城市三维形态与热环境的相关关系研究——以大连市金普新区为例

由城市各种实体空间结构所构成的三维形态是城市形态的重要组成部分。而城市的空间结构与城市空间环境的热场分布也有着密不可分的关系。本文运用地理信息系统与遥感技术,获取三维形态指标与地表温度,对各因子进行回归分析,建立城市空间形态热场分布研究的回归模型。分析了金普新区空间实体的占空度、错落度、建筑密度等空间形态对城市亮度温度的影响,发现占空度与城市亮温成正相关并且相关性较高,绿化率与亮温成负相关,而建筑密度与错落度对城市热场的影响较小。

A study of correlationship between the three-dimensional urban and urban thermal environment---A case study on JinPudistrict

By the urban spatial structure of various entities three-dimensional shape is an important part of urban form. And urban space structure and thermal field distribution of the urban space environment also has the inseparable relations. Geographic information system and remote sensing technology is used to obtain three -dimensional shape index and land surface temperature, regression analysis, for each factor to build the urban space morphology of thermal field distribution in the regression model. Analyzed Jin Pu new duty of spatial entities, strewn at random, building density and so on the influence of the spatial form of urban brightness temperature, found space and city bright WenCheng positive correlation and correlation is higher, covered with bright WenCheng negative correlation, and the building density and degree of strewn at random have less effect on the urban thermal field.
