摘要/Abstract

摘要：植被对城市热场具有调节作用，城市热场的分布和强度与归一化植被指数（NDVI）有密切的联系.通过对城市热场与植被指数（NDVI）相关性的研究，可以揭示它们的空间分布特征，反映城市空间结构和城市生态环境的发展变化.基于ARCGIS和ARCVIEW软件，使用GIS空间分析方法，从2003年上海市TM影像中计算提取上海市外环线以内区域的城市热场与植被指数（NDVI）的相关信息，建立城市热场与植被指数(NDVI)的回归拟合方程，对二者的关系进行分析.结果表明，城市热场与植被指数（NDVI）呈负相关关系.

Abstract: Vegetation can adjust the urban thermal distribution,and there is a consanguineous connection about distributing and intensity of urban thermal distribution and NDVI.The research of the relationship between urban thermal distribution and NDVI will find their spatial distributing characters and reflect the change of urban spatial structure and urban entironment.Base on the softwares ARCGIS and ARCVIEW,use spacial analyst technique of GIS,calculate and distill information about urban thermal distribution and NDVI which locate the area within outside ring road of Shanghai City from TM images of Shanghai,2003,build the regression approach equation of urban thermal distribution and NDVI,and do analysis on the relationship between urban thermal distribution and NDVI.The result indicates that the relationship between urban thermal distribution and NDVI is minus correlation.

Key words: urban thermal distribution, NDVI, remote sensing, spatial analysis, Shanghai City
