摘　　要：特有植物的研究对于植物区系的历史发展和现状具有重要意义。以县域为单位,调查了山东省中国特有种子植物种类、区系性质及其空间分布格局。结果表明,山东省共有中国特有种子植物226种,隶属于59科143属;按生活型进行划分,有木本植物52属98种,草本植物91属128种;按分布区类型划分,可分为14个分布型;从空间分布来看,中国特有种子植物在120个县域单元中的种类数介于10~153之间,呈现出鲁中南山地和胶东丘陵区特有物种丰富多样,鲁西北平原区特有物种种类单调贫乏的特征。The study of endemic plants has great significance to the historical development and status of flora.The paper investigated the species of Chinese seed plants,properties of area,and its spatial distribution in Shandong.The results showed that,there are 226 species of endemic seed plants of China,belonging to 59 families 143 genera in Shandong province.By lifestyle,there are 98 species of woody plants belonging to 52 genera,128 species of herbs belonging to 91 genera.By distribution type,there are 14 distribution types.From the spatial distribution,the number of species of endemic seed plants of China in 120 counties ranges from 10 to 153.It presented a rich diversity of endemic species in the mountains of Central-south of Shandong province and the hilly region of Shandong peninsula,northwest Shandong plain species monotonous.
