美国的城市史是一部发展和变化的历史。自从在东海岸建立起一些小城市之后,南部、北部、西部,以及最后西海岸地区的城市就逐步发展起来。这个城市网络一旦建立,这些城市的内部发展便成为美国城市风貌的主要特色。到了二十世纪初,美国向城市发展的这个倾势开始加快。 American urban history is a history of development and change. Since the establishment of small cities on the east coast, cities in the southern, northern, western, and finally West Coast regions have evolved. Once the city network is established, the internal development of these cities has become a major feature of the American cityscape. By the early twentieth century, the United States began to accelerate its development toward cities.
