摘要
实地试验了影响水土流失的主要因子 ,应用通用土壤流失方程预报本地紫色土坡耕地在耕种情况下的水土流失量。经实测资料检验精度良好 ,说明确定的R、K、LS、C。
By testing the primary affection factor of soil erosion.This paper adopts USLE prognostic soil erosion area on sloping farmaland wity purple soil on te condition of ploughtait.The results are excellent examed by the observde information. It explains that method how to count R.K.LS.C.P is perfectly fit for this conditions. The method can be applied to predicting soil erosion on sloping farmland,drawing up soil and water conservation program and transforming or developing poorland.The sloping farmland adopts horizontal ridge tillang with fenders and slope terraced pot tillage and straw covered. These soil conservation tillage methods are simple and easy and effective. And when generalize and do them are easy.
