| 摘 要： | 以大连市区建筑数据、SPOT 5和Landsat 8遥感数据为基础，运用局部气候带分类、地表温度反演方法，研究大连市局部气候带分区类型和特征，进而分析不同局部气候带对城市地表温度的影响。研究结果表明：①大连市建筑类型高度主要为低层建筑、多层建筑和中高层建筑，建筑密度为中密度和较高密度，甘井子区分布大量森林绿地，中山区具有丰富的公园绿地；②地表温度整体偏高，空间上呈现东高西低的趋势，其中半数以上地区地表温度达到28℃~31℃，并且有超过1%的地区地表温度大于38℃，该区域出现极端高温；③同一建筑高度上，密度越大的建筑区域，地表温度越高；同一建筑密度，多层建筑高度覆盖区地表温度较高。森林绿地地表温度最低，公园绿地和社区绿地地表温度几乎一致，附属绿地地表温度最高。

| Abstract: | Based on Dalian urban building data, SPOT 5 and Landsat 8 remote sensing data, using local climatic zone classification and land surface temperature inversion method to study the regional zoning types and characteristics of Dalian, and the impact of different local climatic zones on urban surface temperature. The research results show that the height of building types in Dalian are mainly low-rise buildings, multi-storey buildings and medium-rise buildings. The building density is medium density and high density. The Ganjingzi District is distributed with a large number of forest green areas, and the Zhongshan District is rich in park green space. The surface temperature is generally high, and the space is east to west and low. The surface temperature of more than half of the area reach 28~31℃, and the surface temperature of more than 1% is greater than 38℃, indicating that the region has extreme high temperature. At the same building height, the higher the density of the building area, the higher the surface temperature; the same density building, the multi-storey building coverage area has a higher surface temperature. The surface temperature of forest green space is the lowest, the surface temperature of park green space and community green space is almost the same, and the surface temperature of the auxiliary green land is the highest. |
