Effect of Macro-Pores on Soil Saturated Conductivity in Plow Layer

摘要: 介绍了土壤中大孔隙流的研究,并用一种简单的方法对土壤内的大孔隙和中小孔隙的饱和导水率进行分析,同时讨论了农田耕作层大孔隙流和Darcy流饱和导水率的变异情况。

Abstract: This paper discribes the study of preferential flow in soil.A simple method is introduced to the quantitative fractions of the saturated conductivity for soil macro-,meso-and micro-pores.The variations of saturated conductivity of preferential and Darcy flow are also discussed.
