摘要
基于1960年～2003年太阳辐射资料，采用Mann-kendall方法、并结合累积距平曲线对太原市年和四季的太阳辐射的突变情况进行了分析。结果表明，太原市年和四季的太阳辐射都存在一次减少突变，但突变点略有不同，年太阳辐射的减少突变主要是与夏季和冬季太阳辐射的减少突变有关，秋季的影响最小。
Using M - K method, the solar radiation data in taiyuan city during 1960 - 2003 is analyzed, the results show that： either the four seasons or annual solar radiation has one abrupt change at least but their points occur in different stages. The contribution of summer and winter solar radiation is more than other seasons and that of autumn is the smallest.
