摘　　要：利用中南林业科技大学2005～2010年城市森林生态站林内和林窗及长沙市气象站的气温数据,研究了城市森林的温度特征以及城市森林对小气候的调节作用。结果表明:林内、林窗和长沙站的累年月平均气温、最高气温与最低气温的变化趋势基本一致,7月最高,1月最低;城市森林对气温有明显的调节效应,主要表现为对夏季最高气温的降温效应和对冬季最低气温的升温效应,尤其是晴天,林内的平均最高气温比长沙站可低达3.04℃(6月),林内的平均最低气温比长沙站可高达1.26℃(12月)。Air temperature data was recorded in urban forest plantation（UFP）,in gap of urban forest plantation（GUFP） in Changsha city,and in Changsha weather station（CWS）,respectively,from 2005 to 2010.And these data sets were analyzed to clarify the difference in air temperature measured in different site conditions.The results show that：（a） it was almost the same change trend in air temperature in the above three conditions,in terms of average annual temperature and the highest temperature and the lowest temperature;（b） it was higher by 3.04 ℃ in UFP GUFP than in CWS in June with respect to mean highest temperature,whileas it was lower by 1.26 ℃ in December with respect to mean lowest temperature,which was in particular the case in sunny days in summer and winter.These results suggest that urban forest plantation might play an important role in conditioning effect on urban air temperature.
