摘　　要：本文利用1960—2004年安庆站及周边邻近县站地面气象观测资料,采取统计诊断方法分析了安庆站的气温、低云量、日照、降水日数、风速等气象要素的气候变化特征,并与周边站对应要素值进行对比,分析结果表明:1990年代以后,随着安庆城市规模扩大,安庆站气温、低云量呈上升趋势,日照时数、雨日以及风速呈下降趋势,且有影响加速的倾向特征。Using the surface observed meteorological data of Anqing and its surrounding counties from 1960 to 2004,the climatic variation characteristics of factors such as air temperature,amount of low clouds, sunshine duration,precipitation days and wind speed of Anqing are analyzed by using the statistical method.The corresponding factors of the surrounding counties close to Anging are also compared.The results have shown that because of the development of urbanization since the 1990s,the air temperature, the amount of low clouds of Anqing have been increased,while the sunshine duration,precipitation days and wind speed have been decreased.What is more,it has been an accelerative trend for the influence.
