随着近30年的城市高速发展,我国大部分城市城市建成面积已经扩大为30年前的几倍有余,城市用地的匮乏和自然环境的恶化成为当前城市化的一个突出矛盾的,同时原来的旧城区随着急剧的城市变化和扩张受到了很大甚至是毁灭性的破坏。因此在未来的我国的城市发展存在一个必须要协调和平衡好的一对矛盾:一方面城市已不能随意进一步向四周扩张,必须盘活现有建成区的土地和合理提高建成区的城市承载力,另一方面旧城在目前普遍破坏的基础上需要进一步的维护更新,尽量维持日益消失的城市特色。当今中国不少城市正面临这样一种矛盾,如何处理好城市发展与保护、新与旧的关系成为一个关系当前城市发展的重要课题。
With the rapid development of the cities in recent 30 years, the completed area of most cities in our country has been expanded to more than 30 years ago. The lack of urban land and the deterioration of the natural environment have become prominent contradictions in urbanization at the same time. The old city has been greatly or even destructively destroyed with dramatic urban changes and expansion. Therefore, there is a contradiction that must be reconciled and balanced in our country’s urban development in the future: on the one hand, the city can no longer expand to the surrounding area at will; it must revitalize the existing built-up areas and rationally enhance the urban carrying capacity of built-up areas, On the other hand, the old city needs further maintenance and renewal on the basis of the current widespread destruction so as to maintain the disappearing urban characteristics as much as possible. Many cities in China today are facing such a contradiction. How to deal with the development and protection of cities and the relationship between new and old cities has become an important issue concerning the current urban development.
