通过设计不同裂隙率、不同坡度的石漠化土地,以不同雨强对其进行人工模拟降雨试验,以研究石漠化土地＂五水＂转化过程。结果表明：在石漠化土地的降水过程中,有48.7%~63.5%的水转化为地表径流,5.2%~22.6%的水被土壤吸收,5.3%~33.6%的水被植被截流,有5.6%~9.8%的水形成裂隙水。
通過設計不同裂隙率、不同坡度的石漠化土地,以不同雨彊對其進行人工模擬降雨試驗,以研究石漠化土地＂五水＂轉化過程。結果錶明：在石漠化土地的降水過程中,有48.7%~63.5%的水轉化為地錶徑流,5.2%~22.6%的水被土壤吸收,5.3%~33.6%的水被植被截流,有5.6%~9.8%的水形成裂隙水。

In order to find the process of ＇five water＇ transformation in the rocky desertification land,the artificial simulation rainfall tests were carried out through designing of different rainfall intensities in the different fissure rates and different slopes of rocky desertifieation land. The results showed that,in the precipitation process of rocky desertifieation land,48.7% to 63.5% of the water was transformed into the surface runoff,5.2% to 22.6% of the water was absorbed by the soil, 5.3% to 33.6% of the water was closured by vegetation, 5.6% to 9.8% of the water was transformed into the fissure water.
