沙石矿的无序开采,造成了蓟县及周边山区大面积山体破损、植被破坏、水土流失、扬沙起尘等生态环境问题。为改善生态环境,采取人工垒砌坝台、爆破挖坑、客土回填整地;选用抗旱性植物材料,乔、灌、草、爬藤树种配置;培育容器苗木;精细栽植;地面全覆盖等工程技术和生物治理相结合的综合措施,解决了采矿迹地生态修复的技术难点,实现了乔、灌、草、爬藤植物立体复层绿化、多元化生态修复目标。
Sandy mine disorderly mining, resulting in Jixian and the surrounding mountainous areas of large mountain damage, vegetation damage, soil erosion, dusting and other environmental issues such as sand. In order to improve the ecological environment, we should adopt artificial basement to build dams, blasting ditches and earthquakes for backfilling; selecting the plant materials for drought resistance, such as planting of Qiao, Irrigation, grasses and climbing vines; cultivating seedlings of containers; fine planting; Technology and biological management combined to solve the technical problems of ecological restoration of mining sites to achieve the Joe, irrigation, grass, climbing plants three-dimensional multi-layer afforestation, diversification of ecological restoration objectives.
