摘　　要：对禹会村遗址ABYT2008探方和ABYT2009探方地层采集的28个土样进行了孢粉分析,结果表明在4 500—4 000aBP的龙山文化产生之前,研究区域以禾本科为主的草本占优势,总体体现出干凉的气候特点,但在剖面底部出现环纹藻,体现阶段性湿生环境。在龙山文化时期,研究区域总体以草本占优势,同时生长着松属、落叶栎属、榆属、枫杨属、大戟科、禾本科、菊科、莎草科和葎草属等及少许蕨类,体现出温凉较干燥的气候条件,其中,龙山文化前期,孢粉浓度较大,木本含量较多,蕨类植物也较多,气候环境较温暖湿润;而龙山文化后期孢粉浓度相对较小,木本含量较少,草本含量较多,蕨类植物很少,气候条件较凉干。禹会村遗址地层忠实记录了4 500—4 000aBP植被与气候环境变化信息,响应于中国东部季风区中晚全新世转型期间由暖湿转向温凉干燥的气候环境变化特点。Twenty-eight sporo-pollen samples from the ABYT2008 and ABYT2009 at Yuhuicun site were analyzed. The results show that before the Longshan culture period which from 4.5 to 4.0 kaBP, the study area was dominated by the Poaceae herbal. It reflects a cool and dry climate conditions, but there are ringed algaes at the bottom of the section, which shows a wet environment. During the period of Longshan culture, the study area was dominated by herbaceous, together with Pinus, deciduous Quercus, Ulmus, Pterocarya, Euphorbiaceae, Gramineae, Compositae, Cyperaceae, Humulus and a little fernclass, reflecting a temperate and dry weather conditions. For the early period of the Longshan culture, pollen-spore concentration are higher, woody and ferns content are more, which indicates a warm and humid climate while during the late Longshan culture period, pollen-spore concentration is relatively lower, with less woody content, more herbal content and less ferns, which indicates dry. climatic conditions. The Yuhuicun site faithfully recorded the 4 500 4 000 aBP vegetation and environmental changes, in response to the transition from the warm-humid to the cool-dry climate characteristics in the monsoon region of East China during the late Holocene.
