摘要
提出了“城市基因改造论”和“畅通城市新模式”。目前城市“有机体”中存在着致病基因———“空间错位”,正是这一致病基因,导致产生了影响城市可持续发展的十大问题:城市占地多、效率低、能耗高、污染重、停车难、治安差、不宜居,以及交通事故多、交通投资巨大等。城市交通问题应该从“城市交通-城市空间-经济-社会”四个层次综合研究,“跳出交通看交通”,铲除“空间错位”这个基因,才能一揽子解决城市交通和城市可持续发展的诸多问题。通过分别构筑车与人的空间,将一个混乱的城市空间变为两个自由空间,从而构建“畅通城市新模式”,既可实现《雅典宪章》所提出的寻找新的街道系统以适应汽车交通特性[1],又可实现建设“以人为本”节约宜人型城市的新目标。
This paper puts forward ＂Ideas on Reforming City Gene＂ and ＂New Smooth City Mode＂. At present, city suffers from fatal gene--＂misplaced space＂, which leads to ten serious problems hindering city sustainable development： occupation of too much city land, low efficiency, high energy consumption, heavy pollution, great difficulty in parking, poor public security, uncomfortable living environment, .frequent occurrence of traffic accidents and huge amount of transportation investment. It is better to carry out study from perspective of 4 levels of ＂city transportation--city space--economy--society＂, locate transportation problems from other point of view instead of from transportation, and get rid of gene of ＂misplaced space＂. Only by this way, can many problems concerning city transportation and sustainable development get solved completely. A disordered city space can be separated into two free spaces by constructing one for cars and one for people respectively, thus constructing a ＂New Smooth City Mode＂. The new mode can realize goal of finding new street system to adapt to characteristics of car transportation as put forward by ＂Athens Charter＂ as well as target of building saving and pleasant ＂human-oriented＂ city.
