试论跨湖桥文化的来源和对外影响——兼论新石器时代中期长江中下游地区间的文化交流

On the Source and the External Influence of the Kuahuqiao Culture:Also on the Cultural Exchanges Between the Middle and Lower Reaches of the Yangtze River in the Middle of Neolithic Age

公元前7000年末期,长江下游在上山文化基础上接受长江中游彭头山文化的影响发展成跨湖桥文化;公元前6000年初期,处于兴盛期的跨湖桥文化又反向影响长江中游,促成彭头山文化向皂市下层文化的转变。通过交流融合,此后长江中下游地区文化大同小异,总体构成一个新的以釜、圈足盘、豆为主要特征的文化系统,或可称之为"长江中下游文化系统"。

In the end of 7000 years BC,based on the Shangshan Culture and influenced by the Pengtoushan Culture in the middle reaches of the Yangtze River,the native culture in the lower reaches of the Yangtze River developed to be the Kuahuqiao Culture which made a reverse impact on the culture in the middle reaches of the Yangtze River in its flourish period at the beginning of 6 000 years BC,and facilitated the Pengtoushan Culture changing into the Lower Zaoshi Culture.Through the exchange and integration,cultures in the middle and lower reaches of the Yangtze River became almost similar and then constituted a new cultural system characterized by kettle,circular-footed tray and Dou（豆）,which can also be called as＂Cultural system of the middle and lower reaches of the Yangtze River＂.
