摘要
在2014-2015年间对四川省石棉县大岗山水电站影响区域内的种子植物的种类、植被类型等进行了调查与分析,旨在为电站建设后的植被恢复与重建提供参考依据.结果显示:(1)物种多样性较为丰富,该区种子植物有101科、320属、552种;(2)优势科、属明显,以禾本科(Gramineae)、菊科(Compositae)、蔷薇科(Rosaceae)居多;(3)其种子植物包含9种科级分布区类型、15种属级分布区类型及变型,表现出明显的热带性质和一定的温带性质;(4)影响区域内的植被大致可分为5个植被型组、6个植被型、10个群系.
During the 2014 - 2015 years, the species and vegetation types of seed plants in Dagangshan Hydropower Station impacted regions were investigated and analyzed to provide a reference for vegetation restoration and rehabilitation after Hydropower Station construction. The results showed that： （1） The species diversity is rich, There were 552 seed plants species belonging to 101 families and 320 genera in Dagangshan Hydropower Station impacted regions in Shimian County. （2）The dominant families and genera were prominent such as Gramineae, Compositae, Rosaceae. （3） The floristic elements of the seed plants were classified into 9 areal-types at the level of family and 15 areal-types at the level of genus. The temperate components were found to be dominant but the tropical components also owned a little proportion. （4）. the impacted area vegetation could be divided into 5 vegetation type groups, 6 vegetation types, 10 formations.
