金属矿山水土流失防治中植物措施的特殊作用

Special role of plants in soil erosion control measures of metal mines

金属矿山在开采过程中对矿区及周围的生态环境造成了较为严重的重金属污染。因此,在金属矿区开展重金属污染治理对于减轻重金属危害、确保农作物安全生产、保障人民健康,具有长远而重大的意义。笔者就植物措施在金属矿山水土流失防治中的特殊作用作一简要概括,对金属矿山植物措施防治水土流失的现状、植物修复技术的特点、超富集植物的筛选方法及筛选成果、影响植物措施在金属矿山水土流失防治中发挥特殊作用的因素等作了介绍,以期能为金属矿山的生态环境治理提供参考。

In the course of the exploitation of heavy metals mining,the mining area and the surrounding environment are affected from serious pollution of heavy metals.Therefore,It is very important to reducing the hazards of heavy metals in the metal mining area for the crop production safety and people's health.In this paper,the special role of plants to prevent soil erosion in the metal mine was briefly summarized.The soil erosion of the status in metal mine,the characteristics of phyto-remediation technology,ultra-enrichment plant section and the results,and the impact of other factors on special role of plants in the metal mine were presented with an expectation to provide reference for governing the ecological environment of metal mines.
