摘要:

利用1961 ~ 2010 年长沙市马坡岭站及其周边8 个台站逐月地面气温观测数据和1979 ~ 2010年ECMWF 再分析数据,通过线性回归对气温趋势进行拟合,分析了1961 ~ 2010 年和1979 ~ 2010 年2 个时段气温序列受城市化影响的程度。结果表明: 长沙市夏季的热岛效应比冬季大,城市化对最高气温的影响大,且城市化热岛增暖的绝对影响随时间增强。利用地面观测和再分析2 种不同气温资料,对比分析1979 年以来城市化对长沙市气温影响表明,与再分析背景气候对比得到的热岛效应均比与观测背景气候对比得出的结果小。因此对比分析气温观测资料的差异更能真实的反映长沙市气温受城市化的影响程度,且结果表明城市化对气温增暖贡献显著。

关键词: 气温, 城市化, 热岛效应, 长沙

Abstract:

Based on the monthly surface temperature data at Mapoling station and its surrounding stations of Changsha from 1961 to2010 and reanalysis data by ECMWF from 1979 ~ 2010,the change trend of temperature in Changsha was analyzed by linear regression,and the influence degree of urbanization on temperature was analyzed during the period of 1961 - 2010 and1979 - 2010. The results show that the urban heat island effect in summer was more significant than that in winter,and the influence of urbanization on
maximum temperature was the largest and the absolute influence of urbanization enhanced with time. Comparative analysis about the influence of urbanization on Changsha temperature since 1979 by using the ground observations and reanalysis temperature material was made,which showed that the urban heat island effect compared with reanalysis background climate was smaller than that compared with
observed background climate. So comparative analysis of the difference of observed temperature reflected better to the influence of urbanization on air temperature change in Changsha,and the warming contribution of urbanization on air temperature was significant.

Key words: air temperature, urbanization, heat island effect
