Abstract: The changes of Mid-Holocene paleoclimate-paleoenvironment along the eastern coast of Zhejiang province and its influence on the Hemudu Ancients are discussed in this paper. Results of the study indicate that the coming of Mid-Holocene megathermal maximum is an important factor for the domicile and the development of the Hemudu Ancients, and it is an favorable condition for the development of Hemudu oryzo-agriculture at that time. The divided periods of the paleoclimatic-paleoenvironmental changes in Zhejiang Province can be well correlated with the periods of the development of the Hemudu Ancients. The tropical climatic-environmental changes, including the aggravation of natural calamities caused by these changes, have great influence on the changes of the life of the Hemudu Ancients. Especially the process of the paleoclimatic-paleoenvironmental changes from slow cooling turning to rapid warming is probably one of the essential causes for the great change of the life of the Hemudu Ancients.
