摘　　要：选取龙口地区为研究对象,利用Landsat TM遥感数据根据像元灰度值与地表亮温的相关关系反演了快速城市化的典型地区龙口市的城市地表温度并计算其植被指数。通过线性相关分析,发现了地表温度与植被指数呈显著的负相关性关系。结果表明:城市绿化可有效缓解城市热岛效应。Selecting Longkou region as the research object,this article inverts urban surface temperature of Longkou which is the typical region of rapid urbanization according to the correlation between the pixel gray value and the surface brightness temperature and then calculates the vegetation index. The results show that it is a significant negative correlation relationship between surface temperature and vegetation index by linear correlation analysis. Therefore, it is proved that the urban greening can effectively alleviate the urban heat island effect.

关 键 词：热岛效应 植被指数 地面亮温 相关性
