摘　　要：以2011年、2015年、2016年Landsat影像为数据源,采用单窗算法反演地表温度,运用GIS和景观分析工具,分析了两江新区城市热力景观格局演变。结果表明,2011—2016年,两江新区城市热岛效应逐渐加剧,高温区域持续扩大,广泛分布于南部老城区、中部空港片区、西北部水土片区和东部龙兴-复盛片区,并逐渐呈连片分布趋势。热力景观变化以中温区和次高温区变化为主,变化总面积为705.41 km^(2)。同时,2011—2016年两江新区热力景观的数量特征、形态特征和结构特征均发生显著变化。景观破碎化程度降低,斑块类型逐渐单一化,景观蔓延度和连通度逐渐升高,城市热岛逐渐高强度化和集中化,并以东部龙兴-复盛片区表现最明显。Taking the images of 2011,2015and 2016 as the data source,this study analysed the evolution of urban thermal landscape pattern in Liang Jiang New Area by using GIS and landscape analysis tools.Results showed that the urban heat island effect of Liang Jiang New Area was intensified gradually from 2011 to 2016.And the high temperature area was gradually expanded and showed the characteristics of concentrated contiguous distribution.It was mainly distributed in southern old town,the central airport area,the northwest water and soil area,the eastern Long xing-Fu sheng area.The change area was 705.41 km^(2) mainly in the middle temperature area and the secondary high temperature area from 2011 to 2016.Meanwhile,the thermodynamic landscape of Liang Jiang New Area has changed significantly in quantity,form and structure.It showed that the landscape has been reduced the overall degree of fragmentation,the patch type has been simplified,the extension and connection of patch has been gradually increased.And the urban heat island effect gradually intensifies and centralizes,especially in the eastern Long xing-Fu sheng area.
