摘　　要：环境与古文化的关系是许多学科共同关注的研究课题。我国环境考古学的研究表明，对新石器时代文化与古气候、古环境的讨论，大大受制于对古气候定量化和高分辨率的研究。近年来，自然科学的研究方法（孢粉、大植物化石和植物硅酸体分析、动物生态分析、土壤微形态分析等）在考古工作中得到越来越广泛的应用，但是，进行多替代性指标和定量的环境恢复工作还很少见。因此，本文在前人研究的基础上，对西安半坡遗址进行孢粉、Quantitative reconstruction of palaeoclimate and palaeoenvironment for the Neolithic archaeology sites in China are less reported. In this paper, we try to apply pollen analysis and carbon isotope measurement of the organic matter from the culture deposit and field observations and archaeology investigations to tentatively quantitative reconstruct palaeoprecipitation and palaeovegetation for the Banpo Neolithic site, Xi＇an, China. The results show that the annual mean precipitation is around 600mm during the late Banpo＇s culture period （5740-5930 a B. P. ）, and the human culture declined as the climate became graduatedly cold and dry. The climate changes have significantly influenced development of the human civilization.
