- 摘要:
- 本文根据天然降雨径流小区的5年试验资料，研究了地形因素的坡度和坡长与水土流失量的关系，以及降雨因素对其影响。结果表明，坡地水土流失量与坡度和与坡长关系的幂指数变化，均与降雨过程中的30min最大雨强有着密切的关系。经分析得出了反映地形坡度、坡长和降雨因素影响坡地侵蚀的多因素统计模型。
- Abstract:
- The quantitative relationships between topographic factors and loss of soil and water on sloping land and the effects of rainfall factors on the above quantitative relationships were studied in this paper by five years data obtained from field experiment plots under natural rainfall. The results showed that the exponential changes of power-law relationships between loss of soil and water on sloping land and slope steepness and slope length are closely related to the maximum thirty-minute rainfall intensity under single rainfall, the power exponent of slope steepness and slope length of erosion is increases with the maximum thirty-minute rainfall intensity increasing. Then the statistical models of soil erosion reflecting the single rainfall and the mean year are established respectively.
