摘要: 以大连市中山区的遥感和建筑等多源数据为基础,结合单窗算法和相关分析方法,研究分析了2002—2014年研究区的地表温度空间分异特征及地表温度与建筑密度的相关性。研究结果表明:①2002—2014年地表温度高温区域多分布在中山区西北部、解放路和中南路的沿线,且温度增加明显,东北部由于填海造陆温度明显升高;②高密度和较高密度的地块主要分布在青泥洼天津街商业区,大部分低、较低、中密度地块分布在解放路和中南路沿线;③2002年、2014年,地表温度与建筑密度呈现中等相关性,相关系数分别为0.514、0.537。

关键词: 地表温度, 城市热环境效应, 城市建筑水平特征, 建筑密度, 相关分析

Abstract: The correlation of spatial variation in surface temperature with building density in Zhongshan district,Dalian city is investigated over the period 2002-2014.This paper utilizes remote sensing data and multi-source land use data,which evaluates using a combination of single-window algorithm and correlation analysis.The results show that during 2002-2014,most of the high-temperature grid cells distribute along Jiefang Road and Zhongnan Road and thenorthwest part of Zhongshan district,and the temperature increases obviously.The temperature increases significantly after an area of land in the northeastern part of the district is reclaimed from the ocean.The high density and relatively highdensity plots are distributed mainly in the commercial district of Qingniwa-Tianjin Street.Most of the low density,relatively low density,and mediumdensity plots are distributed along Jiefang Road and Zhongnan Road.Surface temperature shows moderate correlation with building density (0.514 and 0.537,in 2002 and 2014,respectively).

Key words: surface temperature, heat island effect, architectural horizontal characteristics, building density, correlation analysis
