中文摘要：

利用保山市及其郊区昌宁1964―2010年47a的气象观测资料,主要选取城区与郊区同期的气温、相对湿度数据进行对比分析,发现保山市城市热岛、干岛强度均逐年增强。热岛强度季节变化春季最强,秋季最弱;日变化T02：00达到最强,而T14：00最弱。干岛季节变化冬季最强,夏季最弱;日变化T02：00最强,而白天较弱。同时,利用灰色模型对保山市城市热岛与干岛强度进行关联度分析,结果表明：对城市热岛、干岛强度影响较大的人文因子均是年末人口,而影响最大的自然因子分别是降水量和总云量。

英文摘要：

By using meteorological data of urban area of Baoshan City and its suburb area（Changning County） during 1964-2010,the urban climatic variation in Baoshan city is analyzed in this paper.A comparison of temperature and relative humidity between the two areas is made,and the results show that：the density of heat island and dry island in Baoshan was increasing year by year.The urban heat island reached the strongest in spring,whereas the weakest in autumn.As for the daily changes,the strongest heat island occurred at night（2 am）and the weakest in the afternoon（2 pm）.However,the density of urban dry island showed an appositive change.The method of Gray Correlation Degree Analysis is applied to analyze the density of urban heat island and dry island in Baoshan city,and the results suggest that：population was the greatest influential humanistic factor of urban heat island and dry island,and the major natural factor affecting urban heat island was precipitation,while that affecting urban dry island was total cloud amount.
