蒸发条件下蓄水坑灌法单坑土壤水分运动数值模拟及分析
Analysis and Numerical Simulation of Soil Moisture Evaporation under the Conditions of Water Storage Simple Pit Irrigation
摘要
Abstract
Through combining the lab research with numerical simulation of soil moisture evaporation, the mathematic model of soil moisture movement under the evaporation conditions was established. The alternate implicit scheme method was used to solve the numerical simulation. Based on the test data, the logarithm curve between soil moisture evaporation ratio and external soil moisture(0-5 cm) was set up as the boundary condition of the mathematic model. In general, the computational results from the methods fit the experiment results well.关键词
