| 摘 要： | 针对苏北花岗片麻岩地区水土流失的自然状况，建立了6种径流小区，进行试验研究。通过对364次降雨径流与土壤流失量的相关分析，得出适合本地区降雨侵蚀力因子R值的简便算式，确定了USLE模型中其他诸因子的取值。运用USLE模型计算的土壤侵蚀量与实测值进行偏差分析，结果表明，准确率达90％以上。该项研究为本地区水土流失预报与监测提供了科学简便的方法，其研究成果为本地区或同类型地区的小流域综合治理及水土保持规划提供了科学的依据。

| Abstract: | Based on the natural conditions of soil and water loss in the granite gneiss region of northern Jiangsu province,6 types of runoff plots were set up for experimental study.By correlation analysis on the runoff and soil loss for 364 times rainfall,a simple and convenient mathematical formula that is suitable to calculate rainfall erosion factor R value for local area was established and other factors of USLE model were also determined.Deviation analysis was conducted between the soil loss calculated by USLE ... |
