摘要:
通过2003~2004年两年的径流小区试验，运用反推法和经验公式确定土壤可蚀性因子（K）的取值，并对两种结果进行比较分析得出衡阳紫色页岩地区的土壤可蚀性因子（K）的取值范围在0.34~0.37之间，为正确认识当地土壤特性从而提出有效减小水土流失危害的对策提供科学依据。
Abstract:
In order to confirm the factor(K) of soil erodibility in purple rock hilly area of southern China,the methods of inversion formula of universal soil loss equation(USLE) and empirical equation were using to get the span of K based on the data gotten from the runoff plot during two years(2003~2004).The result shows that the K value is between 0.34 and 0.37.
