摘　　要：浙江省分布的壳斗科Fagaceae植物共6属48种(含种下分类群),以常绿植物为主,占62.5%,其中栎属Quercus为最大属(16种),水青冈属Fagus(4种)为浙江省壳斗科的表征属。将浙江省壳斗科植物分为3个类型,13个亚型,其中对中国特有种采用分布区图重叠法将其分为11个亚型。与其他省区相比,浙江与安徽的相似性系数最高(0.790 1),其次为福建,山东最低(0.222 2)。浙江省壳斗科植物区系主要是热带性质并兼有一定的温带成分,浙江成为温带和热带地理成分的植物南北延伸的过渡带。浙江省壳斗科中国特有种集中分布于西南高原地区的有29种,占82.9%,另外天目山-黄山地区(2种)、秦巴山区(4种),说明浙江壳斗科植物集中分布区具有多样性丰富,又较集中的特点。栲属Castanopsis,柯属Lithocarpus,青冈属Cyclobalanopsis和栎属存在明显的水平替代现象,其中青冈属存在一定程度的垂直替代现象。A comparative study of Fagaceae flora in China was conducted.Six genera and 48 species（including varieties） of Fagaceae flora were found in Zhejiang Province,China of which evergreen trees comprised the most with 62.5％.Meanwhile,the genera having the most species was Quercus （16） with Fagus （4 species）being typical of the other genera.In this study all Fagaceae plants were divided into three types and 13 subtypes with the species endemic to China being divided into 11 subtypes.Zhejiang,compared to other areas,had the highest similarity coefficient with Anhui Province,followed by Fujian Province; Shandong Province had the lowest.Floristic components showed tropical zone characteristics and some from the temperate zone,so the flora expressed transitional characteristics.Analysis by Fagaceae location showed three areas：the Southwest Plateau area （29 species）,the Mt.Tianmu and Mt.Huangshan area （2 species）,and the Qinling-Bashan mountainous region （4 species）.Many substitute phenomena were also found in Castanopsis,Lithocarpus,Cyclobalanopsis,and Quercus in horizon; whereas,only Cyclobalanopsis had a substitute phenomenon in the vertical.Overall,this study showed that Fagaceae in Zhejiang had rich diversity and centralization.
