成都平原夏商时期的考古学文化变迁是一个需要系统考察的课题,它涉及多方面的问题。本文从陶器这一层面进行了研究,我们分别将金沙遗址兰苑地点和三星堆文化中的小平底罐分为四型和六型,通过对这些小平底罐形制演变规律的分析,我们认为进入十二桥文化阶段,在三星堆文化和十二桥文化中均属重要器类的小平底罐已经出现了一些新的变化,器物群上的变化也与此相合。该研究提醒我们对于十二桥文化中的“三星堆文化因素”还需细致审查。对于三星堆器物坑和坑口之上地层中所出陶器以及对于金沙遗址郎家村精品房地点出土陶器的分析都表明它们已进入十二桥文化阶段了。本文还提到三星堆文化时期成都平原的遗址很少,这可能与该文化的人群大量外迁至峡江地区等地有关,而进入十二桥文化阶段,成都平原的遗址数大量增加,或许又与此时峡江地区等地的人群大量进入成都平原有关。 The Archeology Cultural Change in Xia and Shang Dynasties in Chengdu Plain is a subject that needs systematic investigation. It involves many aspects. In this paper, the pottery from this level were studied, we respectively, or the Sands site in Sanxingdui and Sanxingdui culture in the small flat-bottomed cans into four types and six types of these flat-bottomed pot shape evolution of the law, we believe that into the ten Second bridge culture stage, both in Sanxingdui culture and twelfth bridge culture are important categories of small flat-bottomed tank has been some new changes, changes in the device group also coincides with this. The study reminds us that the “Sanxingdui cultural factors” in the Twelve Bridge Culture need to be carefully examined. Analysis of the pottery from the strata in the Sanxingdui pluton and the pit and the unearthed pottery from the Jinsha site Langjacun boutique show that they have entered the Twelve Bridge Cultures. This article also mentions that there are few sites in Chengdu Plain during the Sanxingdui culture period, which may be related to the massive relocation of the cultural population to the Xiajiang River and other places. However, in the 12th Bridge cultural stage, the number of sites in the Chengdu Plain has increased greatly, At this time, people in Xiajiang River and other places entered the Chengdu Plain in large quantities.
