城市滨水区再开发的生态、社会功能及文脉三维连接性分析

Analyses on three-dimensional connectivity of eco-social function-context of urban waterfront redevelopment

城市滨水区再开发常以提高"连接性"作为规划策略促进城市滨水空间转型,使城市焕发新的活力。根据系统论观点,通过分析城市滨水区连接性的建立层次,提出用三维向量来描述城市滨水区的连接维度,即第1维连接于生态、第2维连接于社会功能、第3维连接于文脉;给出适合于城市设计角度的城市滨水区连接性评价指标体系及城市滨水区连接度计算方法。以澳大利亚珀斯市滨水区两个典型的再开发案为研究对象,对比分析以景观修复和以城市开发为导向的两类城市滨水区再开发项目在城市滨水区连接度上的不同,并对它们在发挥功能和结构连接方面的差异进行了评测。

As a planning strategy,＂connectivity＂ has been used to promote the transformation of urban waterfront space to revitalize the city.According to the viewpoint of systematic theory,by analyzing the hierarchy of the connectivity of urban waterfront,it was suggested that the three-dimensional vector can be used to describe the connectivity dimensions of urban waterfront,namely the first dimension associated with ecology,the second one associated with social function,and the third one associated with context.The assessment index system and connectivity degree of urban waterfront suitable for Urban Design category were also proposed.Two typical redevelopment projects in Perth Waterfront were chosen to be the research objects.Through the comparison of connectivity degrees of urban waterfront,the two types of urban waterfront redevelopment projects which were those for the landscape restoration and for the urban development,respectively,were analyzed in functional and structural aspects.The results can provide a reference for domestic urban waterfront redevelopment project decision.
