摘要
我国街区制与西班牙巴塞罗那超级街区是近年被热议的两种街区改革方向。首先,从概念辨析、历史梳理、规划方式三个方面进行对比,发现:两种改革都以可持续的城市生活为终极目标,并且在策略上并非相反而是互补。进一步比较两种改革的评价体系,具体通过路网密度、道路健康、交通效率三个指标诠释如何“以人为本”地重塑街道的生活功能。最后,针对我国街区改革中易被忽视的差异性和层次性,提出两个关键点:(1)街区应依差异需求确定空间尺度,弱化绝对的大小、开闭和疏密概念;(2)街区应按功能结构建立层次体系,避免形成均质化、碎片化的城市结构。结合技术发展趋势预测未来规划方向,为我国街区改革和“未来社区”建设提供新的思路。
City block in China and Superilles(Superblock)in Barcelona,Spain are two reform directions that have been debated heatedly in recent years.Firstly,comparative research is carried out from three aspects:conceptual analysis,historical review,and planning methods.It is found that both reforms take sustainable urban life as the ultimate goal,and their strategies are not opposite but complementary.Secondly,through a further comparison on the evaluation systems of the two reforms,specifically through the three indicators of road network density,road health,and traffic efficiency,the paper explains how to reshape the life function of the street with a“people-oriented”approach.Finally,in view of differences and hierarchy that are easily overlooked in China’s block reform,two key points are proposed:(1)the spatial scale of blocks should be designed in line with different needs,which should weaken the concepts such as absolute large or small,opening or closing,and sparse or dense;(2)a hierarchical system should be established in blocks according to the functional structure,which should avoid the formation of a homogeneous and fragmented urban structure.This paper predicts the direction of future planning from the perspective of technological development trends,which will provide new ideas for the reform of blocks and the construction of“future communities”in China.
