摘要
露天采矿对区域生态环境会带来一定程度的损害,实施生态修复工程是保障生产型矿山资源开发利用与生态环境和谐共处的必然途径.本研究以福建紫金山高硫型铜金矿采矿境界面为对象,应用松散堆渣边坡土壤改良、岩质边坡原位固化阻隔、立体近自然植被群落恢复3种生态修复技术,使得修复区浅表土壤pH值自2.78～5.05上升至8.21～8.6,由酸性转为弱碱性,有效抑制了土壤酸化,同时磷(P)、钾(K)、钙(Ca)、镁(Mg)等矿质营养元素含量明显增加.紫金矿业采用矿山环境治理和景观资源融合的生态修复模式,打造了一个集矿业开发、森林景观、科普研学为一体的近郊型国家矿山公园.研究成果为有色金属矿山采矿境界面高陡边坡生态修复治理提供借鉴.
Abstract
To a certain extent,open-pit mining is absolutely harmful to the regional ecological environment,so it is necessary to implement ecological restoration projects,which can ensure the development and utilization of productive mine resources and the harmonious coexistence with the ecological environment.In this study,the min-ing boundary surface of high-sulfur copper-gold deposit in Zijinshan,Fujian Province was taken as the object,and three ecological restoration technologies were applied,namely,soil improvement of loose slag slope,in-situ curing of rock slope and restoration of near-natural vegetation community.The pH value of shallow soil in the restoration area increased from 2.78-5.05 to 8.21-8.6,and the pH value changed from acidic to weakly alkaline.The soil acidification was effectively inhibited,and the contents of phosphorus(P),potassium(K),calcium(Ca),magnesium(Mg)and other mineral nutrients were significantly increased.Zijin Mining adopts the ecological restoration model of integrating mine environmental management and landscape resources to create a suburban national mine park integrating mining development,forest landscape and science popularization and research.The results can provide reference for ecological restoration and management of high and steep mining boundary slopes in non-ferrous metal mines.
