轨道交通时代下的类莲蓬理想城市模式构建——兼论长沙市城市发展模式的转型

Ideal Model of Analogous Lotus City Establishment in Rail Transit Era——Transformation of Changsha City Development Model

轨道交通是城市发展到一定规模后的产物,必将成为触发中国城市建设颠覆性革命的导火索。尊重中国城市化多为"中心城市"的既定事实,回顾国内外轨道交通建设以来城市转变的百年历史,致力研究轨道交通时代背景下具备两型特色的未来城市转型理念。首提类莲蓬理想城市模式构想,内容涉及城市形制调整、功能布局优化、空间景观改进、生活理念转变等方面,力求形成紧凑型城市功能组织架构,大幅度提升城市土地利用集约度,完美融合都市"密景观"与田园"疏景观",形成层次丰富、快慢有序的"城+乡"生活体。现以初涉轨道交通时代的长沙城市为例,提出其朝类莲蓬城市模式转型的规划方法,为其他城市提供借鉴。
