| 摘 要： | 根据1981—2010年郑州辐射站太阳辐射和日照资料、洛阳地区9个气象观测站日照资料,采用气候学计算、线性趋势分析等方法和资源丰富程度、利用价值、稳定程度等指标,对洛阳地区太阳能资源进行了计算、分析和评估。结果表明:洛阳地区多年平均总辐射为4842.4MJ·m-2·a-1,总体呈显著减少趋势,减少速率为每年1.4MJ·m-2。夏季辐射丰富,冬季偏少,夏季总辐射量是冬季的2倍;月平均总辐射5月最多(569.7MJ·m-2),12月最少(241.9MJ·m-2);年总辐射孟津最高,为4922.8MJ·m-2·a-1,宜阳最少,为4681.1MJ·m-2·a-1。多年平均日照时数为2064.7h,总体呈显著减少趋势。春季日照时数多,冬季少,春季日照时数比冬季多33.37%;月平均日照时数5月最多(217.3h),2月最少(138.2h);年日照时数孟津最多(2144.9h),宜阳最少(1909.2h)。洛阳各地属太阳能资源丰富区,利用价值较高,各月日照时数6h的天数为9.8~18.1天,全年为162.7~185.3天;太阳能资源也比较稳定,月最大日照时数12月6h的天数为16.9天,是月最小日照时数7月的1.48倍,12月至次年1月不利于太阳能利用。

| Abstract: | Based on the solar radiation and sunshine data from 1981 to 2010 of Zhengzhou radiation station and the solar data of the 9 meteorological observation stations in Luoyang, the solar energy resources in Luoyang area were calculated, analyzed and evaluated using climatological calculation method and linear trend analysis method. The abundance of solar energy resources, its exploitation value and the stability were investigated so as to estimate the solar energy resources. Results showed that: the annual average solar radiation was 4842.4 MJ·m-2·a-1 in Luoyang area, there was a significantly decreasing trend in the solar radiation, and the decreasing rate was 1.4 MJ·m-2 a year. The solar radiation was rich in summer while it was low in winter, the amount of radiation in summer was 2 times of that in winter. The monthly mean radiation was the highest in May (569.7 MJ·m-2) and the least in December(241.9 MJ·m-2). There was difference in the annual solar radiation among areas, with the highest value 4922.8 MJ·m-2·a-1 in Mengjin and the lowest (4681.1 MJ·m-2·a-1) in Yiyang. The annual average sunshine hours was 2064.7 h, which had greatly decreased in the recent 30 years. The sunshine hours in spring was 33.37% higher than in winter. The monthly mean sunshine hours was the highest in May (217.3 h) but the least in February (138.2 h). The solar energy was abundant in Mengjin where the annual sunshine hours were the most (2144.9 h), while that were the least in Yiyang (with the lowest value 1909.2 h). Solar energy in Luoyang area was abundant, and the exploitation value was high. The number of the days of which sunshine hours was longer than 6 h was between 9.8 d and 18.1 d each month, and it was 162.7 d to 185.3 d throughout the year. The solar energy resources were relatively stable, the number of the days when sunshine hours reached 6 h in December was 16.9 d, which was 1.48 times than that in July. The solar energy resource from December to the next January went against its exploitation. |
