摘　　要：基于野外调查,采集植物标本以及对相关文献资料进行整理,构建中天山野生种子植物名录,在此基础上对该地区野生种子植物区系进行分析。结果表明:(1)中天山地区共有野生种子植物81科453属1 567种;(2)优势科有菊科、禾本科、豆科、十字花科、唇形科、毛茛科等17科,表征科有石竹科、莎草科、百合科、茜草科、龙胆科、禾本科、蓼科等7科;(3)区系地理成分以温带分布型为主,其中科级水平上,温带分布型所属科共有36科,占到总科数(不含世界广布科)的76.60%。属级水平上,温带性质分布型的属有377属,占总属数的94.96%。同时该地区植物物种与地中海、中亚、西亚交流相对较多,与东亚交流很少。Based on the field investigation, some specimens and data of relative information, we created a cat- alog of wild seed pl.ants,and analyzed the floristic of wild seed plants. The results show that-（1） there are 1 567 species in 453 genera and 81 families of wild seed plants in the Middle Tianshan Mountains of Xin- jiang. （2） There are 17 dominan families, such as Compositae, Gramineae, Leguminosae, Cruciferae, Labia- tae, Ranunculaceae and 7 typical families, ie. Caryophyllaceae, Cyperaceae, Liliaceae, Rubiaceae, Gentianace- ae, Gramineae, Polygonaceae. （3） The floristic composition of the temperate-based, including the section lev- el,temperate-type belongs to 36 families,accounting for the total number of subjects （excluding the world wide families） of 76.60%. In a grade level,the temperate distribution patterns of the 377 genera,is the to- tal number of 94.96%. At the same time,some plant species are the most interflows between in this area and the Mediterranean, Central Asia, West Asia, little communication with East Asia. And the interflows with the East Asian flora is the lowest.
