摘 要:文章对密云水库周边及上游地区(北京境内)的污染状况作了初步评价。研究结果发现密云水库周边及上游地区重金属污染以Cr和Hg为主,牤牛河上游为污染最严重地区,清水河上游、潮河下游放马峪地区、德田沟-崎峰茶地区受Cr元素轻度污染。这些地区土壤重金属污染的主要原因是由于金属矿山不合理堆放的尾砂及废矿石等人为因素所致。On the base of investigation of soil heavy metals content in the up-stream of Miyun Reservoir and around in September, 2002, the pollution status of soil heavy metals, which include Cd, Pb, As, Hg, Cr, Cu, Ni and Zn ,were evaluated according to the Standard of Soil Environment Quality (GB15168-1995).The result showed that pollution of soil metals in the up-stream of Miyun Reservoir was mainly Cr and Hg and the most serious polluted area was Mangniuhe River, the up- stream of Qingshuihe River, Fangmayu and Detiangou areas were lightly polluted. The analysis of soil pollution showed that it was mostly caused by the tailings of metal mine and mine waste stones.It also showed that man-made disturbance is the main cause of soil heavy pollution.
