| 摘 要： | 以野外样方调查数据为基础,调查了太子河干流河岸带植物物种的组成、种类和外貌,应用重要值计算了太子河河岸带植物丰富度指数、多样性指数、均匀度指数、优势度指数,分析了其物种的多样性差异,从而为太子河河岸带的生态修复提供理论和技术依据.结果表明:太子河干流河岸带23个植物样方中,共有36科124属201种,群落物种组成较为丰富,但仅限于草本植物;物种组成以菊科、禾本科、蓼科、莎草科、蔷薇科植物为主,植物种类以灯心草、菵草、狭叶水蓼、野稗、看麦娘、水蓼、酸模、丝叶蒿、薹草、中华结缕草、散穗早熟禾、东方藨草等为主;太子河干流河岸带植物物种结构简单,物种组成较少;植物物种多样性水平较低,从多样性指数的数量特征来看,Patrick丰富度指数的变化范围为3.00—28.00,Pielou均匀度指数的变化范围为0.66—0.89,Simpson多样性指数的变化范围为0.54—0.91,Shannon-Wiener多样性指数的变化范围为0.86—2.73,Simpson优势度指数的变化范围为0.09—0.46.太子河干流河岸带受到的人为活动干扰,如农业生产、挖沙等,降低了物种多样性水平.

| Abstract: | The species diversity is an important trait of plant ecological adaptive strategy. The plant community of riparian zone along Taizi River plays an important role in the stabilization of plant composite. However,the species diversity of riparian zone along Taizi River is quite poorly known. The objectives are to investigate the species diversity of the understory of riparian zone along Taizi River in order to provide the theory of ecological restoration and technical basis. The diversity of plant species in ... |
