城市街道空间尺度设计的城市主义思考

城市主义为城市规划设计提供了科学有效的依据和方法，尤其在全球倡导城市健康和应对气候问题的新时期，其强调的形态紧凑、功能混合、适于步行、人本尺度、公交优先和保护历史传承等核心价值，已经起到了引导城市整体可持续发展的重要作用。城市街道空间设计应采用人本尺度，有利于步行，增强市民体质健康；减少车行，降低环境和大气污染。在此背景下，本文以步行出行比例较高的英国为例，通过介绍其街道空间的三个核心要素：机动车道、公共空间及慢行系统的设计导则和指引，与我国街道空间设计若干标准进行对比分析，并提出改善建议，以期为我国适应新时期的城市规划与建设提供参考。

Thoughts of Dimension Design of City Street Space Based on Urbanism

Urbanism has provided scientific and efficient basis and methods for urban planning practice, especially in the new period of advocating urban health and dealing with climate problem all over the world. Its essential values such as compact configuration, land use mix, walkable neighborhood, people-oriented dimension, public transportation and history conservation etc. have played important guiding roles for city sustainable development. The dimension of street space should be suitable for walking, thus to improve people＇s health conditions; reduce vehicle uses thus to decrease pollutions. In this context, the paper takes the UK as an example with the highest proportion of non-motor trips in Europe, to introduce three core elements of street design： carriageway, public realm and walking ＆ cycling, and compares with China in corresponding contents; finally, the paper proposes suggestions for improving streets design in China.
