摘要
以四川省40个气象站点1971~2000年的逐日雨量资料为基础,采用降雨侵蚀力简易估算方法计算各站点的降雨侵蚀力,分析了四川省降雨侵蚀力的时空分布特征,研究了降雨侵蚀力时空分布规律,研究结果对该地区的水土流失预报和水土保持措施评价具有重要意义。
Based on daily rainfall data in 40 weather stations of Sichuan Province during 1971 to 2000, this study used the simple estimating model of rainfall erosivity to calculate every station's rainfall erosivity at first. And then, the paper analyzed the spatio-temporal distribution characteristics of rainfall erosivity in Sichuan Province, and studied the distribution rules of rainfall spatio-temporal distribution. The study has a great significance for soil and water loss prediction and evaluation of soil and water conservation measures.
