| 摘 要： | 为分析林带的排水作用，合理评价与利用水资源，该文应用土壤水动力学原理，建立了林带－农田蒸散条件下的土壤水动力学模型；通过参数的测定与选用，模拟了土壤水分与地下水位的动态变化；并通过算例表明，该模型用来模拟林带－农田中的地下水动态变化是可行的。

| Abstract: | For analysis of the drainage function of forest belt and for rational evaluation andutilization of water resources,based on the principles of soil-water dynamics,a dynamic soil-wa-ter model of forest belt-farmland under evapotranspiration conditions is presented in this paper.Through the measurements and selection of the parameters,the dynamic variations of soil watercontent and underground water level are simulated. The numerical example demonstrates that thepresented medel is feasible for simulation of the variation of underground water contents of farm-land with forest belt. |
