水土保持规划要求有确定的土壤流失方位及其速率的成图方法。传统的成图法包括实地调查、访问农民等内容,从而获得通用土壤流失方程(U S L E)的六个因子值。U S L E对于土壤侵蚀预报和水土保持规划是一个经验模型。
Soil and water conservation planning requires a defined mapping of soil loss and its velocity. Traditional mapping methods include field surveys, interviewing farmers, etc. to obtain six factor values for the general soil loss equation (U S L E). U S L E is an empirical model for soil erosion prediction and water and soil conservation planning.
