A Case Study on the Urban Regeneration Policy with Environmental Symbiosis in Foreign Countries

本研究探讨了环境共生下的城市更新政策。本研究的目的是探讨国外城市更新的良好实践，并确定可持续城市形态的成功因素。这项研究的目标是发达国家和发展中国家的许多城市。我们调查了国家层面的城市和环境政策，并调查了城市层面的城市重建的良好做法。通过对比分析，对所有案例进行评价，重点关注我们的研究观点，如吸引力、规模和集聚在城市再开发中的作用、公共和私营部门的关系、城市公共交通系统和城市环境政策。我们发现了城市再生的成功因素，如私营部门的领导、公民的参与、城市发展的放松管制、战略规划、区域资源的利用和伙伴关系。将这些因素分为三大类，即在城市中心区域形成公共空间，有效利用当地资源，选择最优的环境治理技术以实现城市的可持续发展。在发达国家，为了实现可持续发展的城市，循环利用、节能、环保和共生是重要的关键词。紧凑型城市将是一种可持续的城市形态。湖泊流域的环境管理应纳入城市更新框架。在发展中国家，一些城市在城市更新方面有良好的做法，但在环境方面却很少有良好的做法。综上所述，要实现可持续的城市更新，我们应该更多地关注空间层面的环境共生。在今后的研究中，城市更新政策与流域湖泊环境管理应保持协调一致。少

This study explores case studies on the urban regeneration policy with environmental symbiosis. The purpose of this study is to investigate good practices of the urban regeneration in foreign countries and to ascertain the successful factors for the sustainable urban form.This study targets many cities in developed and developing countries. We survey the urban and environmental policies at the national level and investigate good practices for the urban redevelopment at the urban level. All the case studies are evaluated by the comparative analysis focusing on our research viewpoints such as the role of attractiveness, scale, and agglomeration in the urban redevelopment, the relationship between public and private sectors, the urban public transportation system, and the urban environmental policy.We find out successful factors for the urban regeneration, such as leadership of private sector, civil participation, deregulation for urban development, strategic planning, utilization of regi … More onal resources, and partnership. Those factors are classified into three categories, i.e., to form public space in the central area of city, to efficiently utilize the local resources, and to choose the optimal environmental abatement technology for the urban sustainability.For achieving a sustainable city in the developed countries, recycling, energy-saving, environmental abatement, and symbiosis are picked up as important keywords. The compact city will be a sustainable urban form. We also find out the environmental management on the lake and basin areas should be incorporated into urban regeneration framework. In the developing countries, several cities have good practices of the urban regeneration but there are few good practices of the environmental aspects.In conclusion, we should pay more attention to the environmental symbiosis at the spatial level for achieving a sustainable urban regeneration. The urban regeneration policy and the environmental management for basin and lake should be harmonized for our future study. Less
