摘　　要：晋西黄土高原在植物区系区划中属于泛北极植物区、中国——日本森林植物亚区、华北地区、黄土高原亚地区。全区共有维管束植物664种,分属于96科、348属。科、属、种分别为山西植物区系的56.8%、39.0%、27.9%。菊科、禾本科、蔷薇科、豆科为该区的优势科,共含236种,占总种数的35.5%。而区域性的单种科与少种科多达63科,占到全部科数的65.6%,反映了该区分类群成分的复杂性,具有强烈的北方半干旱区的特点。植物区系的分布区类型分析显示,该区系是以北温带分布为主,与热带分布和东亚分布有紧密联系。在该区系已记录的植物中,有两个新分类群,有12种珍稀濒危植物,有7种、4变种为《山西植物志》未记载的植物。该区可供开发利用的植物资源达70%之多,合理开发、利用、保护这些植物资源,对实现经济与社会的可持续发展十分必要。According to flora division,the loess plateau in the west of Shanxi Province belongs to the Holarctic flora,China-Japan forest plant subregion,north China region and loess plateau subregion.There are 664 species of vascular plants in the flora,belonging to 96 families and 348 genera.The ratios of all the families,genera and species in the Shanxi flora are 56.8%,39.0%,27.9%,respectively.And there are as many as 63 families which regional single family and less family,account for 65.6% of the whole families.This showed that reflects the composition of taxon for the flora was complicated,and the flora was the strong Semi-arid area of North of China characteristics.The analysis on flora＇s areal-types show that,the main areal-types of this flora was North Temperate,close connection with tropical areal-types and East Asia distributes.There are two new taxon in the record flora.And there are 12 species which are rare and endangered.3 species,4 variety plants was not record in the Flora of Shanxi Province.70% of the plants recources in this flora are available for utilization.Reasonable developing.
