城市形态发生简单模型的比较

A comparison of simple models for urban morphogenesis

Juste Raimbault

摘要:

城市地区内人口和活动的空间分布,或中观尺度的城市形态,是多重对抗过程的结果。我们建议在本文中基准不同的城市形态发生模型,系统地比较他们可以产生的城市形式。包括不同类型的方法,如反应扩散模型,基于重力的模型和相关渗流。应用多样性搜索算法,我们在城市形态指标空间内估计每个模型的可行空间,并与全球城市地区的经验值进行比较。我们发现不同类型的过程的互补性,倡导多元化的城市模式。

英文摘要:

The spatial distribution of population and activities within urban areas, or urban form at the mesoscopic scale, is the outcome of multiple antagonist processes. We propose in this paper to benchmark different models of urban morphogenesis, to systematically compare the urban forms they can produce. Different types of approaches are included, such as a reaction-diffusion model, a gravity-based model, and correlated percolation. Applying a diversity search algorithm, we estimate the feasible space of each model within a space of urban form indicators, in comparison of empirical values for worldwide urban areas. We find a complementarity of the different types of processes, advocating for a plurality of urban models.
