第一批居民从哪来？他们纪念的是哪位蜀王？

Core Viewpoint - The article explores the origins and cultural evolution of the Sanxingdui civilization, highlighting the interactions between different ancient cultures in the Chengdu Plain and the significance of archaeological findings in understanding these historical developments [1][5]. Group 1: Cultural Origins - The earliest cultural traces in central Sichuan date back approximately 5,000 years, with evidence of Neolithic activities in the upper reaches of the Min River, showing similarities to the Majiayao culture in northwest China [2]. - Around 4,900 years ago, some ancient Shu people migrated from the northwest plateau to the Chengdu Plain, establishing the "Guiyuanqiao culture" and continuing dry farming practices [2][3]. - The "Baodun culture" emerged as these ancient Shu people adapted to the wetland environment of the Chengdu Plain, learning rice cultivation and building significant settlements with large city walls, influenced by cultures from the middle Yangtze River [2][3]. Group 2: Archaeological Findings - The discovery of the Baodun culture in the 1990s aligned with the late Neolithic culture of Sanxingdui, revealing that Baodun pottery was simpler yet more decorative, with rich patterns [5][6]. - Scholars have defined the first phase of Sanxingdui culture as belonging to the Baodun culture, dating from approximately 4,500 to 3,700 years ago [6]. - Recent findings, including the Guiyuanqiao site in 2009, suggest that the Sanxingdui culture may have different cultural origins, with the earliest inhabitants possibly arriving around 4,800 years ago [7]. Group 3: Cultural Integration and Development - Around 4,000 years ago, another group, possibly the Sanmiao people, migrated to the Sanxingdui site, bringing advanced bronze casting techniques and contributing to the development of the Sanxingdui civilization [8]. - The article discusses the legendary figures of the Shu kings, such as Can Cong and Yu Fu, and their connection to the Sanxingdui culture, suggesting that these figures may represent the early rulers of the region [10][11]. - The transition from the "Yufu" era to the "Du Yu" era marks significant cultural shifts, with the decline of certain artifacts indicating the end of one cultural phase and the rise of another [14].
