若有一种方法,可予测不同土地利用情况下产生的土壤流失量,就可能更好地控制侵蚀。为此,需先测定各种耕作管理方式对于侵蚀程度的影响,选择其中最优的一种,以使土壤流失减少到最低限度。目前,尚无一种适合于澳大利亚国情的方法;但是,一个美国模式“土壤流失通用方程”(USLE),可作为澳大利亚解决这一问题的借鉴。 本文阐述了土壤流失通用方程及其应用范围与限制条件。探讨了澳大利亚在这一方面的前景。
It is possible to control erosion better if there is a way to measure the amount of soil loss that occurs under different land uses. Therefore, we must first determine the impact of various tillage management methods on the degree of erosion, select the best of them, in order to minimize soil erosion. At present, there is no method that is suitable for Australia’s national conditions; however, a US model called the General Equation of Soil Loss (USLE) can be used as a reference for Australia to solve this problem. This paper describes the general equation of soil loss and its application scope and restriction conditions. Explored Australia’s prospects in this area.
