摘要
"南水北调来水调入密云水库调蓄工程"建成运行后,密云水库的水位上升和南水北调来水汇兑的共同作用将对密云水库的水质和水生生物产生影响,分析结果表明:调水初期机械混合作用将导致密云水库阴、阳离子降低,而氮、磷等营养元素则呈上升趋势;调水将使密云水库浮游植物种类和数量增加;水库中的大型水生植物和鱼类都将在调水初期经历减少的过程,但随着水位逐步稳定,更大的水域面积将有利于水生植物和鱼类的生长繁殖。
After the construction of the project "Regulation and Storage of Water fi'om South-to-North Water Transfer Project in Miyun reservoir", the interaclion of water level rising and different water resources exchanging will influence water quality and aquatic: organisms of Miyun reservoir. The analysis shows that, the water mechanical mixing in the preliminary stage will result in the deerease of anion and cation concentration while nutrients such as nitrogen and phosphorus rise. Water transferring will make algal species and quantity increase. Aquatic plants and fishes in the reservoir will experience the process of reduction at the beginning of the water diversion. As the water level gradually becomes stable and high, the larger water area will he conducive to the growth of aquatic plants and fish breeding.
