摘　　要：结合标本和实地考察,对中国喀喇昆仑山地区玄参科植物进行形态分类学研究。结果表明,该区域玄参科植物有6属19种,其中2种为新记录种,分别为齿叶玄参(Scrophularia dentata)、长距柳穿鱼(Linar-ia longicalcarata)。该区玄参科植物单种属有2属;多种属和寡种属共4属17种,分别占总属数和总种数的66.7%和89.5%,在植物区系中占有明显的主导地位。喀喇昆仑山与中国帕米尔高原属、种相似性系数分别为75%、56.7%,表明两地区系联系紧密;植物区系为温带性质;植物生活型以地面芽植物为主,占总种数的73.7%。Based on wild investigating and specimens,this paper presents the classification,distribution of Scrophulariaceae.About six genera 19 species of Scrophulariaceae are recorded to occur in Karakorum Mountatins in China,Among them,there are two new recorded species of Karakorum Mountains in China,they are Scrophularia dentata and Linaria longicalcarata.There are two genera of Monotypic genera of Scrophulariaceae in Karakorum Mountatins in China.Polytypic genera and Monotypic genera which contain four genera 17 species are in ascendant of Scrophulariaceae in this area,accounting for 66.7% of total genera and 89.5% of total species.The relations of flora in this area are closer with that in the Pamirs of China,the similarity coefficient of genera and speceis is 75% and 56.7% respectively.The distributlon-type of genera in Scrophulariaceae is temperate nature in this area.The 73.7% of species of Scrophulariaceae in this area is Hemicryptophytes,and therefore it is the dominating components in the plant life form spectrum in this area.
