摘要:
量化分析城市形态空间格局与城市热环境的关联关系,将有助于提升城市规划与设计中形态管控的合理性,对于改善城市热环境和促进城市可持续发展等具有重要的意义. 本文以南京市为案例,对其复杂城市形态的空间格局进行量化,并探究其与城市热环境之间存在的关联性. 主要结论如下:(1)空间滞后模型更适用于城市热环境关联的研究,且城市热岛强度(UHII)受到周边区域强度的正向影响.(2)分季节来看,城市形态空间格局对UHII的影响排序为春季>夏季>秋季>冬季.(3)所有的建成环境形态类型和LCZ E(空地)在周边环境中的数量占比在多数季节中均会对城市热环境产生显著的正向升温影响,其中LCZ 8(低层大体量建筑)的数量占比的影响程度最大. 而自然环境形态类型则多有利于降温,LCZ G(水体)的作用优于LCZ A(树林).(4)从整体布局上看,周边由单一形态主导的空间格局将有助于带来更低的UHII.(5)以空间格局指标为依据,可以将研究区域分为9类具有相似形态组成结构和周边环境特征的分区类型. 不同类型间存在热环境属性差异,应采取差异化的手段对其进行调控. 研究结论可为构建气候适应性城市提供参考.
Abstract:
Quantitative analysis of the correlation between the spatial patterns of urban form and the urban thermal environment will help to improve the rationality of morphological control in urban planning and design,which is important for improving the urban thermal environment and promoting sustainable urban development. Taking Nanjing as an example,this paper quantifies the spatial patterns of the complex urban form and explores the correlation with the urban thermal environment. The main conclusions are as follows:(1)The spatial lag model is more applicable to the study of urban thermal environment association,and the urban heat island intensity(UHII)is positively influenced by the UHII of the surrounding environment.(2)By season,the impact of the spatial patterns of the urban form on UHII is ranked as spring>summer>autumn>winter.(3)The proportion of all built environment form types and LCZ E(ground)in the surrounding environment have a significant positive effect on the urban thermal environment in most seasons,with the proportion of LCZ 8(large low-rise buildings)having the greatest degree of positive influence. In contrast,the natural environmental form type is mostly conducive to cooling,where LCZ G(water)is better than LCZ A(forests).(4)In terms of the overall layout,the spatial patterns of the surrounding environment dominated by a single form will help bring about a lower urban heat island intensity.(5)Based on the spatial pattern indicators,the study area can be divided into 9 zoning types with similar morphological composition structures and characteristics of the surrounding environment. Differences exist among types in thermal environment properties,which should be regulated by differentiated means. The conclusions of the study can provide a reference for the construction of climate-resilient cities.
