以天文参数、纬度和地形作为影响太阳辐射的变量,在GIS支持下建立了福建省太阳天文年辐射的模拟模型,并用地统计工具定量分析了太阳天文年辐射的空间变异方向和空间变异驱动因素。结果表明:福建省太阳天文年辐射主要位于5000~6000 MJ/m2和6000~7000 MJ/m2两个范围内;福建省太阳天文年辐射的变异方向与大地形走向较为一致;结构性因子(天文参数和纬度)对太阳天文年辐射的影响很小,随机性因子(地形中的坡度和坡向等)对太阳天文年辐射的影响相当显著,高辐射主要出现在阳坡。
以天文參數、緯度和地形作為影響太暘輻射的變量,在GIS支持下建立瞭福建省太暘天文年輻射的模擬模型,併用地統計工具定量分析瞭太暘天文年輻射的空間變異方嚮和空間變異驅動因素。結果錶明:福建省太暘天文年輻射主要位于5000~6000 MJ/m2和6000~7000 MJ/m2兩箇範圍內;福建省太暘天文年輻射的變異方嚮與大地形走嚮較為一緻;結構性因子(天文參數和緯度)對太暘天文年輻射的影響很小,隨機性因子(地形中的坡度和坡嚮等)對太暘天文年輻射的影響相噹顯著,高輻射主要齣現在暘坡。

Taking astronomical parameters , latitude and topographic features into considerations , the author established the simulative model of annual extraterrestrial radiation in Fujian province based on the support of GIS , and quantitatively analyzed the direction and driving factors of spatial variability in the annual extraterrestrial radiation by Geostatistics .The results indicated that the annual extraterrestrial radiation in Fujian province varied mainly from 5000 MJ/m2 to 7000 MJ/m2;the spatial variability direc-tion of the annual extraterrestrial radiation in Fujian province was relatively consistent with the lay of the topography ;the structural factors ( astronomical parameters and latitude ) had little impacts on the annual extraterrestrial radiation , while the random factors ( slope and aspect of topography ) had very significant influences on the annual extraterrestrial radiation , and strong radiation mainly appeared on the sunny slope .
