论文摘要
城市地区人口和活动的空间分布是多个对手过程的结果。我们在本文中提出建议，以基于不同的城市形态发生模型，以系统地比较它们可以产生的城市形式。包括不同类型的方法，例如反应扩散模型，基于重力的模型和相关的渗透。采用多样性搜索算法，我们估计了城市形式指标空间中每个模型的可行空间，并比较全球城市地区的经验价值。我们发现不同类型的过程的互补性，提倡多个城市模型。
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.
