Study on Plants Community Succession in Land for Coal Gangue Dump in Fushun Mining Area

摘要

On the base of site classification and site quality evaluation of land for coal gangue dump (LCGD) in Fushun mining area, the plants community succession of LCGD were systematically researched and analyzed. The relationship between dominant plants community succession distribution and soil fertility was studied. It was achieved that there existed the regularity of soil fertility influence on plants community succession on LCGD in Fushun mining area. The formation and distributions of natural existing plants community on LCGD were investigated. The plants community succession law was secondary nudation-grass-shrub-forest, which provided reliable evidence to recovery and recultivation of the LCGD in Fushun mining area.
