土壤侵蚀控制程序,需用制图方法来确定土壤流失的部位和速度.传统的制图方法需要野外勘查和访问农民,来确定构成通用土壤流失方程(USLE)中的六个因子.USLE是土壤侵蚀预报和防治规划的一个经验模型.
Soil erosion control procedures require the use of mapping methods to determine the site and velocity of soil loss.Traditional mapping methods require fieldwork and access to farmers to determine the six elements that make up the common soil loss equation (USLE) .USLE is a soil erosion prediction And an empirical model of control planning.
