| 摘 要： | 基于大同市1960-2007年的地面太阳辐射和日照时数观测资料,采用线性倾向估计、累积滤波器以及M ann-Kendall检验等方法,分析大同市光能资源的变化特征;选择云量并结合近几年的环境监测资料,探讨引起大同市光能资源变化的可能原因。结果表明:大同市年、季太阳辐射呈减少趋势,近几年有增加的趋势,冬季较为明显。年日照时数呈减少趋势,并伴有较大幅度的波动;各季日照时数也呈减少趋势,但春季不显著,冬季日照时数的波动变化导致年日照时数的波动。大同市年、季光能资源的变化主要与空气中污染物浓度有关。采取环保措施改善大气质量是近几年大同市光能资源呈现增加趋势的主要原因。 |

| Abstract: | Based on the observed data of sunshine duration and solar radiation in Datong City,Shanxi Province during the period of 1960-2007,in this paper the change of radiation resources was analyzed by using the trend analysis method,cumulative filter method and Mann-Kendall method.The possible causes resulting in the change of solar radiation were analyzed using the data of cloud cover and the concentrations of main air pollutants.The results show that the annual and seasonal solar radiation was in an obvious decr... |
