universal soil loss equation meaning in English

通用土壤流失公式

A quantitative method of rs for monitoring soil losses based on gis and the formula and algorithm of each model factor about the revised universal soil loss equation ( rusle ) are described in this paper , the spatial distribution law of soil erosion is discussed and the amount of soil loss of the small watershed is predicted running the model of rusle by the support of gis
摘要以三峡库区典型小流域为研究区域，通过遥感和野外调查进行信息采集，建立了流域环境数据库；在gis支持下，根据修正通用土壤流失方程( rusle )模型对数据库实施运算操作，探讨了流域内土壤侵蚀强度的空间分布规律，并估算了小流域水土流失量。
