摘要： 结合标本及实地考察,对喀喇昆仑山龙胆科植物进行形态分类学研究。结果表明:该区龙胆科植物有6属19种1变种,其中本区新记录种1种:铺散肋柱花Lomatogonium thomsonii;新疆新记录种3种:短蕊龙胆Gentiana ludlowii、圆齿褶龙胆Gentiana crenulato-truncata、华北獐牙菜Swertia wolfangiana。本区龙胆科多种属仅龙胆属Gentiana 1属7种,寡种属有5属12种;与中国帕米尔高原龙胆科植物联系最紧密,属、种相似性系数分别达到 85.7%和53.3%;其次与阿富汗和青藏高原联系比较紧密,其属、种相似性系数分别为42.9%,6.1%和37.5%,7.2%,而与东喜马拉雅联系较少,相似性系数仅为14.3%,且无共有种。本区龙胆科植物地理成分以北温带分布区类型为主,占总属数和总种数的83.3%和63.2%,区系温带性质明显;生活型以一年生植物为主,有5属17种,占总种数的89.5%,地面芽植物仅1属2种,占总种数的10.5%。

Abstract: In this paper, the classification and distribution of Gentianaceae are researched based on the data of field investigation and specimens. The results show that 19 species and 1 variety in 6 genera of Gentianaceae are recorded in the Karakorum Mountains in China, among them there is 1 newly recorded species of Karakorum Mountains in China, it is Lomatogonium thomsonii, there are 3 newly recorded species of Xinjiang in China, and they are Gentiana ludlowii, Gentiana crenulato-truncata and Swertia wolfangiana. There are 7 species in 1 polytypic genus of Gentianaceae and 12 species in 5 monotypic genera in the Karakorum Mountains in China; the relations of flora in this area are the closest with those in the Pamirs of China, the similarity coefficients of genera and species are 85.7% and 53.3% respectively; secondly, the relations of flora in this area are close with those in Afghanistan and the Qinghai-Tibetan Plateau, the similarity coefficients of genera and species are 42.9% and 6.1%, 37.5% and 7.2%, respectively. The distribution-type of genera in Gentianaceae is temperate nature in this area. The 89.5% species of Gentianaceae in this area are therophytes which contain 17 species in 5 genera, and therefore they are the dominating components in the plant life form spectrum in this area, and 10.5% species of Gentianaceae in this area are Hemicryptophytes which contain 2 species in 1 genus.
