根据1981-2010年郑州气象站的太阳辐射和日照资料以及洛阳气象观测站日照、总云量、低云量、相对湿度、水汽压、能见度资料,采用气候学计算、线性趋势分析、M-K突变检验、相关分析、Min-max标准化等方法,对洛阳地区太阳辐射进行了计算,探讨了太阳辐射的变化特征,并分析了太阳辐射变化的影响因素.结果表明:洛阳1981-2010年太阳总辐射年平均值为4 842.36 MJ/m2,其中1986年最高,为5 245.20 MJ/m2,1989年最低,为4 548.60 MJ/m2.30年总体趋于下降,下降幅度-1.39 MJ/(m2·a).年太阳总辐射在90年代中前期出现突变,1981-1993年平均太阳总辐射为4 812.23MJ/m2,1994-2008年平均太阳总辐射为4 919.55MJ/m2,突变前后年太阳总辐射相差107.32MJ/m2.日照时数和太阳总辐射近30年的变化趋势基本一致.近30年低云量、相对湿度、能见度呈显著下降趋势;总云量总体趋于下降,下降趋势不显著;水汽压总体趋于上升,上升趋势不显著.相关分析表明,总云量、低云量、相对湿度、水汽压与太阳辐射呈负相关,能见度呈正相关.低云量、相对湿度、水汽压、能见度与太阳辐射的相关系数表现为冬季>春秋季>夏季.

Based on the solar radiation and sunshine data from 1981 to 2010 of the radiation station in Zhengzhou and the sunshine duration,cloud cover,relative humidity,vapor pressure and visibility of the meteorological observation stations in Luoyang,variation characteristics and affecting factors of solar radiation in Luoyang were analyzed by means of climatology calculation,linear trend analysis method,Mann Kendall test,correlation analysis and Min-Max stan?dardized method. Results showed that:From 1981 to 2100,the average solar radiation was 4 842.36 MJ/m2 in Luoyang area,the maximum was 5 245.20 MJ/m2 in 1986,and the minimum was 4 548.60 MJ/m2 in 1989. There was a signifi?cantly decreasing trend in the solar radiation in 30 years,and the decreasing rate was 1.39 MJ/m2 a year. There was a turning point of the solar radiation variation in early 1990s. The average solar radiation from 1981 to 1993 was 4 812.23 MJ/m2,and 4 919.55MJ/m2 in 1994-2008. Annual solar radiation difference before and after the variation was 107.32MJ/m2 . The variation trend of the sunshine duration was similar to that of solar radiation. Low cloud cover,rela?tive humidity and visibility had marked drop trends in recent 30 years. There was a downward trend in total cloud cover and vapor pressure had the tendency of increase,but not significant. According to the related analysis,solar radiation was negatively correlated with the cloud cover,low cloud cover and relative humidity,vapor pressure,and positively correlated with visibility. Their correction coefficient was in the order:winter>spring and autumn>summer.
