| 摘 要： | 热岛效应是城市化对城市环境影响的一个重要特征.为了研究自贡市10年来城市化进程对热岛效应的影响,采用TM数据与GIS相结合的方法定量分析城市地表温度的时空变化.根据2000和2009年两个时相的LandsatTM影像本文提取了研究区的地表温度以及土地覆被信息,在此基础上对这10年来自贡地区的热岛时空变化及其与植被、建筑用地变化的关系进行研究.分析结果表明,研究区地表温度与植被、建筑用地之间存在明显的相关性.

| Abstract: | Urban Heat Island (UHI) effect is an important feature by the impact of urbanization on urban environment. In order to study the changes of the impact of urbanization processing of Zigong city on UHI effect during the past 10 years, TM data and GIS method were employed to quantitative analyze temporal and spatial variation of urban land surface temperature of study area. According to the two-phase landsat TM images of 2000 and 2009, land surface temperature and land cover information of the study area were acquired, and the relationship between the spatial and temporal variation of heat island and changes of vegetation and building land were studied. Results show that there is an obvious correlation between the land surface temperature and land cover of the city. |
