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 .
