| 摘 要： | 土壤水分状况是形成泥石流的关键性水文因素之一，了解土壤水分的变化状况，对于泥石流的形成机理以及预报预测研究都有重要的科学意义。以云南东川蒋家沟为研究对象，基于水分的物理循环过程并与分布式水文分布模型TOPMODEL相结合，建立起土壤湿度逐日变化模拟模型。从蒋家沟流域2001年的模拟结果来看，基本上能够反映出观测点的表层土壤湿度的取值范围及其基本变化趋势，所构造的模型能够比较好地模拟出流域内土壤湿度逐日变化情况。

| Abstract: | Soil moisture is one of the key hydro factors which caused the debris flow.To know the variation of the soil moisture is very important to the research of the initiation and the prediction of the debris flow.In this paper,a simulation model,based on the physical process of hydro cycle and the distributed hydrology model:TOPMODEL,is built to simulate the soil moisture variation in Jiangjia ravine of Yunnang in 2001.The simulation result is validated with the field surveying data which is got from 20 June to ... |
