摘要: 以湖北省的21个测站和周边省市的14个辅助测站多年的逐月降雨量数据为基础,利用Arnoldus提出的简便算法计算多年年均降雨侵蚀力(R值),并在Arcview软件的支持下分析了其降雨侵蚀力时空分布规律。结果表明:湖北省多年年均降雨侵蚀力总体趋势是由北向南递增;降雨侵蚀力的月分布情况与降水量的月分布情况基本一致,月R值的年内动态变化显著;年R值的年际变化在空间分布上大致呈东北部高、西南部低的特点。

Abstract: On the basis of continuous monthly rainfall data of 21 stations in Hubei Province and 14 stations in circumference provinces, the rainfall erosivity R value is calculated by using Arnoldus simple method, and a spatialtemporal distribution analysis supported by Arcview software. The results show as follows: The spatial distribution of the R value appears increasing trend from north to south. The monthly spatial distribution of the R value is very similar to the distribution of rainfall, and the R value dynamically changes evidently among several months. The three indexes of the R value in year are characteristized by higher values in northeast region of Hubei Province and lower in southeast.
