【摘要】 改革开放以来,我国的城市化水平得到了快速发展。可是在这高速的城市化背后,却存在着诸多不可持续的发展现象。社会经济的提升往往以牺牲城市生态安全为代价,生态用地被蚕食、生态结构被破坏、生态环境被污染,极大限制了城市未来的进一步发展。然而,城市规划作为引导城市和谐发展的主要手段之一,却因缺乏对城市规划实施后的生态安全进行评价,未能及时提出改善生态体系的调控策略,从而处于尴尬的地位。从而使得城市的建设陷入了恶性循环的发展轨迹。文章首先阐述了目前我国城市规划体系所面临的问题,以及由这些问题产生的严重后果,再通过对国内外城市规划实施评价与生态安全评价研究相关理论和方法的整理,总结出一套针对城市规划实施后生态安全评价的指标体系,并以重庆市北部新区为例进行评价分析。基于北部新区的评价结果,探索城市规划实施的生态实效机制,其中包括失效机制和成效机制的研究,力求从城市规划三大体系中寻找城市规划实施生态安全失效的本质原因,从实施的过程及结果总结实施的成效经验。总结研究成果,最终落实到空间要素中,针对北部新区构建生态安全格局,以此为依据,提出以问题为导向及以目标为驱动的空间调控策略,并对下一轮规划的指导建议。城市生态安全的缺失已经成为中国快速城市化过程中不能再回避的问题。文章希望通过城市规划实施的生态安全评价体系、实效机制以及空间调控策略的研究,探索一条引导城市可持续发展的道路,使得城市规划学科能真正引导城市和谐发展。更多还原

【Abstract】 With the reform and opening up, China’s urbanization level has developed rapidly. But behind this high-speed urbanization, there are many unsustainable developments. The enhancement of social economy is often at the cost of ecological security in city, e.g. ecological land is eroded, the ecological structure is destroyed and the ecological environment is polluted, which greatly limited the city’s future development. And urban planning, as the main means to guide the city to the harmonious development, failed to put forward adjusting strategy timely to improve the ecological system, for lacking of make commenting on ecological safety after the implementation of urban planning. Then make city construction fall into a vicious circle.This paper describes the problem on current system of urban planning in China and the serious consequences of these problems, by summing-up the theory as well as methods about urban planning implementation and ecological security assessment among western countries and China, summarizes a set of indicator system for post-urban planning implementation, finally make evaluation analysis with Chongqing New North Zone as an example. Based on the evaluation result of Chongqing New North Zone, this paper analyzes the implementation mechanism on ecological security during urban planning implementation, including the failure mechanism and the effective mechanism, and trying to find out the reason of the failure of the implementation mechanism on ecological security from the point of the three major urban planning system, then summarize effective experience by the implementation process and results. At last this paper summarizes the research results, focusing on the space element, then according to ecological security patterns in Chongqing New North Zone, it also puts forward space regulation strategy, building ecological structure and guidance for the next round of planning proposals.In a word, the lack of city ecological security has become a tricky problem in process of rapid urbanization in China. This paper tries to explore a road for city Sustainable Development, which bases on the study of urban planning implementation, ecological security assessment, implementation mechanism and space regulation strategy, then make Urban Planning serve for harmonious city development indeed.更多还原
