| 摘 要： | 为探索西北部中等城市的城市热岛效应规律,利用2004—2010年天水市城、郊自动气象站资料,对天水市城、郊温度差异进行了系统分析。结果表明:天水市城区热岛效应比较显著;冬季是热岛现象最强的季节,夏季是热岛现象最弱的季节;城区热岛现象持续时间为18:00—10:00,占全天的2/3,最大强度达1.5℃;城区凉岛持续时间为11:00—17:00,占全天的1/3,最大强度为0.3℃;地面温度城、郊差比气温更大,40cm以下城区地温全年大于郊区;降雪日及连阴雨天气的中后期,城区基本上维持凉岛;强降温天气下,城、郊气温变化基本一致,差别不大。

| Abstract: | To explore the urban heat island(UHI) at medium-sized cities in the Northwest,the difference of temperature in the urban area and suburbs was analyzed with the meteorological data in automatic meteorological stations in Tianshui city from 2004 to 2010.The result showed that the heat island was obvious in urban area of Tianshui,with the strongest heat island appearing in winter and the weakest in summer.The urban area played as aheat islandduring 18:00 to 10:00 which was two-thirds of the day with the bigges... |
