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。
In recent years, the process of urbanization in our country has been advancing rapidly, the volume of urban architecture has been rapidly increasing, the layout of urban buildings has been changing, and the heat island effect has been aggravated day by day. However, as one of the main factors that affect the heat island effect, less. Taking Tianjin as an example, this paper uses ArcGIS, MATLAB and SPSS data analysis platform to quantitatively study the scale response mechanism and control parameters of summer heat island based on 3S technology, high-precision map data and high precision test equipment. Building density and heat island intensity of time and space scale sensitivity, which proposed in the urban planning and construction, should be based on the intensity of construction of urban heat reduction intensity reduction mechanism to build thermal insulation strength of the building density grade system, for the urban planning and construction of the heat island Prevention provides basic applied research.
