中国考古学史上自王城岗城址发现并确认以来,史前及夏商阶段的早期城址不断从田野工作中涌现出来,给我们研究中国古代文明起源和城市化进程提供了丰富的资料,经过前辈学者的梳理,我们发现在史前及夏商时期我国不同地区的早期城市在筑城模式、出现原因等几个方面均表现出不同之处,我们认为早期城市存在三种城市发展类型。 Since the discovery and confirmation of the site of Wangchenggang in the history of Chinese archeology, the early urban sites of prehistoric and Xia Shang stages have emerged from fieldwork continuously, providing us with rich information on the origins of ancient Chinese civilization and the process of urbanization. In the prehistoric and Xia and Shang dynasties, we find that the early cities in different regions of China showed differences in the mode of fortification and the reasons for their occurrence. We think there are three types of urban development in the early cities.
