| 摘 要： | 利用2007年夏季常规和自动站气象观测资料,分析研究苏州城市热岛及其与影响因子关系.气温分布表明,市中心干将桥气温相对较高,而靠近太湖的新区镇湖镇、东山等郊区气温相对较低.苏州城市热岛强度日变化呈现双峰分布,两个峰值分别出现在10时和20时左右,最低值出现在16时左右.热岛强度与气象条件关系分析表明:(1)热岛强度受云量的影响较大;(2)与城区气温分布关系密切,相关系数为0.62;(3)与风向有关,城区风向为西风时的热岛强度大于东风时热岛强度;而城区热岛强度与风速关系不明显.另外相关站点的合理选取对城市热岛研究也十分重要.

| Abstract: | Based on the data of 10 weather stations in summer of 2007 in Suzhou,the urban heat island effect and its characteristics are analyzed,the relationship among meteorological factors are also analyzed.The temperature of the ancient city area of Suzhou is obviously higher.However,the temperature of the rural area near Taihu Lake is lower.The diurnal change of urban heat island intensity indicates that there are two peaks,and the minimum of the UHI intensity appears at 4:00pm.By analyzing the urban heat island ... |
