江西省赣州市龙南县稀土矿已开采40多年,造成了严重的生态环境破坏和水土流失等问题.为了赣州市稀土资源整合后矿区的生态环境综合治理,选择矿区内未开采区的6个植物群落样地进行植物种类调查,探寻矿区植被本底情况.共发现野生植物物种共33种,主要植物种类为马尾松 、杉木 、枫香 、盐肤木 、五节芒草等,优势物种为木本植物.鉴于矿山植被恢复的基本原则之一是优先选择乡土物种,以防止外来物种入侵,矿区内未开采区植被群落调查可为龙南稀土矿的植被恢复提供参考.
Study on the characteristics of plant community in the unmined area of rare earth mine in Longnan
The 40 years' mining activities of rare earth mine in Ganzhou have produced severe eco -environment destruction and soil erosion problems .For the integrated renovation of the rare earth resources' ecological environment after its integration in Ganzhou ,6 sample plots of plant community in the unmined area were choosen for the plant species investigation to explore the baseline vegetation situation in the mining area .33 wild plant species were found ,and the main plant species were pinus massoniana , cuninghamia lanceolata ,pterocarya stenoptera ,rhus chinensis ,miscanthus floridulus ,etc .The dominant species are woody plant .Since one of the basic principles of vegetation restoration in the mine area is to select native species to prevent invasion of exotic species ,the plant species investigation in the unmined area will provide reference for the vegetation restoration of the rare earth mine in Longnan city .
