中文摘要：

利用楚雄市2008年实测气温数据和楚雄市气象观测站2008资料,分析了楚雄市2008年城市热岛强度的变化,并与楚雄市往年城市热岛效应做对比分析,得到了2008年楚雄市城市热岛效应的月变化和日变化规律;同时分析了热岛强度与地面风速、相对湿度、气压以及大气污染物的灰色关联度。结果表明,2008年楚雄城市热岛效应的日变化和月变化规律明显,热岛效应呈现出明显的时段性和季节性;气象因子中风速和相对湿度对热岛的影响明显,大气污染物因子中NO2对热岛的影响较大。

英文摘要：

This article uses the measured temperature data and meteorological observatories data of chuxiong city in 2008,analyzing the changes of urban heat island intensity in chuxiong city in 2008,comparing the urban heat island in chuxiong city with previous years,and finding the discipline of chuxiong city urban heat island on changes and hourly in 2008.At the same time,analyzing the gray relational grade among heat island intensity,surface wind speed and relative humidity.The result shows that the discipline of diurnal variation and monthly of chuxiong urban heat island in 2008 changes significantly,showing a marked heat island effect and seasonal periods,and wind speed and relative humidity impacting the urban heat island obviously.
