Twenty-eight sporo-pollen samples from the ABYT2008and ABYT2009at Yuhuicun site were analyzed.The results show that before the Longshan culture period which from 4.5to 4.0kaBP,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 000aBP 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.
