| 摘 要： | 本文利用2006年、2010年沈阳市地区TM遥感数据,采用影像IB算法反演地表温度,分析了沈阳市热岛效应的空间分布特征、变化现象以及地表温度与归一化植被指数(NDVI)、归一化建筑指数(NDBI)之间的相关性。研究表明沈阳市热岛效应总体呈现由市中心向四周逐渐扩张的空间特征,地表温度与归一化植被指数(ND-VI)存在紧密的负线性相关关系,地表温度与归一建筑指数(NDBI)存在正相关关系。

| Abstract: | By the 2006,2010 TM remote sensing data of Shenyang City region,the image IB algorithm was used to retrieve land surface temperature,the urban heat island effect of Shenyang City was analyzed with the spatial distribution characteristics,change phenomenon and the correlation between land surface temperature,vegetation index(NDVI) and normalized building index(NDBI).Studies showed that the urban heat island effect in Shenyang City gradually expands from the town center to around the land surface temperature and NDVI has a close negative linear relationship,while there is a positive correlation between the land surface temperature and NDBI. |
