摘要
[目的]为小兴安岭菊科植物资源的保护和合理开发利用提供理论依据。[方法]采用野外调查和标本鉴定的方法,对小兴安岭菊科植物物种多样性、区系地理成分和经济用途多样性等进行了研究。[结果]该区共有菊科植物126种,隶属48属,且优势属明显,少种属和单种属占总属数的比例分别为37.50%和56.25%。从属层次上表现出典型的温带性质,以北温带成分为主,且没有我国特有属。[结论]小兴安岭菊科植物组成丰富,区系地理成分多样,经济用途多样。
[Objective] To provide theoretical basis for protection,reasonable development and utilization of Asteraceae resources in the Xiaoxing'an Mountains.[Method] Using the methods of field survey and identification of specimen,the species diversity,floristic geography and economic utility diversify of Asteraceae plants in the Xiaoxing'an Mountains were studied.[Result]There were 126 species of Asteraceae belonging to 48 genera. The dominant genera were prominent,and the percentage of minor genus and single genus took 37. 50% and 56. 25% of total number of genera,respectively. Asteraceae plants in the region showed the typical temperate floral characters at genus level,North Temperate type was the dominant. And there was no Chinese endemic genus.[Conclusion] Asteraceae plants in the Xiaoxing'an Mountains have abundant plant components,many geographical elements of flora and various economic utility.
