Chu's Forces Changes In The Western Jianghan Plain During The Eastern Zhou Dynasty

The Western Jianghan Plain is one of the most abundant area with Chu culture remains during the Eastern Zhou Dynasty,the Chu culture research in this area is a focus for academic circle,which relates to the migration of Chu's capital,Chu's forces changes in The Western Jianghan Plain are the hot topic by many scholars.This paper firstly gives an analysis on tombs within this region,and distinguish the chronological information and rank information,clear tombs' rank,structures,shape.And from this information to understand the Chu's forces changes in this area.according to the results,in the early-middle Spring and Autumn Period,The Western Jianghan Plain could just touch the edge of Chu's forces;then form the late Spring and Autumn Period to the early Warring Period,Chu's forces rapid development here,and probably at this stage of late become the core region of Chu's forces;during the middle Warring Period,Chu's forces reach to the peak;entered the late Warring Period,Chu's forees began to decline,in 278 BC.Chu gets out of this region gradually along with Qin's conquer.Further in-depth study,we can through the tombs' rank,structures,shape to establish the connection between the tombs and in the address.And through such connection,we know some tombs have no connections with Jinan City,and is closely related to Jijiahu City.So,the remains of The Western Jianghan Plain can be divided into two area,the remains' chronological in Jijiahu area is early than Jinan area,and also around the city we found Chu King's tomb.Therefore,if the capital city of Chu migrated to The Western Jianghan Plain,at the first it should be Jijiahu City,then it move to Jinan City.To sum up,at the same time of the changing of Chu's forces in the Western Jianghan Plain,society has been changing.According to the archaeological remains,during the early-middle Spring and Autumn Period,the Western Jianghan Plain's culture is influenced by the Central Plain.Then form the late Spring and Autumn Period to the early Warring Period,the typical implements and combinations appear.And enter the Warring Period,the expansion of soc ial productivity,great changes have taken place in tnmhs' struutures during the middle Warring Period.implements combinations and tombs' structures Inherited the previous,entered the late Warring Period,although implements combinations and tombs' structures have no too big change,but the number of tombs have been dramatically reduced,which suggests that population decline,class is reduced,society is falling down,finally defeated by Qin.
