Even though urban land-use change simulations provide useful information for decision makers, planning is generally weakly integrated into land-change modelling. However, the increasingly digitally available zoning data from statutory planning offers new opportunities. This study aims to reveal the potential effectiveness of statutory planning in terms of sustainable urban development by integrating zoning regulations in a multi-scenario simulation. Specifically, the gross floor area that can be built per parcel, as defined in the zoning plan, supports the allocation of varying degrees of urban densities. Using the CLUmondo modelling framework that couples cellular automata and multivariate logistic regression, we simulated urban growth in Madrid, Barcelona, Valencia, and Zaragoza Spanish Functional Urban Areas from 2012 to 2030 in four scenarios. The scenarios reflect the degree of planning intervention, ranging from high intervention to unrestricted development, while consider Spanish legislation and urban agenda 2030 sustainability goals. Simulations shows that by shifting growth to zones with urbanization projects almost 4200 ha of grassland and cropland could be saved from overbuilding, and 3800 ha by shifting it to zones without urbanization project. The simulation results provide critical information to support decision-makers and planners in revising plans and designing new plans to achieve sustainable urban development.

分区计划对城市土地利用变化的影响:支持城市可持续发展的多情景模拟

尽管城市土地利用变化模拟为决策者提供了有用的信息,但规划通常很少与土地变化模型集成。但是,法定规划中越来越多的数字化分区数据提供了新的机会。这项研究旨在通过将分区规章纳入多情景模拟中,揭示法定规划在可持续城市发展方面的潜在有效性。具体来说,按分区计划中的定义,每个宗地可以建造的总建筑面积支持不同程度的城市密度分配。使用结合细胞自动机和多元logistic回归的CLUmondo建模框架,我们在四种情况下模拟了2012年至2030年马德里,巴塞罗那,巴伦西亚和西班牙萨拉戈萨功能性城市地区的城市增长。这些情景反映了计划干预的程度,从高干预到无限制发展,同时考虑了西班牙立法和2030年城市议程的可持续性目标。模拟显示,通过将增长转移到具有城市化项目的区域,可以从过度建设中节省近4200公顷的草地和耕地,而将其转移到没有城市化项目的区域可以节省3800公顷。模拟结果提供了关键信息,以支持决策者和规划者修改计划和设计新计划,以实现可持续的城市发展。模拟显示,通过将增长转移到具有城市化项目的区域,可以从过度建设中节省近4200公顷的草地和耕地,而通过将其转移到没有城市化项目的区域可以节省3800公顷。模拟结果提供了关键信息,以支持决策者和规划者修改计划和设计新计划,以实现可持续的城市发展。模拟显示,通过将增长转移到具有城市化项目的区域,可以从过度建设中节省近4200公顷的草地和耕地,而将其转移到没有城市化项目的区域可以节省3800公顷。模拟结果提供了关键信息,以支持决策者和规划者修改计划和设计新计划,以实现可持续的城市发展。
