【摘要】 对三星堆文明的突然消亡,至今没有令人信服的解释,而岷江支流雁门沟,沱江支流湔江及其上游支流白水河的特殊河流地貌,尚未引起人们的重视。实地考察雁门沟、白水河及湔江,通过其河流地貌特征推断白水河和湔江为断头河,雁门沟为反向河;再利用3S技术,找到了光光山一带大规模滑坡遗迹,从而判定岷江曾在今汶川雁门向东南流,穿越光光山,沿今白水河、湔江流向沱江。岷江及其支流杂谷脑河、雁门沟、文政沟的纵剖面特征,也反映出河流曾发生过大的变迁。结合三星堆、金沙遗址考古资料以及历史文献的进一步论证,最终得出发生于1099B.C.的地震引起山崩、滑坡堵江,进而引起河流改道,并导致三星堆文明的消亡和金沙文明的传承,以及杜宇时代的严重水灾。更多还原

【Abstract】 No convi1ncing explanations has been figured out on the sudden extinction of Sanxingdui Civilization currently,while insufficient attention has been paid to the special geomorphologic characters of Yanmen Ravine (a tributary of Minjiang River),Jianjiang River and Baishui River (a tributary of Jianjiang River).According to the field investigations conducted in Yanmen Ravine,Baishui River and Jianjiang River,it proves that Baishui River and Jianjiang River are beheaded rivers and Yanmen Ravine is a reversed river.Applying 3S technology,relic of massive landslide was found.All the demonstrations above prove that Minjiang River once flowed southeast in Yanmen at Wenchuan County into Tuojiang River through Mount Guangguang along Baishui River and Jianjiang River.The profiles of Minjing River,Zagunao River,Yanmen Ravine and Wenzheng Ravine also demonstrate that avulsion once happened.In line with historic record and archaeological materials,it is concluded that great earthquake in 1099 B.C.triggered landslide,Minjiang River was dammed and avulsion happened.The avulsion resulted in the subsequent extinction of the Sanxingdui Civilization and the heritage of Jinsha Civilization;as well as the serious floods in Duyu Kingdom Periods.更多还原
