福建省太阳总辐射计算方法及时空分布

根据福州1971—2008年、建瓯1992—2008年、广州1991—2008年、汕头1991—2008年、南昌1991—2008年、赣州1991—2008年共6站历年各月太阳总辐射和日照百分率,采用最小二乘法拟合出各地太阳总辐射的计算公式：Q=Q0（a＋bs）,通过精度对比,确定了福州模式为适用于福建的计算公式,推算出福建各地逐月、季、年太阳总辐射,利用GIS绘制得各季及年太阳总辐射空间分布图,分析福建太阳总辐射时空分布特征,结果表明：福建省太阳总辐射季节及年分布总体趋势是从福建的东南部沿海向西北部减少;季节平均每月太阳总辐射从大到小顺序排列为夏季、春季（秋季）、冬季。

THE CLIMATOLOGICAL CALCULATION AND DISTRIBUTIVE CHARACTER OF GLOBAL SOLAR RADIATION IN FUJIANG PROVINCE

Abstract: In accordance with the monthly global solarradiation and percentage of sunshine from 1971 to 2007 in Fuzhou, 1992 to 2007 in Jianou, 1991 to 2007 in Guangzhou ,Shantou,Nanchan and Ganzhou,experiential coefficients of each month in formula were fitted using least squares methods Q=Q0(a+bs),by precision analyses , regressione quation in Fuzhou is selected to use,and monthly global solar radiations in all parts of the province were calculated. Ananalysis is made of the distribution characteristics in space of solar radiation in four seasons and of total solar radiation,The result sshowed that solar radiation in four seasons and of total solar radiation is decresed from the eastsouth to westnouth in Fujian. solar radiation vary in four seasons ,Summer is the biggest ,Spring and Autumn is secondary and Winter is the smallest .
