| 摘 要： | 通过对官厅水库库区55个表层底泥样品的采样分析，对库区底泥中重金属的存在状态及生态风险进行了评价。通过底泥释放研究，预测了底泥中污染物的释放可能对水体造成的影响。同时对官厅水库库区底泥中重金属及氮、磷的分布状况进行了研究，结果表明，铅的污染主要由历史上上游污水入库所致；而铜、氮、磷污染主要是由于上游入库水体、库区周边的农田及葡萄园使用农药化肥所致。底泥中的重金属较稳定，一般不会对水体造成二次污染。 |

| Abstract: | The existing form and ecological risk of heavy metals were estimated according to the analysis of 44 surface sediments in Guanting reservoir. Distribution of heavy metals, TP and TN was investigated. The results showed that metal sulfide was the main existing form of the heavy metals according to the mole ratio of simultaneously extracted metal (SEM) and acid-volatile sulfide (AVS). The polluted areas were found and the reasons that may cause pollution were discussed. The pollutant of pb was from upstream wastewater. The pollutants of Cu, N and P were caused by chemical fertilizer and pesticide used in the grape park and farmland all around the Guanting reservoir. The effect of pollutants released from sediments to water body was forecast according to simulation emission experiments. |
