摘要
鱼类群落结构影响着湖泊的水质和水体的自净能力。分析了鱼类在浅水湖泊生态系统的作用,以及对富营养化的影响,并提出了基于富营养化控制的鱼类群落管理对策,即通过放养滤食性、肉食性鱼类以及减少食浮游动物和杂食性鱼类等方式,对湖泊鱼类群落进行调控,以优化湖泊生态系统结构,增强水体自净能力和改善水质。
Water quality and self-purification capability of lakes are greatly influenced by the community structure of fish. In this paper the role of fish in shallow lake ecosystems and eutrophication was analyzed. The fish management raeasures were also proposed in order to control lake eutrophication, i. e. stocking filter-feeding and piscivorous fish,and reducing omnivorous and zooplanktivorous fish in order to change the structure of fish community,and thus to manipulate the ecosystems,enhance serf-purification capability and improve water quality of the lake.
