摘　　要：通过对金佛山山顶以药池坝为中心的5个不同植被类型的表土样品的孢粉分析,研究了该区表土孢粉组合特征及其与现代植被类型的关系.结果显示:研究区孢粉组合以马尾松(Pinus massonianaLamb)、银杉(CathayaargyrophyllaChun et Kuang.)、流苏树(Chiananthus retususLindl.)、峨眉栲(Castanopsis plautycathaHayata.)、珍珠栗(Castanea henryiRehd.et Wils.)、银叶杜茎山(Maesa argenteaA.DC.)、山枇杷(Zanthoxylum dissitumHemsl.)、十大功劳(Mahonia japonicaDC.)、大楼梯草(Elatostema umbellatumBl.)、清明草(Gnaphalium multi-cepsWall.)、什科洛费里蕨(Phyllitis scolopendriumNewmann.)、肾蕨(Nephrolepis cordifoliaPresl.)、粗糙鳞蕨(Microlepia hirtaPr.)和介蕨(Dryoahyrium boryanumChing.)等为主,这与该区域内的实际植被情况大致相同.运用LuoPacias孢粉鉴定系统将孢粉鉴定到种,共225种,为今后在这一地区开展第四纪古植被、古气候和古环境等研究提供参考性据.Spore pollen analysis was made of the surface soil samples collected from 5 locations with different vegetation types around the Yaochi Dam on the top of Mt. Jinfo to study the characteristics of the spore-pollen assemblages and their relationship with the modern vegetation types. The results showed that dominant spore pollen assemblages in the region were to Pinus massoniana Lamb. , Cathaya argyrophylla Chun et Kuang. , Chiananthus retusus Lindl. , Castanopsisplautycatha Hayata, Castanea henryi Rehd. et Wils, Mahoniajaponica DC. , Elatosterna urnbellaturn B1. , Gnaphalium multiceps Wall. , Dryoahyrium boryanurnChing. , Nephrolepis cordifolia Presl. , Microlepia hirta Pr. and Phyllitis scolopendrium Newmann. , a result which is consistent with the actual vegetation in this region. The spore-pollen was identified with the I.uoPacias identification system, and a total of 225 species were identified. These results will provide useful information for the study of Quaternary paleovegetation, paleoclimate and palaeoenvironment in this region.
