摘　　要：来自苏州草鞋山遗址年代学、生物地层学和沉积学的分析结果表明，本区新石器文化演进与全新世气候突变的事件有关。高分辨率、连续的孢粉、粒度和磁化率记录证实，崧泽文化是在暖湿气候条件下出现和繁荣的，发生在５３６５ａ Ｂ．Ｐ．左右的一次干旱事件使之走向衰落，而出现在全新世大西洋期与亚北方期过渡阶段的一次气候转型事件中断了本区文明达２００ 年之久。５１６０ａ Ｂ．Ｐ．以后，气候转为暖干，经历了一次干旱事件后，良渚文化发展起来。The Eastern Plain of Taihu Lake, located at west part of the Changjiang River Delta, could cater us exceptional information both about Holocene climate changes and human activity. Most of the Neolithic culture sites in the area could be successful to serve as the proxy profiles that contain both evidence for Holocene climatic variation and vestige of human settlement. Among them, Caoxieshan cultural site, 120°45′E, 31°22′N, is most typical and could enact as a unique paradigm. High resolution and continual records of pollen, grain size and magnetic susceptibility that span 5620 years from Caoxieshan cultural site, Suzhou provide a climatic context for Neolithic culture history. The origin and flourishing of Songze cultures overlapped the Holocene Hypsithermal Interval. Prior to 5365 a B.P., the climates were sustainably humid and warm, nevertheless, at the end of Songze cultures, a serious arid event centered at about 5?365 a B.P. rendered the civilization degenerate. Ultimately, a harsh cold wet event during the transition from the warm humid Atlantic Phase to the warm dry Subboreal Phase uppered the lake level of Yangcheng lake group significantly, made the Songze cultures vanish and left a 200 year regional hiatus of human occupation. After 5?160 a B.P., climates conversed as dry and warm, the lake retreated, Liangzhu cultures, a relatively well developed civilization emerged.
