| 摘 要： | 紫色土分布区是我国南方水土流失区的重要组成部分。本文通过对东阳市紫色土坡面土壤侵蚀和降雨因子之间的相关分析,建立了利用降雨量和平均降雨强度对土壤流失量进行预测预报的回归方程,为紫色土地区土壤过度侵蚀的治理提供了定量方法,并为紫色土的综合开发利用提供了科学根据.

| Abstract: | Purple soil areas are important parts of the soil erosion region in southern China. In this paper, the relation between the average intensity of rainfall and the amount of suspended sediment of soil erosion on the natural slopes of purple soil has been systematically analysed. A predicting equation of suspended sediment of purple soil erosion has been set up. Based on this equation, the amount of purple soil erosion could be calculated. It provides a scientific basis for the control of purple soil erosion and the utilization of purple soil resources. |
