摘要
密云水库近20年的网箱养鱼作业在网箱养鱼区积累了大量的底泥残余物。这些营养源为密云水库的重要污染源之一。对密云水库网箱养鱼区的累计沉积营养物量进行了估计,并分析了其在水库中的释放,从而论述了去除网箱养鱼底泥残留物的必要性。最后对清挖网箱养鱼区底泥残留物进行了技术分析。
In the cage fishery areas of Miyun Reservoir, a great amount of residua had accumulated after nearly 20 years cage fishery, which acted as a major nutrient source. So it is urgent to remove the residua for the eutrophication control. The paper estimated the amount of the residua, and analyzed its contribution to the eutrophication. In the end, the techniques to remove the residua are discussed.
