| 摘 要： | 近年来,城市热岛效应已成为一个日益突出的城市环境问题,并受到了普遍关注。本文主要利用泉州市1989年、1996年Landsat TM以及2003年Terra ASTER遥感卫星影像来反演地表温度、地表反照率和植被指数等重要参数,然后结合当地的气象数据来进一步反演泉州市区的显热和潜热通量,分析了它们这些年发生的变化。研究表明泉州市区显热通量的高值分布区与城市建成区的分布范围基本吻合,并且在这些年中的分布面积不断增加。

| Abstract: | Recently,the urban heat island has become one of the most serious city environmental problems and has been intensively focused on.To study the urban heat fluxes,two Landsat TM images and one Terra ASTER image of Quanzhou city,China were first used to extract the land surface temperature,albedo and vegetation index for the years of 1989,1996 and 2003 respectively.Then,by combing with local meteorological data,the sensible and latent heat fluxes were retrieved.Furthermore,the changes of the urban heat fluxes during the study period were also detected.The study revealed that the distribution of high value of sensible heat flux was consistent with the urban built-up land areas,while the urban heat fluxes has been increased. |
