摘要
南方离子型废弃矿山生态治理打造复绿、水土保持、水质改善、土壤改良和经济产出的综合治理模式。现以新造植油茶林为主,搭配4种草本植物进行试验种植,以探索适合南方离子型稀土采矿迹地的经济型植被重建模式。通过采集油茶存活率、冠幅、树高、地径及地表植被覆盖率、水土流失控制效果等数据,分析植物搭配对采矿迹地的适应性、影响性。结果表明:"油茶+马唐草"和"油茶+大豆"的植物搭配方法更适宜在采矿迹地生长。对同类其他采矿迹地的研究有借鉴作用。
The ecological management of ion-discharged mines in the south has created a comprehensive management model for re-greening,soil and water conservation,water quality improvement,soil improvement and economic output.The new planted oil tea forest is mainly used,and four kinds of herbaceous plants are used for experimental planting to explore an economical vegetation reconstruction model suitable for southern ion-type rare earth mining sites.Through the collection of oil tea survival rate,crown width,tree height,ground diameter and surface vegetation coverage,soil erosion control effects and other data,the adaptability and influence of plant collocation on mining sites were analyzed.The results showed that the planting method of'oil tea+crabgrass'and'oil tea+soybean'is more suitable for growing in mining sites.It can be used as a reference for the study of other similar mining sites.
