遥感影像在城市热岛效应研究中的应用

摘要

利用2009年7月15日获取的Landsat TM卫星影像反演地面温度数据。以青岛半岛地区和胶州北部地区为试验区域，研究城市热岛效应。结果表明，人口聚集区域的温度在30℃左右，山区温度接近25℃，温度与人口分布、地面覆盖物类型密切相关，研究区域的城市热岛效应比较明显。%Landsat TM satellite imagery acquired on 15 July 2009 is used to retrieve the ground temperature data .Qingdao peninsula and the north of Jiaozhou are selected as experimental regions to study urban heat island effect .T he results show that the temperature of populated region is about 30℃ and mountain tem-perature is close to 25℃ .The temperature is related to the population distribution and land cover type . T he urban heat island effect in study area is perceptible .
