本文以武汉三镇为研究对象，利用2009年夏季Landsat TM主要遥感数据源，进行地表温度反演和土地覆盖解译，计算了武汉市城市建筑指数NDBI、归一化植被指数NDVI；并利用NDVI计算地表比辐射率，并使用单窗算法精确反演得到了武汉市2009年夏季地表温度LST。研究结果表明：武汉城市热岛由武昌、汉口、汉阳三大城区热岛构成，且三镇交界区存在多数热岛效应更为严重的“岛中岛”，以汉口区中心商业区最为集中；进一步对植被覆盖区和建筑区温度及NDVI、NDBI相关性研究表明，武汉市不同土地覆盖类型有较大差异，LST与NDBI指数成正相关性，且相关系数建筑用地>植被>水体；LST与陆地表面NDVI指数成负相关性，且相关系数城市用地>植被，与水体NDVI指数成正相关性。
本文以武漢三鎮為研究對象，利用2009年夏季Landsat TM主要遙感數據源，進行地錶溫度反縯和土地覆蓋解譯，計算瞭武漢市城市建築指數NDBI、歸一化植被指數NDVI；併利用NDVI計算地錶比輻射率，併使用單窗算法精確反縯得到瞭武漢市2009年夏季地錶溫度LST。研究結果錶明：武漢城市熱島由武昌、漢口、漢暘三大城區熱島構成，且三鎮交界區存在多數熱島效應更為嚴重的“島中島”，以漢口區中心商業區最為集中；進一步對植被覆蓋區和建築區溫度及NDVI、NDBI相關性研究錶明，武漢市不同土地覆蓋類型有較大差異，LST與NDBI指數成正相關性，且相關繫數建築用地>植被>水體；LST與陸地錶麵NDVI指數成負相關性，且相關繫數城市用地>植被，與水體NDVI指數成正相關性。

In this paper, three towns of Wuhan are used as the research object, and Landsat TM in 09/2009 is use d as the main remote sensing data sources. Based on the land surface temperature interpretation after the processin g of image correction, the urban construction index NDBI and normalized difference vegetation index NDVI were calculated in the study area, meanwhile, the surface emissivity was counted by NDVI index and the single window algorithm was used to calculate the surface temperature in the summer of 2009 LST in the study region. The resea rch results show that the urban heat island in the summer of Wuhan consisted of three heat islands in Wuchang,Ha nkou and Hanyang city area, and there existed some more serious "island to island" of heat effect in the border ar ea of three towns, while it was more focus on the commercial center of Hankou. Further research on the relations hip of LST, NDVI and NDBI in the vegetation area and construction area showed that, there was a bigger differen ce in different land cover types of LST and NDVI, NDBI index: Correlation study shows there was a in positive correlation between city LST and NDBI index, and correlation coefficient of construction land>vegetation>water bod y.There was a negative correlation between city LST and NDVI index with the correlation coefficient of urban lan d>vegetation, while LST of water body existed positive correlation with NDVI index.
