摘　　要： 矿业活动对矿山地球化学环境及周围的生态系统带来了巨大的环境影响。金属硫化物矿山开采过程中释放出大量的酸性废水,浸滤出大量的重金属离子,它们和固体废弃物已成为金属矿山采选业的三大环境公害和重要的环境污染源。文章述评了这三种污染源的环境地球化学效应,提出需要进一步加强矿山环境的矿物转化过程中环境地球化学信息的提取和识别,揭示复杂条件下酸性矿山废水中金属的形态、转化过程及其生态效应,建立相应地球化学演化模型,为矿山环境治理提供理论依据。 Geochemical environment and ecosystem around mines were greatly affected by mining activities, large amounts of acid mine drainage （AMD） and heavy metal ions were released from metallic sulfide mines in the course of mining, they were three kinds of environmental hazard and important sources of environmental pollution. The paper discussed environmental geochemical effects of the three sources of environmental pollution. Advanced apparatus and instruments should be used to strengthen abstraction and identification of environmental geochemistry information, and to reveal the formation mechanism of acid mine drainage under complex conditions, to reveal speciation and transformation of heavy metals in acid mine drainage and their ecological effect, and establish the geochemical model to predict and prevent the formation of acid mine drainage.
