doi:10.7668/hbnxb.2011.S1.060

Abstract

Abstract: In this paper,based on real-time data from automatic soil water observation network in Henan province and observational data of meteorological elements from automatic weather stations,numerical simulation model,one-dimension soil moisture moving in unsaturated soil,is built according the theory of soil hydrodynamics.Soil water contents are analoged for three kinds of main soil type in the topsoil by finite difference method(FDM).The results show the model can simulate the rule of soil moisture moving under the natural conditions.Meanwhile,it becomes the foundation researching the drought-resistant capability of different soil types in Henan province.

Key words: Soil-water movement, One-dimension, Numerical simulation, FDM
