摘　　要：晚更新世-早全新世是东亚地区人类社会发展过程中的重要阶段。深受气候变化影响的植被与早期人类赖以生存的食物紧密相关,因此研究植被变化对于更深入理解史前人类社会具有积极的意义。广西地区的史前人类遗址数量丰富,但该时期人类与植被之间关系的研究十分有限。本研究通过对广西田东独山洞厚约150 cm的沉积剖面进行孢粉分析,并结合已发表的考古遗址数据,重建晚更新世-早全新世独山洞周边的植被变化,探讨人类活动与植被变化之间的关系。结果显示,晚更新世(约15700~14200 cal.a B.P.)独山洞剖面周边分布有常绿阔叶林以及相对开阔的草地,区域资源型植物丰富,适合狩猎采集人群生存;而在早全新世(约9500~7800 cal.a B.P.),人类活动增强,独山洞周边阔叶树减少,草本植物比例升高,植被景观变得开阔,可能反映了人类活动对植被景观的影响。The Late Pleistocene-Early Holocene is a critical period in the development of human society in East Asia.The vegetation landscape is essential for a better understanding of prehistoric societies since it was closely associated with food that early human needed to survive and is heavily impacted by climate change.Though there were numerous prehistoric archaeological sites in Guangxi,the relationship between human activities and vegetation change wasn't well understood during this period.Dushan cave(23°30′08″N,107°08′5.5″E;250 m a.s.l.)is located 10 km south of Tiandong County,Guangxi.An archaeological excavation was conducted at the entrance of the cave of Dushan cave,stone artifacts,pottery shards,animal and human bones were found in the excavation area.Four samples from surface soil(2 samples inside and 2 samples outside the cave),6 dating samples and 30 soil samples from a 150-cm section of Dushan cave were respectively collected in order to evaluate the reliability of vegetation reconstruction by pollen in cave sediments,establish age-depth model of this section and reconstruct vegetation changes around Dushan cave.In addition,14C dating results of prehistoric archaeological sites(2000~20000 a B.P.)in Guangxi were collected and applied to analyzes the relationship between human activities and vegetation changes during the Late Pleistocene-Early Holocene.Our results show that Dushan cave was mainly occupied by human in the Late Pleistocene(15700~14400 cal.a B.P.)and Early Holocene(9500~7800 cal.a B.P.).Pollen spectra from surface sediment inside Dushaan cave is similar to those outside the cave,and pollen spectra within Dushan cave can reliably reconstruct vegetation.Evergreen broad-leaved forest and grassland were scattered around Dushan cave,where large numbers of nut trees including Quercus,Cyclobalanopsis and Castanea/Castanopsis provided ample food for hunters and gatherers during the period of 15700~14400 cal.a B.P.While there was an open vegetation landscape characterized by a significant decr
