本文介绍了室内水平土柱入渗试验和野外垂直入渗试验来测定土壤水分运动参数的方法,并对由黄土的粒度组成来推求土壤水分运动参数的计算方法做了介绍。这些方法对于用数学模型预报农田及流域土壤水分状况,正确地确定土壤水分运动参数有重要参考价值。
This paper introduces the method of indoor horizontal soil column infiltration test and field vertical infiltration test to determine the parameters of soil moisture movement, and introduces the calculation method of deducing the soil water movement parameters from the particle size composition of loess. These methods have important reference value for predicting the soil moisture status of farmland and drainage area with mathematical model and correctly determining the soil moisture movement parameters.
