摘要
以TM影像为数据源,采用遥感和地理信息系统技术研究了重庆市主城区不同景观表面温度的差异及其与植被指数之间的关系。研究表明,重庆市主城区存在明显的热岛效应,城市干线对热岛的空间分布具有很大影响;不同城市景观的表面温度存在显著差异;城市地表温度与植被指数具有大致相反的空间分布规律。
With TM image as data resource, the differences of surface temperature of different urban landscapes and the relationship between their surface temperature and vegetation index in main urban area of Chongqing were studied with the technology of remote sensing and geographic information system. The results showed that the obvious thermal island effect existed in main urban area of Chongqing, and the urban trunk had great effect on the distribution of thermal islands. The surface temperature of different urban landscapes had significantly differences. The spatial distribution law of urban surface temperature was approximately contrary to that of vegetation index.
