摘要
选取2001～2006年云南省楚雄市气象观测站和楚雄市郊区的南华气象观测站气候资料,以及楚雄市环保局2001～2006年NO2浓度资料,分析楚雄市城市热岛效应的基本特征,然后将楚雄市城市热岛效应月际变化特征与楚雄市大气NO2浓度月际变化特征进行相关性分析。结果表明,楚雄市城市热岛效应有明显的日变化、月际变化和年际变化规律;楚雄市城市热岛效应与大气NO2浓度变化关系呈强正线性相关,相关系数为0.845。
According to the data （2001 ~ 2006）from nianhua observatory in Chuxiong city of Yunnan and the NO2 thickness data （2001 ~ 2006） from Yunnan Chuxiong environmental protection bureau,the characteristics of heat island effect in Chuiong city were analyzed. The correlation analyses of the temperature data from Chuxiong weather station and with the monthly and annually changes of atmospheric NO2 concentration from Environmental Protection Bureau shows that the hot island effect in Chuxiong city has very obvious yearly monthly and daily changing principles. There are strong linear correlation between the hot island effect of Chuxiong and the atmospheric NO2 concentration and the relevance modulus is 0. 845.
