摘要

该文基于野外观测资料，分析探讨了天然降雨因素及地面坡度对片状侵蚀的影响。研究结果表明：反映降雨特性的指标E1-

和综合反映降雨和地形因子的指标径流势能Ep是影响片蚀显著的主要特征因子。通过分析，提出了具有物理概念的片蚀模型，这为进一步研究并建立坡面土壤侵蚀整体预报模型提供了片蚀建模的分析依据。

Abstract

This paper ishsed on the field observed data to study the effects of natural rainfall factors and slope steepnesson sheet erosion. The results show that the index of EI_(30) (prduct of kinetic energy and maximum thirty-minuteintensity of rainfall)which reflected the characteristics of rainfall and the potential energy of runoff which is a com-prehensive index of including rainfall factors and topographical factors are important factors on affecting the sheeterosion. The sheet erosion models with clear physical conceptions are presented by analysing

and these can be pro-vided analytical basis for establishing prediction models of soil erosion on sloping land.
