摘要

Integrating a diverse set of land use types within a neighborhood is a central tenet of smart growth policy. Over a generation of urban planning research has heralded the transportation, land use, and public health benefits arising from a balanced supply of local land uses, including the improved feasibility for pedestrian travel. However, land use mixing has largely remained a transportation-land use planning goal without a conceptually valid set of environmental indicators quantifying this multifaceted spatial phenomenon. In this study, we incorporated activity-based transportation planning and landscape ecology theory within a confirmatory factor analysis framework to introduce a land use mix construct indicative of the paired landscape pattern aspects of composition and configuration. We found that our activity-related land use mix measure, and not the commonly adopted entropy-based index, predicted walk mode choice and home-based walk trip frequency when operationalized at three geographic scales. 在街区内整合多种用地类型是理性增长政策的核心原则。超过一代人的城市规划研究已经证明了交通、用地和公共卫生的好处都来自当地用地的平衡供应，包括行人出行可行性的改善。然而，土地利用的混合在很大程度上依然是交通-用地的一个规划目标，而没有一套在观念上有效的环境指标来量化这种多方面的空间现象。在此项研究中，我们将基于活动的交通规划和景观生态学理论结合在一个验证性因子的分析框架中，引入了一个用地混合结构，表明了成分和配置的对应景观形态方面。我们发现，我们所用的基于活动的用地混合指标，而不是通常采用的基于熵的指数，在三个地理尺度下运行时，能够预测了步行模式的选择和基于家庭的步行出行频率。
