摘要
利用南阳市1990-2007年逐年、逐月太阳总辐射与日照百分率资料,采用最小二乘法确定该市的太阳总辐射计算公式,进而推算出广大无辐射观测地区的逐年、逐月太阳总辐射。结果表明,南阳市太阳总辐射历年变化相对较小,全市年总辐射为4 372.17-4 697.17 MJ/m^2,分布趋势为东部和南部多,北部和西部少,其中年总辐射最大值出现在社旗（4 697.17 MJ/m^2）,最低值出现在淅川（4 372.17 MJ/m^2）;在太阳能资源区划中,南阳市属于4级。
With utilizing data about total solar radiation and sunshine percentage of each year and each month of Nanyang City in 1990-2007,the calculation formula of total solar radiation of Nanyang City was confirmed by using least square method,and then the total solar radiations of each year and each month of extensive observed regions without radiation were calculated.The results showed that the change of total solar radiation of Nanyang City over the years was relatively less,the annual total radiation of the whole city was 4 372.17-4 697.17 MJ/m^2,its distribution trend was more in eastern and southern and less in northern and western,the maximum annual total radiation of this City was 4 697.17 MJ/m^2 and appeared in Sheqi and its minimum annual total radiation was 4 372.17 MJ/m^2 and appeared in Xichuan;Nanyang City was classified into class 4th in the zoning of solar energy resources.
