一种检测和设计城市环境中活力结构的新方法

A New Approach to Detecting and Designing Living Structure of Urban Environments

可持续城市设计和城市规划并不是一种类似于乐高玩具的预制构件的组合,而是像胚胎一样朝着一个完整体不断演进和适应的生长过程。这种完整体具有被称为“活力结构”的突出特征,它是由很多小的次级结构、较少大的次级结构组成。为了对其进行检测,本文提出了一种揭示城市环境中潜在活力结构的新方法。这种方法将城市环境视为一个整体,并采用递归方法将其分解为从大到小不同尺度等级的、有意义的次级整体。这种方法不仅能帮助我们更好地理解作为一个活力结构的城市环境本身,同时能帮助我们更好地规划或改造城市规划,使其更加具有活力,变得更加美丽。

Sustainable urban design or planning is not a LEGO-like assembly of prefabricated elements,but an embryo-like growth with persistent differentiation and adaptation towards a coherent whole.The coherent whole has a striking character–called living structure–that consists of far more small substructures than large ones.To detect the living structure,this paper develops a new approach for uncovering the underlying living structure of urban environments.The approach takes an urban environment as a whole and recursively decomposes it into meaningful subwholes at different levels of hierarchy or scale ranging from the largest to the smallest.This approach helps us not only better understand an urban environment as a living structure,but also better plan or transform the urban environment to be living or more living,or equivalently to be beautiful or more beautiful.
