健康城市视角下城市滨江高架桥下空间更新初探--以重庆市嘉滨路为例

Study on Space Renewal Underneath the Riverside Viaducts from the Perspective of Healthy City:Taking the Chongqing Jiabin Road as an Example

城市交通高架下部的空间是典型的具有利用价值的“都市空缺”,是当前健康城市优化发展中无法绕开的一个话题。而重庆嘉滨路高架桥下空间又是其中最为特别的一例,由于独特的地理环境特点,其除了具有普通的城市高架下“负空间”所具有的问题之外,还面临着可达性差,地形陡峭,消落带水位周期性大幅消涨等问题。但又正是这些地理环境特点使其具有独特的景观开发潜质,若以合理手法激活改造,便能“变负为正”。本文深入探究其失落之因,从空间特质,区位优势以及市场趋势三方面分析其激活潜质,结合重庆市宏观的旅游现状,从活动多样性、易达性、整体性,以及时空灵活性四方面提出对应的激活策略,构造出一条区域联动的,独具“山城烟火气”的旅游走廊。

The space underneath the urban viaducts is the typical“Urban Voids”and it is also an important issue which is unable to avoid in the city development.The riverside via-ducts in Yuzhong district of Chongqing is one of the most special cases.Besides problems shared with those ordi-nary urban viaducts,it also confronted with the challenges of poor accessibility,steep terrain and a severe water-level fluctuation zone,etc.However,it is exactly those challeng-es that makes it have the unique landscape potential to be explored.This thesis combines the general situation of the tourism in Yuzhong district,introducing the“vending econ-omy”,responding the periodicity with flexibility,to stimulate its potential,and create an interconnected travel corridor with the atmosphere of the local bustle secular life.
