摘要
通用土壤流失方程式是世界上应用最广泛的估测土壤侵蚀量的公式,在我国建设项目水土流失的环境影响评价中也有重要的应用价值。本文根据方程式各因子的物理意义和工程施工的特点,具体说明了各因子在环境评价中的取值方法及方程式的应用范围。
The Universal Soil Loss Equation (USLE) is the most widely used model to estimate water erotion amount, and can be adapted in the Environmental impact Assess ment (EIA) to predict soil erotion qantitively in China. The present paper is mainly focused on methods for determining and modifying each USLE factor when the USLE is applied in the EIA research.
