| 摘 要： | 利用气象台站数据分析北京城郊气温和城市热岛（UHI）强度的年变化及风速对北京UHI的影响;同时分析北京5个城市站点UHI在不同季节的日变化特征。结果表明,近44 a来北京市区与郊区的多年平均气温和UHI强度均呈增加的趋势。风速的降低促进北京城区的UHI出现增加趋势。风速对UHI的季节变化影响也很显著。2005年北京UH...

| Abstract: | The annual variation of intensity of urban heat island(UHI),the impact of wind speed on UHI,and the diurnal variations of five urban sites in different seasons were studied in the paper by using the meteorological data.The result shows that annual average temperature appears an increasing trend in Beijing urban and suburb areas for the past 44 years.The intensity of UHI also shows an increasing trend.There is a negative correlation between the UHI and synchronous wind speed in Beijing region,and the decreas... |
