成都至宜宾高速公路沿线植被类型及分布特征研究

Vegetation Types and Their Distribution Characteristics Along the Motorway from Chengdu to Yibin

  • 摘要: 本研究对拟建成都至宜宾高速公路沿线植物资源及植被分布情况进行调查,以期为该项目建设的环境影响评价提供现状基础资料,为该项目建设采取合理的环境保护措施提供依据。调查结果表明:调查范围内共有维管植物约125科360属575种,其中有小黑桫椤、金毛狗、油樟等3种国家二级重点保护野生植物;调查区植被类型以人工林、经果林和农作物等栽培植被为主,自然植被相对较少;自然植被类型主要是以柏木和马尾松为主的暖性针叶林,以慈竹、毛竹、斑竹等为主的竹林,以黄荆、构树、盐肤木为主的落叶阔叶灌丛。

     

    Abstract: In this study,investigations were conducted on the plant resources and vegetation distribution along the expressway from Chengdu to Yibin,aiming to provide the current information for the environmental impact assessment of the project construction,and the basis for the project construction to take reasonable environmental protection measures.The results showed that there were about 575 species of vascular plants in the scope of the investigation,belonging to 125 families and 360 genera,including Alsophila metteniana, Cibotium barometz,and Cinnamomum longepaniculatum(3 species National key protected wild plants).The vegetation types of investigation areas were dominated by cultivated vegetation which was composed of artificial forest,economic forest and crops,and natural vegetation was relatively small.The natural vegetation type was mainly warm coniferous forest whose main species were Cupressus funebris and Pinus massoniana,bamboo forest mainly included Neosinocalamus affinis, Phyllostachys heterocycla, Phyllostachys bambussoides,etcetera,and deciduous broadleaf shrubs were principally composed of Vitex negundo, Broussonetia papyrifera, Rhus chinensis,etc.
