苏南大运河沿线城市热岛现象的卫星遥感分析

SATELLITE REMOTE SENSING OF URBAN HEAT ISLAND EFFECTS FOR SUZHOU,CHANGZHOU AND ZHENJIANG

本文利用陆地卫星ＴＭ热红外波段的数据对苏南大运河沿线城市苏州、常州、镇江的热环境作 了分析，了解各市热岛效应的强度，分布和成因，调查了热岛内部的精细结构。研究表明ＴＭ热红 外图像能较好地揭示城市下垫面的微细热现象的景观结构，反映温度场的分布，可为城市热环境质 量评价和热源调查提供丰富的信息。

The Landsat-5 Thematic Mapper thermal infrared images are processed for the analysis of urban heat island effects (UHIE) in Suzhou, Ohangzhou and Zhenjiang. The intensity, spatial distribution and cause of UHIE are investigated and discussed. It showed that Thematic Mapper data are quite useful for thermal environmental quality appraisal.
