摘要
湿地植物区系研究是湿地生态保护和恢复的基础,为了深入认识呼伦贝尔市湿地及其生物多样性,分别于2012年和2013年的7~8月,对呼伦贝尔市(47°5′N^53°20′N,115°31′E^126°4′E)主要湿地进行了野外调查。根据调查数据及相关资料,分析了该区的湿地种子植物区系特征。记录了野生种子植物352种5亚种17变种,隶属于65科198属,以多年生草本植物为主。物种较为丰富的科有菊科、禾本科、蔷薇科、毛茛科、豆科和莎草科等,物种丰富的属有柳属(Salix)、蓼属(Polygonum)、薹草属(Carex)和眼子菜属(Potamogeton)等。该区植物区系种的地理成分复杂,包含19个分布区类型20个亚型,温带特征明显,兼具亚寒带-寒带性质,与世界植物区系有普遍的地理联系,尤其与西伯利亚的联系非常密切,包含少量热带成分种,热带亲缘性不明显。
Obtaining a comprehensive understanding of the Flora of the wetlands is the foundation of the conservation and restoration of the wetland ecosystem. In order to obtain a further understanding of the biodiversity of the wetlands in Hulunbuir City, the field surveys about the major wetlands in Hulunbeir City which covers the range from 47°5′N to 53°20′N and from 115°31′E to 126°4′E was conducted from July to August in2012 and 2013, respectively, and the floristic characteristics of seed plants in the area were analyzed based on the survey data and relevant reference. There were 352 species, 5 subspecies and 17 varieties belonging to 198 genera and 65 families within the range of the wetlands in Hulunbuir City, most of which were perennial herbs. The dominant families were Compositae, Gramineae, Rosaceae, Ranunculacea, Leguminoseae and Cyperaceae and the dominant genera were Salix, Polygonum, Carex and Potamogeton. This region exhibited complicated floristic geographical components including 19 types and 20 subtypes. It was characterized with significant temperate features and some subfrigid-frigid, it has widely geographically correlation general with the world flora, especially closely correlated with the flora of Siberia. And some included few species of tropical zone, but the tropical affinity was not obvious.
