A Study Of Net Pendants In The Pre-Qin Period In Northeast China

In the thesis,the fishnet sinkers of the pre-Qin period excavated in Northeast China are researched.The division of history into period,the classification of the fishnet sinkers,and the other related problems are studied.The main points are as follows:1.Through the integration of the types of fishnet sinkers of the pre-Qin period excavated in Northeast China,we can divided them into four categories: A,B,C and D.These four categories are further divided into several types and subtypes.2.According to the appearance and popularity of fishnet sinkers,they are divided into three stages.The first stage,about BC6000-BC2070,only category A and B fishnet sinkers are popular.In the second stage,about BC2070-BC1046,the period of the Xia-Shang Dynasty,the category C and D sinkers began to appear.In the third period,about BC1046-BC221,during the period from the Western Zhou Dynasty to the Warring States Period,category C gradually became popular,category A and B gradually continue to exist,and category D disappeared.3.The thesis also discusses the partition of fishnet sinkers.Northeast China can be divided into two areas:the north basin and the south basin.In the first stage,category A sinkers are mainly distributed in the north,and category B sinkers are mainly distributed in the south.In the second stage,category A is mainly distributed in north basin,and categoryB,C and D are mainly distributed in south basin.In the third stage,category A and C are mainly distributed in north basin,and category B and D are mainly distributed in south basin.4.Under the analysis above,the time changes of the distribution of fishnet sinkers are investigated.The first stage of category A fish sinker mainly distributes in east of Northeast China.The stage of category A fish sinker expend southward to Northeast China,and the third stage expands westward to Western Liaoning Province.As a whole,category A sinkers are the most widely distributed and expanding,covering almost the whole Northeast China.It can be seen that category A sinkers are the most popular.The first stage of category B sinkers mainly distributes in Southeastern Liaoning and Western Liaoning,and the second and third stages continue to extend northward.The second stage of category C sinkers appeared only in western Liaoning,and the third stage began to expand and the categories increased suddenly.The increase categories were dispersed and gradually expanded southward.Category D sinkers also appeared in the second stage,only in southeastern of south basin.
