森林坡地二维分布型水文数学模型的研究

A Study on 2-D Distributed Hydrological Numerical Model in the Woody Sloping Field

根据质量、能量守恒定律和森林坡地产汇流特性，并结合土壤结构、地形、地貌条件和降雨情况，建立了描述森林坡地饱和与非饱和带水流运动规律的二维分布型水文数学模型，采用加辽金有限元数值方法求解模型，模拟了研究坡地的下渗和壤中流过程，在此基础上，叶研究坡地产流过程和下渗过程的特点作了较详细的分析。

In this paper, a 2-D distributed hydrology numerical model,which based on the law of conservation of mass and the law of conservation of energy and the specialty of conflux in woody sloping field, was developed to describe the unsaturated-saturated groundwater flow in woody sloping field.The finite element method was uesd to simulate the process of the rainfall infiltration and the flow in soil.With the result,the specialty of flow produce and infiltration was analyzed.
