| 摘 要： | 利用1972－2011年阳泉市3个国家级气象站资料、2011年36个乡镇区域自动站气温资料，分析了阳泉市城市热岛效应的年际变化、季节变化、月变化和日变化特征。结果表明：阳泉市存在弱的城市热岛效应，1972－2011年平均热岛强度0.554 ℃。阳泉市城市热岛强度整体呈显著上升趋势，热岛强度的增加主要是由于夏季热岛强度的增强；热岛强度冬、秋季强，春、夏季弱；12月最强，5月最弱；热岛强度日变化表现为12时最小，从傍晚开始随降温逐渐增大，到早晨气温降到最低时最大，日出之后迅速减小；2008－2011年最强热岛强度出现在2010年1月14日08时，达7.9 ℃。阳泉在升温天气热岛强度变幅增大，易在早晨形成较强城市热岛，下午形成城市冷岛；降温天气热岛强度变幅减小；温度变化较小时则易维持弱的城市热岛。阳泉市主要城市发展因子与霾日数、气温呈显著正相关，在目前的经济发展水平条件下，阳泉市城市化发展可能使城市温度增高，城市绿地面积的增加可能对热岛效应有缓解作用。

| Abstract: | Based on the meteorological data at 3 national weather stations from 1972 to 2011 and air temperature data from 36 automatic weather stations in 2011 in Yangquan, the annual, seasonal, monthly and daily urban heat island （UHI） intensity were analyzed. The results indicate that there is the weak heat island effect in Yangquan and the annual average UHI intensity is 0. 554 ~C during 1972 to 2011. The UHI intensity is in a significant upward trend and its reason is mainly the increase in summer UHI. The UHI intensity is stronger in winter and autumn and weaker in spring and summer, and the maximum and minimum appear in December and May for the monthly vari- ation,respectively. The minimum UHI intensity appears at 12：00 for the daily variation,and the UHI intensity in- creases with decreasing of air temperature from the early evening to early morning, and its maximum appears in the morning when temperature drops to the lowest and decreases rapidly after sunrise. The extreme UHI intensity is 7.9 ℃ at 08：00 on January 14,2010 during 2008 to 2011. In the warming weather,the amplitude of UHI intensity increases in Yangquan and it is easy to form the stronger UHI effect in the morning and the urban cold island effect in the afternoon. In the cooling weather, the amplitude of UHI intensity decreases. It remains the weak UHI effect when temperature changes insignificantly. The major urban development factors in Yangquan are significantly posi- tive correlations with air temperature and the number of hazy days, so urbanization development maybe enable the urban air temperature increase. However, increasing urban green space maybe reduce the UHI effect under the con- dition of the present economic development in Yangquan. |
