【摘要】 2001年的调研结果显示,由于网箱养鱼的影响,密云水库内湖已成为富营养水体,库区水体处于中营养水平,但有向富营养化发展的趋势.内湖水体通过侧渗、扩散等途径与库区水体进行物质交换.当水位达到150m以上时,水漫过相隔的窄坝,内湖与库区连为一体,内湖对库区的污染加重,内湖是库区的内污染源.应取消内湖的网箱养鱼,减少内源污染,稳定密云水库水质.更多还原

【Abstract】 Monitoring data in 2001 indicate that inner lake in Miyun Reservoir has reached eutroph-ication because of pollution of net-cage fishculture. The main water body of reservoir belongs to mesotrophication and tends to be eutrophication. The water body of inner lake exchange substance with main water body of reservoir through permeation and spread. When the water lever is over 150m, the waters between water bodies are linked together. Inner lake pollutes reservoir region seriously. Inner lake is a pollution source in Miyun Reservoir. For stabilizing water quality of Miyun Reservoir, it is necessary to stop activity of net-cage fishculture in inner lake.更多还原
