摘    要:根据苏北花岗片麻岩区水土流失状况,布设6种处理的径流小区进行了9年试验观测,通过对364次降雨径流与泥沙流失量的相关分析,得出了适合本地区R值的简便算式和USLE中各因子的取值。采用USLE计算的土壤流失量与实测值比较,准确率达90%以上。本研究成果为该类地区水土流失预报与监测提供了科学简便的方法。

关 键 词:USLE  江苏北部  花岗片麻岩区  适用性

Abstract:According to soil and water loss conditions of granite gneiss region in the northern Jiangsu, we have set 6 types of runoff plots and tested and observed for 9 years. We have obtained a simple and convenient mathematical formula which is suited to R value of the local area and suited to the adopted value in USLE of all factors of climate characteristic and soil conditions of the local area through correlative analysis of 364 events of rainfall runoff and soil lost. Comparing soil lost and observed value calculated by USLE, the accuracy rate is greater than 90%. The studied results have provided a scientific and simple method for forecasting and monitoring soil and water loss of the same type regions.
Keywords:USLE  northern Jiangsu  granite gneiss region  applicability
