摘    要:城市化对气温变化有多大影响是气候变暖研究中最受关注的问题之一。利用永嘉站1971—2011年的地面观测资料,对永嘉县近40年的年平均气温及年平均最高气温、年平均最低气温和5年滑动平均值进行了统计分析。结果表明:近40年来永嘉县年平均气温、年平均最高气温、年平均最低气温均呈上升趋势。城市化加剧了平均最高气温的升高,对平均最低气温的增加影响不明显。

关 键 词:气温变化  城市化  浙江永嘉

Effects of Urbanization on Temperature of Yongjia County in Recent 40 Years
Abstract:To what extent urbanization affects the temperature variations is receiving increasing attention of the researches in climate warming. Changes of annual average temperature , annual average maximum temperature , annual average minimum temperature and 5 years moving average value were analyzed using the ground observation data of the Yongjia station from 1971 to 2011. The results showed that : the annual average temperature , annual average maximum temperature , annual average minimum temperature of Yongjia station showed an upward trend in recent 40 years. Urbanization accentuated the increasing of annual average maximum temperature , and had no obvious influence on annual average minimum temperature.
