| 摘 要： | 利用安庆市1957-2006年的气温和降水资料，采用线性趋势分析法和统计方法，分析了安庆市近50年的气候变化趋势。研究结果表明：50年来，安庆市平均气温呈上升趋势，其变化倾向率为0．295℃／10a，并以春季增温最显著，对全年气温变化的贡献最大，夏季增温幅度最不明显。年降水量波动性大，夏、冬季降水量上升，春、秋季呈下降趋势，1990年代降水量最多，是多雨期；近7年是降水量最少，是少雨期。

| Abstract: | Using 1957-2006 temperatures and precipitation data of Anqing city,with linear trend analysis and statistical method,climate change trend during recent 50 years in Anqing city is analyzed.The results of the study indicate that:during these years,average temperatures in Anqing city have risen,its change trend rate was 0.295℃/10a and temperature increase was most obvious in spring,summer temperature change was least obvious.Annual precipitation volatility was great,summer and winter rainfalls have risen,spring and autumn rainfalls have declined,the 1990s was pluvial period,and recent seven years have the least rainfall. |
