The process was later accelerated due to the introduction of city planning by German colonizers. The city’s planning and urban construction was changed many times in early modern times, dominated by different administrative bodies and proceeding independently from other cities. After 58 years of planning and construction from 1891 to 1949, Qingdao has developed into a large city with integral style and seaport features. Based on an abundance of historical materials, this paper discusses the three major historical stages and seven development phases of Qingdao’s urban planning in the early modern times, as well as the planning content and characteristics of each stage.展开更多
