| 摘 要： | 以Landsat TM影像为数据源研究徐州市市区地表温度与植被指数的关系。研究表明,徐州市的地表温度存在明显的中心城区高、郊区低的热岛效应。而徐州市的归一化植被指数则表现为城市中心区总体偏小,植被覆盖较低。除水体外,植被指数与地表温度有明显的负相关关系。植被覆盖越高,地表温度越低,反之,则地表温度越高。

| Abstract: | The relationship between land surface temperature(LST)and vegetation index in the urban of Xuzhou City was studied by using Landsat TM images as the data source.The results showed that the surface temperature of Xuzhou City was high in the center of Xuzhou city and low in the suburbs with urban heat island effect.At the same time,the normalized difference vegetation index(NDVI)showed that the vegetation coverage was low in the center of Xuzhou.Except water,vegetation index and surface temperature had a sign... |
