摘要
分析宁夏1961—2004年的实测资料和计算各站的太阳辐射,结果表明,宁夏太阳辐射和日照时数北部多于南部,且直接辐射多、散射辐射少,太阳能可利用日数多,太阳能装置的利用率较高。利用主成分综合分析,银川的太阳能及其可利用状况在全国排名第3位,固原排名第12位。由此可见,宁夏的太阳能资源丰富,可开发条件优越,综合利用太阳能的潜力巨大。
By analyzing the observation and calculating the solar radiation in Ningxia, we found out that the solar radiation and sunlight in northern Ningxia are more than that in the south, besides, the direct radiation is more and the diffuse solar radiation is less, and the solar available days is more, thus the utilization poten- tial of solar equipment is high. According to results of analyzing on the utilization of solar energy with principal component method, Yinchuan City of Ningxia is ranked at No. 3, Guyuan of Ningxia at No. 12 in cities of China. So the resource of solar energy in Ningxia is rich, and the condition for utilization is good, which are good for developing and using solar energy.
