【摘要】：下城是一座城市的心脏。然而,随着美国城市郊区化进程的发展,下城的城市地位日益下降,一系列社会问题随之而来,下城中充斥着暴力、混乱、贫穷、污染等严重问题,已然成为了衰败的代名词。尽管城市管理者实施了一系列再开发政策以促进下城振兴,但直至二十世纪下半叶,大多数美国下城仍旧存在严重的经济问题和令人堪忧的发展前景,下城衰落的窘况未有明显好转。可幸的是,二十世纪末期信息化技术的发展为下城再开发带来了契机,着重于发展高科技服务业的下城能够在大都市区中起到更为专业性的作用。得益于信息化发展,这一时期的下城再开发策略实施已然有了明显的积极效果,譬如建筑的新增和再利用、改善交通运输条件、购物中心建设、步行区建设、滨水区再开发及历史遗迹保护等再开发策略,在城市空间整合、交通通达性和容纳性提升以及综合性经济中心建设方面都有所改善,许多城市下城一改之前颓废的状态,重新焕发生机。然而,进入新世纪以来,部分再开发策略逐渐暴露出了弊端,有些策略不再适合下城再开发建设、有些策略则需要加以完善才能适应下城现状。因此,城市下城的再开发之路仍旧任重道远。
[Abstract]:The lower city is the heart of a city. However, with the development of suburbanization in the United States, the status of the city is declining day by day, and a series of social problems follow. The city is full of violence, chaos, poverty, pollution and other serious problems, which has become a synonym of decline. Although city managers implemented a series of redevelopment policies to promote the revitalization of the city, until the second half of the twentieth century, most of the lower cities of the United States still had serious economic problems and worrying prospects for development. The plight of downtown decline has not improved significantly. Fortunately, the development of information technology at the end of the 20th century has brought the opportunity for the re-development of the city, focusing on the development of high-tech services can play a more professional role in the metropolitan area. Thanks to the development of information technology, the implementation of the strategy of redeveloping Xiacheng in this period has already had obvious positive effects, such as the addition and reuse of buildings, the improvement of transportation conditions, the construction of shopping centers and the construction of walking areas. Redevelopment strategies such as waterfront redevelopment and historical heritage protection have improved in terms of urban spatial integration, traffic accessibility and accommodation, as well as the construction of comprehensive economic centers. Many cities have been decadent before the reform of the city. Rejuvenate. However, since the beginning of the new century, some redeveloping strategies have gradually exposed some disadvantages, some of which are no longer suitable for the redevelopment and construction of the lower cities, and others need to be perfected to adapt to the present situation of the lower cities. As a result, the road of redevelopment of the city is still a long way to go.
