| 摘 要： | 摇蚊幼虫(红虫)在城市供水系统中的出现,成为困扰水厂正常生产运行的又一水处理难题.首先对其生理特性与环境因子之间的关系进行了论述,然后从生态学角度出发,利用生态群落中的食物链关系,分析了富营养化水体中摇蚊幼虫大量孳生的原因.在此基础上提出了利用合理的生物操纵技术,通过鱼类与水生生物间的"下行效应",以达到恢复生态平衡并控制摇蚊幼虫孳生为目的的生态治理方案.

| Abstract: | Chironomus larva(red worm) has become a new problem in the water supply plant because it is difficult to be effectively removed by conventional methods.The extensive investigations were made into the reason of its excessive propagation in the eutrophication of water body by analyzing the relationship between its physiological characteristic and environmental factors,and food chain in biocoenosis.According to ecological viewpoint,the use of the biomanipulation technique utilizing the top-down effect between fish and aquatic organisms is suggested to restore ecological balance and control the excessive propagation of chironomus larva. |
