建设低碳生态城市群是实现中国城市可持续发展的必由之路。低碳生态城市群的人居环境,应形成“四层一核心”,即居住环境(第一层)、社区环境(第二层)、城市环境(第三层)和城市群环境(第四层)四层及其核心“人”的空间层次结构。低碳生态城市群与宜居性二者的关系,具有共同的出发点与落脚点及建设主体的一致性,而且前者是后者的载体,后者是前者的目标之一。低碳生态城市群人居环境是一个复杂的巨系统,它具有空间结构的多维性、涵盖内容的多样性、提升的约束性、目标的确定性、优化路径的清晰性及建设的动态性等特征。

Abstract:Facing the problems of global climate change and the population,resources and environment,China must modify the existing urban development pattern and build the conserving resource and friendly environment city.Thereby,low carbon eco-agglomeration is the only way to achieve sustainable development for Chinese cities.The concept of the low-carbon was firstly introduced.Based on the definition and analysis of low carbon eco-agglomeration,it also states the relationship between the low carbon eco-agglomeration and the livability,and proposes“the four Layers-one Core”hierarchy of human settlements of low carbon eco-agglomeration.Then,its characteristics and tentatively constructs evaluation index system for the livability of low carbon eco-agglomeration are analyzed in order to provide a reference and guidance to upgrade the livability,a theoretical support to improve and optimize for the human settlements even successfully guides the urban group towards the low -carbon and ecology.

进入21世纪,人类面临着资源耗竭、能源短缺以及气候变暖等全球化问题。有效应对全球气候变化,消减CO2排放量,已经成为世界各国的共识。城市是碳排放最主要的集中地,而城市群又是当今区域城市集合体参与全球竞争的主体,构建低碳生态城市群是实现城市可持续发展的必由之路。
一 关于“低碳”和低碳生态城市群
(一)“低碳”的概念
在应对全球气候变化的背景下,“低碳”概念应运而生,继而“低碳经济”、“低碳社区”、“低碳城市”以及“低碳城市群”等新概念也相继出现。……
