中文摘要：

通过野外实地考察和标本资料的鉴定表明：新疆西昆仑山菊苣族植物共有9属41种1变种,占该区菊科植物属、种总数的29.03%和30.83%,为其第二大族,发现本区系新记录植物5种。该区菊苣族植物中单种属（3属）和寡种属（5属）共计8属,所占比例较高,但在种级水平多种属（蒲公英属Taraxacum 1属含17种）和寡种属（5属21种）共计6属38种,占总种数的92.68%,优势明显。本区系新疆西昆仑山特有种有3种,中国西昆仑山仅分布种有2种,显示有一定特有现象。植物生活型以多年生草本（地面芽）植物为主,有38种,占92.68%,另为一年生植物。该区系的地理成分可划分为7个分布区类型,其中温带及含温带分布的属有6属,占总属数的66.67%,温带性质比较明显。本区与相邻的中国帕米尔高原和中国喀喇昆仑山菊苣族属的相似性系数分别高达58.33%和60.00%,表明与两地有紧密的联系。

英文摘要：

Identified by the field survey and sample data,the results revealed that there were totally 41 species and 1 variety in 9 genera of Cichorieae Spreng plants in the west Kunlun Mountain in Xinjiang,they accounted for29. 03% and 30. 83% of the genera and species respectively,and 5 new species were recorded. Among them,there were 3 monotypic genera and 5 few-species genera,they accounted the high proportions of chicory family plants. But at the species level of divers genera（ Taraxacum Wigg. has 1 genus with 17 species） and few genera（ 5 genera with21 species）,there were total 38 species in 6 genera and accounted for 92. 68% of the total species,and they have obvious advantages. The flora in west Kunlun Mountain in Xinjiang had three endemic species,but only 2 species were distributed in the west Kunlun Mountain in China,there was a certain peculiar distribution. The plant life form was dominated by perennial herbaceous plants（ ground bud）,there were 38 species and accounted for 92. 68%,and then annuals. Floristic geographical elements of the flora could be divided into seven distribution types,in which there were 6 temperate and temperate-containing genera,they accounted for 66. 67% of the total,and the temperate properties were obvious. The similarity coefficients of Cichorieae Spreng in the study area with those in the Pamir and Karakoram of China were 58. 33% and 60. 00% respectively,which revealed that the relations between the study area and the two places were close.
