云南日照类型区划的客观分析

OBJECTIVE AN ANALYSIS 0N THE SUNSHINE TYPE DIVISIONS OF YUNNAN

本文根据云南日照百分率年变程曲线类型，应用系统聚类分析中相似系数法，把云南划分为５个日照区。这５个日照区的地域分布及日照类型特点与云南各地天气气候特征及其季节变化有密切的关系。云南的多日照区，月均对应于日照百分率离差系数小值区。表明处于低纬高原的云南，其多日照区，月的太阳能资源可以充分、有效地利用。

In th is paper,there are 5 sunshine divisions for Yunnan divided from the annual variation curve types of the sunshine percentage in Yunnan by using the method ofsimilar coefficient belonged to the systematic clustering analyse method.The regional distribution and the characteris- tics of sunshine types of these 5 divisions are closely related with the characteristics of the weather and climate and with the scasonal variation of Yunnan.
