摘要

The East China coastal plain is one of the most important Neolithic culture areas in China,where rich archaeological sites including those producing the earliest domesticated rice are observed.It is also a place where landscape has experienced dramatic evolution during the Holocene when both sea level and climate changed,such that it is an ideal place for studying human-environment interaction.This study investigated over 2000 sites of pre-history and Shang and Zhou Dynasties,with 655 of which being Neolithic ages,by using DEM and GIS methods.The results suggest that the spatial and temporal distribution of Neolithic sites has largely been controlled by landscape evolution (particularly changes in coastal line),which ultimately governed by sea level changes.During early Holocene,Neolithic sites sparsely distributed in the intermountain basins of east Zhejiang Province,far from the influence of ocean.Over the period of 9-7 ka,the coastal plain (including the shelf) was largely submerged,only the feet of low hills to the south and southwest of the study area,and islands protruding the estuary,cradled limited nnmber of settlements with characteristic "maritime components".At about 7 ka,sea level rise decelerated prominently,while sediments supply in the drainage remained high value,the combination of which led to land formation and propagation.Vast space during this period facilitated the growth of settlements in both size and number.In the mean time,however,the coastal plain was vulnerable to extreme environmental events such as storms and flooding owning to its geomorphic nature,which exerted great influence on the rise and fall of Neolithic culture.
