摘　　要：为研究福建省的降雨侵蚀力状况,本文基于福建省69个气象站的降水数据,运用R值简易模型、空间分析等方法,揭示福建省的降雨侵蚀力时空格局,结果表明:(1)福建省降雨侵蚀力在空间上分布不均,空间差异较大,R值在105.97~842.79(J·cm·m^(-2)·h^(-1))变化,整体由东南向西北递增;(2)年际变化幅度较大,且逐步增加,平均R值由425.87(J·cm·m^(-2)·h-1)提高到555.91(J·cm·m^(-2)·h^(-1))。Based on the precipitation data of 69 meteorological stations in Fujian Province,it was studied the status of rainfall erosivity in Fujian Province by using the simple R-value model and spatial analysis methods to reveal the spatial-temporal pattern of rainfall erosivity in Fujian Province.The results show as follows:(1)The spatial distribution of rainfall erosivity in Fujian Province was uneven with large difference.The R value varied from 105.97 to 842.79(J·cm·m^(-2)·h^(-1)),increasing from southeast to northwest.(2)the inter-annual change is significant with gradual increase.The average R value was increased from 425.87(J·cm·m^(-2)·h^(-1))to 555.91(J·cm·m^(-2)·h^(-1)).
