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.

摘要： 初步讨论了浙江东部中全新世古气候古环境变化及其对河姆渡古人类发展的影响。研究结果表明，中全新世大暖期是促使河姆渡古人类定居、发展和稻作农业在本区出现发展的重要条件，古气候古环境不同变化阶段与河姆渡古人类的发展阶段可以相互对比，而当时近于热带的古气候古环境变化，包括其导致的自然灾害的加强，对河姆渡古人类的生产，生活面貌的变化和发展有深刻影响，特别是缓慢降温后紧接着急剧升温的变化过程是引起人类发展面貌发生重大改变的一个重要因素。
