摘要:
以全省508个雨量站点的长系列逐日降雨资料，利用基于日降雨信息的月降雨侵蚀力模型，估算了浙江省的降雨侵蚀力，分析了其时空分布规律。结果表明：浙江省降雨侵蚀力总体趋势是自北向南递增；降雨侵蚀力年内分配主要集中在4-9月，占年均降雨侵蚀力的77.7%，根据年降雨侵蚀力的季节分配特征，可以将浙江省划分为3个类型区；降雨侵蚀力的年际变化在空间上东南沿海及海岛地区明显高于其他地区。
Abstract:
In order to estimate rainfall erosivity accurately and analyze the spatial distribution and temporal change of rainfall erosivity, a monthly rainfall erosivity model was adopted to calculate the rainfall erosivity in Zhejiang province by using daily rainfall data from 508 stations during 1956-2005. The results show that the spatial distribution of the R value appears increasing trend from north to south. The seasonal distribution of the R value is centralized and the percentage of R value from April to September is 77.7%. According to the seasonal changing character of R value, three regions are classified in Zhejiang province; The CV of R value of year is higher in southeast coastal and island than other region in the spatial distribution.
