| 摘 要： | 对民勤天然柠条群落进行野外调查与群落物种多样性分析，结果表明：民勤天然柠条群落物种多样性水平较低，结构简单，物种组成单一，主要物种为小灌木，伴有少量的1年生及多年生草本植物；群落优势种柠条的重要值远高于其他伴生种，唐古特白刺、泡泡刺为天然柠条群落的主要伴生种；柠条种群及主要伴生种群大多呈集群分布格局。

| Abstract: | The species diversity of the natural communities of Caragana korshinski in Minqin County,Gansu Province was studied based on the field survey.The results showed that the species diversity of the natural communities of C.korshinski in Minqin County was low,the community structure was simple with less species composition.The main species were small shrubs growing together with some annual or perennial herbaceous plants.The importance value of Caragana korshinski as dominant species of the community was much h... |
