摘要 用流动观察法分别在冬季的白天和夜间测试了西安城区280个点的温度值,对测试数据进行同时性修正后,绘制出城市温度等温线图。分析调查结果后发现:西安冬季的城市热岛中心位于市中心偏东南的区域,在北郊城市主干道、西郊工业集中区也存在副热岛中心。结合远郊温度测量数据,计算出西安城市冬季白天和夜间热岛强度分别为2.5—4.0℃和5.5—6.0℃。 Temperatures data of 280 were gathered locations in Xi' an city in daytime and nighttime in winter on clearness and less cloudy condition by moving auto mobile investigating method, respectively. Then, the isotherms for Xi'an city were presented after correcting data to be synchronous. The results show that centre of urban heat island in Xi' an city locates at southeast of urban centre, and also there are sub-centre of urban heat island nearby central road in north suburb and industrial estate in west suburb. Combining the survey data in exurb, the urban heat island intensity in ordinary winter daytime and nighttime are about 2.5-4.0℃ and 5.5 - 6.0℃ ,respectively.
