【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)。更多还原

【Abstract】 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).更多还原
