| 摘 要： | 本文利用解放后的小流域径流资料和八十年代前期的不同治理措施的试验小区径流观测资料, 以及气象部门降水资料, 采用频率统计和数理统计分析方法, 揭示了降雨特征与水土流失量间的内涵关系。结果表明: 小流域的水土流失可用降水指标建立回归方程, 试验小区的水土流失可用主成分方法建立经验计算模式。为进一步研究水土流失规律, 开展小流域综合治理提供了科学依据。

| Abstract: | From the small watershed data since libration and materials in experimental runoff plots under different controlling measures in early 1970's as well as precipitation, the connotative relationship between precipitation and soil and water loss was found by frequency and mathmatical statistics and analysis. The result showed that the soil and water loss in small watershed could be estimated by precipitation regression equation, and in experimental plot by experimential model with main component method, which provided a scientific basis for soil erosion and loss research as well as small watershed comprehensive control. |
