摘要
城市空间形态对城市微气候环境的影响一直受到学界及规划管理部门的关注。以武汉市主城区589个控规管理单元为样本,运用RS—GIS的技术方法识别热岛空间格局,采用多元线性回归模型揭示热岛空间分布的影响要素。研究发现:武汉主城区地表温度由中心向外围存在规律性起伏,呈现“双U”型结构;高温区团块集中、沿主干路分布,低温区在大尺度水体周边集中分布;热岛空间格局受“大江大湖”的生态格局以及大规模集中工业用地的显著影响,并与公共中心体系相关。为降低热岛效应,城市空间布局应采取相应对策。
The impact of urban spatial form on urban microclimate has always been the focus of academia and planning administration departments.Taking 589 zoning units in the main city of Wuhan as a sample,RS-GIS technology and multiple linear regression models were adopted to identify the spatial layout and influencing factors of the spatial distribution of urban heat island (UHI).The study found that the land surface temperature (LST) of the main urban area of Wuhan regularly fluctuates from the center to the periphery,showing a "double U" structure;the high temperature areas are concentrated and distributed along the main road,and the low temperature area are concentrated around the large scale water body;the spatial layout of UHI is significantly impacted by the ecological pattern of “Great Rivers and Great Lakes” and forward in this paper.
