摘要

关于城市土地利用可能演变的描述性情景是城市规划的重要工具。尽管这些情景模拟具有巨大的潜力,但还需要进一步的特征描述,以便能够对其进行评估和比较,从而为公共政策提供更有效的支持。空间移动窗口指标是评估这些情景的最常用工具之一,它是一种有用的机制,可从模拟土地利用地图中提取有关城市多样性和城市增长模式的准确信息。本文试图进一步探讨这一问题,主要有两个目的。首先,开发并实施 vSHEI 和 vLEI 这两个多尺度组成和配置矢量移动窗口指标,用于计算城市多样性和城市增长模式。其次,通过对埃纳雷斯走廊(西班牙)的三个前景方案进行空间显式模拟来测试这些指标,比较结果并分析方案叙述与其空间配置的匹配程度,正如 vSHEI 和 vLEI 所衡量的那样。通过实施 vSHEI 和 vLEI,我们获得了地方层面的城市多样性和城市扩张值,与栅格度量或矢量 Patch-Matrix 模型度量相比,这些度量提供了更精确、更真实、可映射的城市土地利用组成和配置信息。我们还使用这些指标来测试模拟场景是否与叙述性故事情节中的描述相符。我们的结果表明,矢量移动窗口度量法具有在地块层面描述不同情景下可能形成的城市格局的潜力。

Adapting moving-window metrics to vector datasets for the characterization and comparison of simulated urban scenarios
Descriptive scenarios about the possible evolution of land use in our cities are essential instruments in urban planning. Although the simulation of these scenarios has enormous potential, further characterization is needed in order to be able to evaluate and compare them so as to provide more effective support for public policy. One of the most commonly used tools for assessing these scenarios is spatial moving-window metrics, a useful mechanism for extracting accurate information from simulated land-use maps on urban diversity and urban growth patterns. This article seeks to explore this question further and has two main aims. First, to develop and implement vSHEI and vLEI, two multiscale composition and configuration vector moving-window metrics for calculating urban diversity and urban growth patterns. Second, to test these metrics using the spatially explicit simulation of three prospective scenarios in the Henares Corridor (Spain), comparing the results and analyzing how well the scenario narratives match their spatial configuration, as measured using vSHEI and vLEI. Via the implementation of vSHEI and vLEI, we obtained urban diversity and urban expansion values at a local level, offering more precise and more realistic, mappable information on the composition and configuration of urban land use than that provided by raster metrics or by vector Patch-Matrix model metrics. We also used these metrics to test whether the simulated scenarios matched their description in the narrative storylines. Our results demonstrate the potential of vector moving-window metrics for characterizing the urban patterns that might develop under different scenarios at the parcel level.
