摘要
针对大浪淀水库水环境恶化问题,阐述了生物调控技术修复水生生态系统的机理和方法。通过生物调控修复技术对大浪淀水库水生生态系统修复的实施,使大浪淀水库水质由1997年的超V类水逐步调控为2002年的 ～ 类水,营养化程度由1997年的严重富营养降至中营养,效果极为显著。
The paper expounds the organism and methods of the amendment of aquatic ecosystem with biological control technique based on the deterioration of the Dalangdian Reservoir water environment.With the implementation of the biological control technique,the water quality of the Dalangdian Reservoir has gradually improved from degree V in 1997 to degree Ⅰ—Ⅱ in 2002.The serious over-nutrition of the water has been greatly reduced.
