首先,要了解城市如何运行,关键在于分析它如何为居住者提供公共服务。在我们的城市中,公共设施是由政府、公共或私人组织提供的公共空间,用于举办各种各样的公众活动同时也赋予城市生活的意义和价值。城市的定义及特点是具有物理和功能的双重结构。地理环境和城市形态对城市特征的贡献不亚于居民的空间分布、财富分配、公共活动场所的位置、人流和信息流以及其他城市功能结构此处毋庸赘述。物理和功能结构的数量和互动则形成了城市特征使之与众不同。 First, the key to understanding how cities operate is how to analyze how it provides public services to occupants. In our cities, public facilities are public spaces provided by government, public or private organizations for organizing various public events while also giving meaning and value to urban life. The definition and characteristics of the city is a dual structure with physical and functional. The contribution of geographical environment and urban form to urban characteristics is no less than the spatial distribution of residents, the distribution of wealth, the location of public activity places, the flow of people and information, and other urban functional structures. The number and interaction of physical and functional structures create the distinctive urban character.
