摘要
废弃矿山生态环境治理的主要任务是边坡稳定性治理和植被恢复。常绿阔叶林是浙江原生的地带性植被,浙江矿山边坡植被恢复的目标宜为常绿阔叶林,但受边坡特殊条件和物种生长对策的限制,阶段性的目标宜创造原生植被自然更新的良好条件,逼近周边植被类型并成一定的相关性,相关系数越大,森林化程度越高,群落的稳定性就更好。要把握最终和阶段两个目标,如果阶段目标明确,最终目标模糊,就很难把握恢复的效果。建议营造以美丽胡枝子等乡土树种为优势的边坡森林化阶段性植被,采用种子喷播、容器苗建植等多种营造方法。
The main target of ecological environment improvement for abandoned mine is side slope stability control and vegetation recovery. Ever green broad leaf forest, the exotic zonal vegetation in Zhejiang province is the target forest for the improvement of abandoned mine slope. But limited by special site and growth condition, selection of plant for envi- ronment improvement should be similar with nearby ones, thus making the future community stable. Exotic species like Lespedeza thunbergiiwere recommended for the plantation by seed spray and container seedling plantation.
