摘要
用NOAA气象卫星的AVHRR(高级甚高分辨率辐射计)资料和美国陆地卫星TM(专业制图仪)热红外资料对城市热岛作动态监测研究十分有利。本文以北京为例,证明用遥感方法能较细详地分析城市热岛的季节变化,平面展布,以及城市热岛的内部结构和城市热岛与下垫面的关系。文中还对城市热岛的形成和影响因素作了初步分析。这些资料和分析对于科学地进行城市规划、城市环境质量评价和城市环境保护是十分有用的。
It is of great advantage to dynamic monitoring research of urban heat-island to use AVHRR data of NOAA meteor-ological satellite and TM thermal infrared data of Landsat. Some dynamic monitoring for urban heat-island have been carried out in some cities in recent year. Tak-ing Beijing as an example, it is tes-tified that remote sensing ap-proach could be used to analyze in details not only the seasonal and day-night change, plane distribu-tion and inner structure of urban heat-island, but also the influence of factors of groundsurface on forming of urban heat- island. In the future city planning, environmental protection and ur-ban environment quality evaluation process, we must pay more attention to the influence of factors of heat-island.
