【摘要】 近年来,我国的城市化进程快速推进,城市建筑体量迅速增加,城市建筑布局不断改变,热岛效应日益加剧,而建筑密度作为影响热岛效应的主要因素之一,当前对两者关系的探讨较少。文章以天津市为例,基于3S技术、高精地图数据和高精测试仪器等,利用Arc GIS、MATLAB和SPSS数据分析平台,定量研究建筑密度与夏季热岛的尺度响应机制及防控参数,明确建筑密度与热岛强度的时间与空间尺度敏感性,由此提出在城市规划建设中,应根据建筑密度对热岛强度的削减量化机制构建削减热岛强度的建筑密度等级体系,为城市规划建设中的热岛防控提供应用基础研究。更多还原

【Abstract】 Fast urbanization has resulted in a dramatic increase of building volume and change of building layout, and exacerbation of hot island effect. Building density is a major factor that impacts hot island effect. With Tianjin city as a study case, aided by 3D technology, high resolution map data, Arc GIS, MATLAB, SPSS analysis tools, the paper conducts quantitative study on building density, response scale and control parameters of hot island effect, and studies the space-temporal sensitivity of building density and hot island effect. The paper proposes quantitative and leveled building density measures to prevent and control hot island effect.更多还原
