内蒙古黑里河自然保护区维管束植物区系研究

Research on Vascular Bundle Flora of Heilihe National Reserve in Inner Mongolia

对内蒙古黑里河自然保护区维管束植物区系进行了研究,结果表明,黑里河自然保护区有维管束植物777种,隶属96科377属。其中蕨类植物12科18属32种;裸子植物1科3属3种;被子植物83科356属742种。该区维管束植物区系特征为:优势现象明显;地理成分复杂;区系具古老性;珍稀植物种类丰富;植被分布规律明显。近年来人为因素使该地区生态系统和物种资源受到不同程度破坏。指出黑里河自然保护区地处生态脆弱带,生态系统中各因素之间的依存关系较为敏感,需要科学地管理,有效地保护,合理地开发和利用。

The vascular bundle flora of Heilihe national reserve in Inner Mongolia was researched. The result showed that there were 777 species in vascular bundle plant, attributing to 96 families and 377 genera. Thereinto, 12 families,18 genera and 32 species belonged to fern, 1 families, 3 genera and 3 species belonged to gymnosperm and 83 families, 356 genera and 742 species belonged to angiosperm. The characteristcs of the vascular bundle flora of Heilihe national reserve in Inner Mongolia were that the phenomenon of superiority was evident, the component of geography was complicated, the flora was old, the rare foliage species were abundant, and the rule of vegetation distributing was evident. Lately, the native ecosystem and species resources were destroyed because of artificial factor. Heilihe national reserve lied zoology frail zone, and the dependence relation of different factors was sensitive. So Heilihe national reserve should be paid attention to scientific administer, effectual protect and logical exploitation and use.
