高岭土矿区植被恢复与生态效应研究

以福建省闽清县高岭土矿区为例,选择了马尾松、胡枝子、桃金娘、茶树、绿竹、香根草、五节芒等作为生物复垦的先锋植物,并采取不同试验处理,经过3 a时间,对其生长和土壤改良状况进行测定.结果表明,马尾松、胡枝子、茶树、绿竹、香根草、五节芒乔灌草相结合的植物群落配置,结合熟土回填的处理,有利于植物较快生长,能较快地改善土壤肥力,取得较好的生态效益及明显的经济效益.鉴于这几种植物在亚热带的广布性,认为它们是亚热带高岭土矿区进行植被恢复的首选植物.

Study of Vegetation Restoration on Ecological Effect in Kaolin Mining Region

Take the Kaolin mining land in Minqing Conuty in Fujian Province for example,choose several kinds of species for biological reclamation,such as Pinus massoniana,Lespedza bicolor,Rhodmyrtus tomentosa,Camellia chinense,Sinocalamus oldhami,Vetiveria zizanioides,Miscanthus floriddulus and so on as the vanguard plants,then deal them with different experiments.The growth and conditions of improved soil in three years were determined.The results show that the community collocation of Pinus massoniana,Lespedza bicolor,Camellia chinense,Sinocalamus oldham,Vetiveria zizanioides and Miscanthus floriddulus,and the disposal of backfilling mellow soil in mining region,could be propitious to faster growth of plants.And it also helps to achieve the cultivation and maturation of soil rapidly,improve the soil fertilization,which have degraded,and has obtained obviously ecological and economic profits.These species of plants have a wide range of distribution,so they are the preferred plant species of community collocation in vegetation restoration in Kaolin mining area.
