| 摘 要： | 通过在西鄂尔多斯地区几年的植物标本采集以及参考前人对该地区植物名录的记载,对西鄂尔多斯地区野生维管植物种类组成、生活型、水分生态类型及植物区系地理成分进行了分析研究。结果表明:①西鄂尔多斯地区的野生维管植物共有64科、215属、433种;②植物的生活型以多年生草本为主,占52.66%,其他为乔木占0.69%、灌木占14.09%、半灌木占6.93%、一或二年生草本占24.25%、草质藤本占0.92%,类短命植物占0.46%;③植物的水分生态类型以旱生（包括强旱生、旱生和中旱生）为主,占49.42%,中生植物（包括旱中生、中生、湿中生）占47.58%,湿生植物占1.85%,水生植物仅占1.15%;④西鄂尔多斯地区植物区系地理成分组成复杂多样,在温带区系性质为主体的背景下,受欧亚草原区系、东亚森林区系、亚洲中部荒漠区系及古地中海区系的影响。

| Abstract: | The species composition,life form,water ecotype composition and flora composition of wild vascular plants in West Ordos were studied based on collection of plant samples for several years in West Ordos and according to checklist of plants by predecessor about this region.Results show that:(1) The total of 433 vascular plants species belong to 215 genera and 64 families.(2) The types of life form are mainly perennial herb,accounting for 52.66%;others are trees,shrubs,hemi shrubs,one or biennial herbs,herbal climbers and ephemeroid plants,accounting for 0.69%,14.09%,6.93%,24.25%,0.92%,and 0.46% of all species in this region respectively.(3) The types of water ecotype include xerophyte(49.42%),mesophyte(47.58%),hygrophyte(1.85%) and hydrophyte(1.15%);the xerophyte and mesophyte plants play a dominant role.(4) The flora composition and geographical element of vascular plants are complex and diverse.It show significant temperate flora nature and is also affected by the Eurasian steppe flora,East Asia forests flora,Asian central desert flora and the ancient Mediterranean flora. |
