基于TM影像的徐州市城市热岛效应分析
nalysis of Urban Heat Island over Xuzhou from TM Data
作为地球系统科学中的重要组成部分,地表温度与城市的热岛效应有着密切的关系。对地表温度与植被生长状况的之间关系进行研究,对于缓解城市的热岛效应有一定的指导意义。选择徐州地区为研究对象,采用Landsat TM6数据,利用单窗算法计算地表温度,对徐州地区的热岛分布进行模拟,结果表明,徐州市区呈现明显的热岛现象,且地表温度呈现出从城市中心向外逐渐降低的趋势。对地表温度和NDVI进行相关性分析,两者呈现明显的负相关关系,植被茂盛的地方地表温度低,反之亦然,植被能够起到降温的作用。
s an important component of Earth System Science, there is a close relationship between Land Surface Temperature (LST) and Urban Heat Island. The research of relation between Urban Heat Island and vegetation growth status has great significance in mitigation of Urban Heat Island.By taking Xuzhou as research object, mono-window algorithm was used to calculate surface temperature by using Landsat TM6 data and simulated the distribution of Urban Heat Island. Experiment results showed that Xuzhou City present obvious urban heat island. By the analysis of correlation between surface temperature and NDVI, the results proved a significant inverse correlation,LST was low in flourish vegetation. Vegetation can decrease temperature.
