摘要
基于landsat8遥感影像,定量提取了城市发展中重要的遥感指数NDBI、NDVI与MNDWI并反演LST,分析了3种遥感指数与LST之间的相关性;对2001年与2016年的LUCC进行了对比分析,并对不同LUCC之间的遥感指数分布进行研究。结果表明,NDBI代表的建筑用地越密集,LST数据越高,NDVI代表的林地覆盖越密集,LST数据越低,可为研究城市热岛效应提供相应依据。
Based on the landsat8 remote sensing image,the important remote sensing indices NDBI,NDVI and MNDWI in urban development were extracted and the LST was retrieved. The correlation between the three remote sensing indices and LST was analyzed,the LUCC in 2001 and 2016 were compared. The distribution of remote sensing index between different LUCCs were analysed. The results showed that the denser the construction land represented by NDBI, the LST data was higher,the denser the forest land cover represented by NDVl, and the LST data was lower,it could provide a basis for studying the urban heat island effect.
