摘  要：
城市化强烈的改变着地表覆被和地表热环境,形成了明显的城市热岛效应。使用3期Landsat TM5第6波段数据和适时气象资料,在Erdas的Modeler模块下建立单窗算法模型反演地表温度,并结合气象年鉴等资料研究近20年来楚雄市城市热岛效应特征。1989年1月,城郊建筑区均温相差0.50℃。1999年12月,城郊建筑区均温相差1.10℃,新城区建筑温度比老城区高0.70℃。2007年3月,城郊建筑均温相差1.35℃,新城建筑区温度比老城区高0.10℃。1989～2007年,楚雄市城市热岛强度逐渐增大,新老城区温度差异逐渐缩小,城郊温度差异逐渐增大,老城区温度逐渐升高;城市高温区由原来的城区普遍高温变为老城区西边部分和工业区两大部分;楚雄市城市高温区受人类活动、地形和工业发展影响比较明显;低温区由原来的城区零星分布变为沿龙川江分布,水体、绿地对城市气温的调节作用明显。

摘  要：
Urbanization changed the land cover and ground hot environment deeply,as a result,the urban heat island effect became more and more obvious. The urban heat island effect of Chuxiong City in recent 20 years was discussed,based on the land surface temperature that retrieved from 3 band 6 data of Landsat TM5 images and real-time meteorological data at the satelite pass and recent year-book using Mono-window algorithm model in the spatial modeler of Erdas Imagine. In January of 1989,the temperature of urban building area was 0.50 ℃ higher than suburb. In December of 1999,the temperature of urban building area was 1.10 ℃ higher than that of suburb and the building area temperature of new town was 0.70 ℃ higher than that of old town. In March of 2007,the temperature of urban area was 1.35 ℃ higher than that of suburb and the temperature of new town was 0.10 ℃ higher than that of old town. From 1989 to 2007,urban heat island intensity become larger,temperature difference of new town and old town reduced but urban area and suburb increased,old city temperature gradually increased. The city high-temperature zone changed from town generally high to the west of old town and industrial area. Urdan high-temperature zone significantly affected by human activities,topography and industry development. Low-temperature zone changed from sporadic urban distribution to along with Longchuan River distribution. The water and green land had great contributions to the adjustment of urban temperature.
