摘要: 根据1981—2012年辽宁省3个辐射站太阳总辐射资料和55个国家气象站日照资料,对辽宁省太阳能资源分布进行了评估,并对比分析了美国国家航空航天局(NASA)太阳总辐射数据在辽宁省的适用性。结果表明:辽宁省太阳总辐射平均年曝辐量为4 950 MJ·m-2,空间上呈西北多东部少分布,西北部的建平镇太阳总辐射最强(5 421 MJ·m-2),东部山区辐射量较小,新宾最小(4 506 MJ·m-2)。全省绝大部分地区太阳能资源稳定程度为稳定等级,大部分地区最长连续无日照日数小于6天,空间分布总体规律仍然是西北至东南递增。辽西北地区太阳能资源开发利用优势最大。NASA太阳总辐射数据在辽宁地区明显偏大15%左右,直接应用需慎重。

Abstract: Based on observation data of global solar radiation(GSR) at 3 meteorological stations and sunshine data at 55 meteorological stations during 1981-2014, distribution of solar radiation resources in Liaoning Province is evaluated. Reliability of GSR data from NASA in the same area is also analyzed. The annual mean GSR in Liaoning province is 4 950 MJ/m-2 with decreasing trend from northwest to east area. The maximum value of GSR(5 421 MJ·m-2) is in Jianping town located in the northwest of Liaoning, and the minimum value (4 506 MJ·m-2) is in Xinbin county located in east. The solar energy resources is stable. The number of continuous days without sunshine is less than 6 in most areas of Liaoning Province with increasing trend from northwest to southeast. The northwest region of Liaoning has the highest predominance in solar energy utilizing. Compare to observation data, the annual mean GSR from NASA data is significantly bigger (around 15%), which should be used cautiously.
