摘　　要：高岭铁矿区位于密云区,自上个世纪70年代起就开始了规模化开采,由于工艺技术落后,对于环境保护意识薄弱,导致了矿区生态环境变恶劣。为了全面评价高岭铁矿区的生态环境,已期未来能合理的进行开采和利用,研究主要是采用现场调查,采样分析方法,开展对水体、土壤地质调查。结果表明:土壤中存在的超标污染源为Cr和Ni,大部分以残渣形式存在,相对稳定;水体中超标的污染源为化学需氧量和硝酸根,影响饮用水质量。对矿区的生态环境需要加强监测和监管,并对周边面源性污染进行治理,保障人居环境安全。Located in Miyun District,Gaoling Iron Mine has started large-scale mining since the 1970s.Due to backward technology and weak awareness of environmental protection,the ecological environment of the mining area has become worse.In order to comprehensively evaluate the ecological environment of the Gaoling Iron Ore District and to reasonably exploit and utilize it in the future,this study mainly uses the field survey and sampling analysis methods to carry out geological survey of water and soil.The results showed that the excessive pollution sources in the soil were Cr and Ni,most of which existed in the form of residue,and were relatively stable.The pollution sources exceeding the standard in the water body are chemical oxygen demand and nitrate,which affect the quality of drinking water.The ecological environment of the mining area needs to be monitored and supervised,and the surrounding non-point source pollution should be treated to ensure the safety of the living environment.
