A Study on the Urban Renewal Projects by Area Management ---Focusing On Open Space by Plaza ＆ Bonus System

1.通过对日本、瑞士、德国、英国等国的城市更新项目进行案例调查和对现有数据的分析，发现网络、愿景、公民参与过程、环境关怀等是城市更新项目区域管理的重要因素。土地用途、设计指引、休憩用地质素、地区特色、区域环境。在本分析中，我们比较了以下工业用地的市区重建项目的地区管理：东五反田和丰洲（东京），MM 21，港口边，与银行艺术计划一起（横滨）、前贺（千叶）、中央区（川口）、西苏黎世、北苏黎世（苏黎世）、苏尔寿地区、苏尔寿公园（温特图尔）、SIG（诺伊豪森）、德雷斯皮茨地区（巴塞尔）。为了发现市镇中心强化项目对市镇管理组织的问题和挑战，以改善地区管理，我们调查了佐贺市的情况。因此，有必要采取自下而上的办法，与包括本国专业干事在内的不同组织合作。对曾经有过城市更新项目的城市进行了问卷调查。在回答问卷的193个城市中，有10%的城市有区域管理组织，但大多数城市认识到任何区域管理的重要性。通过这些案例研究，明确了以下问题对城市更新项目区域管理的重要性：1）具有灵活和动态规划的一致性管理系统; 2）对环境和城市生态网络的贡献; 3）产生公私合作伙伴关系和网络的社会过程; 4）背景身份和创造力。
