本文即根据他在北京大学的讲演录音整理而成。他介绍了多国考古队在恰塔胡由克遗址多年的发掘收获,讨论了该遗址在大约1500年的时间里所经历的气候变化及其经济、社会、文化、艺术和象征意义。他还试图讨论该遗址与当地生活传统有着千丝万缕联系的居民生活方式长期以来变化缓慢的原因。结果发现,一个最初具有变革和创造力的社区却越来越不愿随着周围事物的变化而变化。 This article is based on his speech recording at Peking University. He introduced the multi-national archeology team’s many years of harvesting at the Chattahohu site, discussing the climate change and its economic, social, cultural, artistic and symbolic significance that the site experienced over a period of about 1500 years. He also attempted to discuss why the lifestyle of the inhabitants of the site, inextricably linked with the tradition of local life, has been slowly changing. It turned out that a community that was initially transformed and creative was increasingly reluctant to change as things around it changed.
