摘　　要：某市矿产资源非常丰富,并且位于某特大城市饮用水源地的上游,依据国家企业环境风险等级评估方法,结合尾矿库的危险性以及尾矿库所处区域环境受体的敏感性,对该市67家企业和500余座尾矿库风险水平进行了分析,划分了企业环境风险源和尾矿库风险等级。结果表明,具有重大环境风险源企业12家,占18%,一般环境风险源企业17家,占25%;全市共有重大环境风险源尾矿库32座,一般环境风险源尾矿库78座,非环境风险源尾矿库410座。进一步探讨了该区域需要监控的环境风险物质、监控对象、监控点位和监控指标,提出了体现"常规监控指标"和"特征污染物监控指标"不同监控级别的企业和尾矿库型环境风险源的监控技术优选方案。The city under research possesses rich mineral resources and is located at the upper stream of the drinking water source of one megacity. With the development of the mining and chemical industries, sudden environmental pollution accidents occurred frequently, and thus the environmental risk problems have attracted more and more attention. Based on the evaluation method of the national enterprise environment risk grading, and in combination with the hazard of tailings and sensitivity of environmental receptors, the risk level of 67 enterprises and more than 500 tailing ponds in the city were analyzed, and the risk grades of the enterprises and tailing ponds were classified. The results showed that there were 12 major risk source enterprises, accounting for 18% of all the investigated enterprises, and 17 general risk source, accounting for 25% of the total. For tailings pond result, there were 32 major risk sources, 78 general risk sources and 410 non-environmental risk sources. Subsequently, the substances, objectives, sites and indexes for monitoring the environmental risk in the area were discussed, and the optimized monitoring technical scheme for enterprises and tailing ponds was put forward. The scheme involves risk evaluation and monitoring of different levels with regard of both regular indexes and typical pollutants indexes, which should effectively improve the risk management level.
