摘　　要：通过对内蒙古区域内分布的种、变种、变型和新种统计,得出内蒙古有特有植物27科、57属、89种,其中7变种、7新种和1变型;生活型以草本为主,水分生态型以中生为主;10种以上的特有植物果实类型以蓇葖果、蒴果、翅果、坚果、瘦果和颖果为主,反映了内蒙古特有植物主要分布于山地和荒漠的特点;内蒙古特有植物分布最多的地区是阴山山脉,并以卓资山、狼山为集中,其次为阿拉善高原,第三为贺兰山,之后分别为大兴安岭和鄂尔多斯高原,此外额济纳和锡林郭勒高原特有植物分布也相对集中,东阿拉善-西鄂尔多斯荒漠区,以古地中海孑遗植物为主形成了众多的特有植物群。According to the statistics of species,varieties,variants and new species in different geographical units of Inner Mongolia,there are 27 families,57 genera and 89 species of endemic plants in Inner Mongolia,including 7 varieties,7 new species and 1 variant.Herbs are dominant in life form,mesophytes are dominant in water ecotype,and fruit types of endemic plants are mainly follicle,capsule,samara,nut,achene and caryopsis.More than 10 species of endemic plants reflect the characteristics of mountain and desert distribution.The most endemic plants in Inner Mongolia are the Yinshan Mountains,concentrated in Tazishan and Langshan Mountains,followed by Alxa Plateau and Helan Mountains,followed by the Great Hinggan Mountains and Ordos Plateau,and the Ejina and Xilingol Plateau are also relatively concentrated in endemic plants.In the desert area of East Alashan-West Ordos,a large number of endemic flora have been formed,and the relics of the Paleo-Mediterranean are the main ones.This area is also the concentration area of endemic plants in Inner Mongolia.
