    摘要: 用流動觀察法分別在冬季的白天和夜間測試了西安城區280個點的溫度值,對測試數據進行同時性修正后,繪制出城市溫度等溫線圖。分析調查結果后發現:西安冬季的城市熱島中心位于市中心偏東南的區域,在北郊城市主干道、西郊工業集中區也存在副熱島中心。結合遠郊溫度測量數據,計算出西安城市冬季白天和夜間熱島強度分別為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....
