利用实验室简易测试方法和指标评价土壤侵蚀度的许多方法,已经有人进行过描述。但迄今为止,在必须描述大量土壤的侵蚀特性时,田间科学工作者却依然面临着一个难题,即:许多简易测试方法由于要求基本分析数据,使样品数量受到限制,或者测试方法的步骤仅仅与土壤对雨滴冲击的反应间接 Many methods of assessing soil erosion using lab-simple test methods and indicators have been described. But to date, scientists in the field still face the challenge of having to describe the erosion properties of large amounts of soils: many simple test methods limit sample size by requiring basic analytical data, or simply Soil response to raindrops is indirect
