土壤流失动力因素分析及数学模型

The Dynamic Factor Analyses of Soil Losses and the Corresponding Mathematical Model

建立科学的土壤流失方程是世界各国水保学者研究的重点之一。目前现有的国外土壤流失方程大都属于经验公式。本文通过土壤流失及相关因素分析，得出影响土壤流失的几个重要因素，从而建立了土壤流失方程。

Deriving scientific soil loss equations has been one of the most important problems thetexperts in soil and water conservcetion all over the world study.At present,most of the soil loss quations available from abroad are in the form of empirical formulae.This paper analyzes soil losses and related factors.Through this process,we have discovered several important factors which principly affects soil loss,and established soil loss equations.
