赣南废弃稀土矿区植被恢复模式试验

Experiments on abandoned rare earth mining area's vegetation restoration mode in southern Jiangxi province

为了提高赣南废弃稀土矿区植被恢复效果,改善废弃稀土矿区的生态环境,选用5种不同植被恢复模式进行3年的试验。通过分析其成活率或保存率、郁闭度、地表植被覆盖度、土壤改善情况,研究各模式对赣南废弃稀土矿区植被恢复的影响,从而筛选出最佳植被恢复模式。结果表明:乔灌草配置模式(A5):构树+胡枝子+香根草最适宜该矿区植被恢复。为赣南废弃稀土矿区植被恢复提供理论依据,加快促进赣南苏区振兴发展生态建设,为赣南等南方矿区环境治理提供科技支撑。

In order to improve the restoration effect of the abandoned rare earth mining area＇s vegetation in southern Jiangxi province, and improve the ecological environment of abandoned rare earth mining area, five different vegetation restoration patterns were chosen to conduct trials for three years. By analyzing the vegetations＇ survival or saving rate, canopy density, vegetation cover, soil improvement, various patterns＇ effects on abandoned rare earth mining area＇s vegetation restoration were investigated, further, the best vegetation restoration mode were screened ont. The results show that the configuration mode with tree, shrub and grass （As）： mulberry ＋ Lespedeza ＋ Vertiveria zizanioides is most suitable for the vegetation restoration in this mining area. The findings provide a theoretical basis for abandoned rare earth mining area＇s vegetation restoration in southern Jiangxi province, accelerate the promotion and ecological construction of the Soviet Areas of Southern Jiangxi, and provide a scientific and technological support for southern Jiangxi province and other southern mining environmental governance.
