中-晚全新世姚江河谷平原古文化遗址分布变化及动因的GIS分析
GIS analysis on the distribution and causes of ancient cultural sites in the middle to late Holocene Yaojiang River valley plain
摘要
Abstract
As the birthplace of Hemudu Culture,the Yaojiang Valley has a long history of civilization evolution.During Holocene,a dramatic environmental evolution took place in this area,making it an ideal sample for studying how humans adapt to environmental changes.In this study,we collect 63 archaeological sites of Neolithic Age and Shang-Zhou dynasties,together with their information such as geographical position,cultural periodization,size,cultural layer thickness,archeological relics and remains.ArcGIS software was used to analysis their inheritance,distance from mountains,nuclear density and scale.The results are as follows.First,during the first and second phases of Hemudu culture,the number of sites was small and the inheritance was high,with an overlapping coefficient of 0.83.The number of sites increased significantly in the third and fourth phases of Hemudu culture while the inheritance reduced relatively with an overlapping coefficient of 0.73.During Liangzhu Culture and Shang-Zhou dynasties,the number and inheritance of sites both showed a downward trend.The overlapping coefficient dropped to 0.43.This shows that significant changes in the environment and population composition occurred from the third to the fourth phase of Hemudu culture,the fourth phase of Hemudu culture to Liangzhu culture,and Liangzhu culture to Shang-Zhou dynasties.Secondly,in terms of spatial distribution,archeological sites first appeared in the middle of the Yaojiang Valley and spread to the east and west in the second and fourth phase of Hemudu culture successively until they occupied the whole valley.These archeological sites were generally not more than 1500 m away from the mountains,and only showed a trend of spreading to the plain in the fourth phase of the Hemudu culture and Shang-Zhou dynasties,suggesting that the Yaojiang River was relatively rich in land resources during these two periods,which may be caused by large-scale regression.Thirdly,From the first phase of Hemudu culture to Shang-Zhou dynasties,the Yaojiang Valley was filled from remnant ancient bay into coastal plain.During this period,the formation and the diversion of Yaojiang River,as well as the topographic inversion of coastal area and plain hinterland also happened in this area.关键词
