摘　　要：全球气候变暖大背景叠加快速城镇化,导致城市地区面临城市热岛、通风不畅等一系列生态问题。蓝绿空间在缓解城市热岛效应、降温等方面具有重要意义。针对国土空间全域,搭建局地气候分区与国土空间用地、用海分类框架,借助陆地卫星8号反演和GIS空间分析工具,对全域地表温度进行量化分析,研究城市热岛空间分布特征与城镇化连绵发展态势的关联性,以及城市热岛、冷岛分布的空间相关性规律。结合郑州市典型案例,从热岛缓解视角,研究蓝绿空间的降温幅度和降温效果与空间区位、布局及用地面积规模阈值的关系,采取科学、有效的措施降低城市热岛效应,从全域、全要素,布局结构优化和实施重点管控三个维度提出响应策略。Global warming encountered by this generation intensifies urbanization process,as a result,urban areas now are faced with a series of eco-problem such as urban heat island(UHI),poor ventilation,etc.Therefore,this is where blue-green space is introduced to mitigate UHI effect and cool the atmosphere.Targeting the entire territorial space,applying Landast 8 satellite retrieval and GIS spatial analysis tool to quantify and analyze the surface temperature based on a comprehensive perspective,where local climate zoning framework,and land and sea use classification for territorial spatial framework are established for demonstration.Study the correlation between the spatial distribution characteristics of UHIs and the continuous development trend of urbanization,as well as the spatial correlation law of UHI and cold island distribution.Based on a typical case study in Zhengzhou,this study investigates the relationship between the cooling amplitude and cooling effect of blue-green spaces and the threshold values of spatial location,layout,and land use size from the perspective of heat island mitigation.Furthermore,the study aims to scientifically and effectively reduce the UHI effect,and propose response strategies from three dimensions:overall factors,optimization of layout structure,and implementation of key control measures.
