水库网箱养鱼富营养化生态修复模式研究——以青狮潭水库为例

摘要

In order to control the eutrophication of Qingshitan reservoir effectively and preserve the water quality of drinking water source protection area,this paper proposed to restore the ecological environment of Qinshitan reservoir by fish cage culture based on the present situation of water quality and analysis on eutrophication causes.According to the water environment capacity and geographical features,the reservoir was divided into prohibited area and controlled area.Aquatic ecological restoration was put into effect in area influenced by eutrophication.The ecological restoration mode provided an effective approach to environmental management and decision-making.%为有效控制青狮潭水库富营养化的发展,确保库区及饮用水源保护区水质达标,结合库区水质现状及网箱养鱼对富营养化成因分析,本文提出青狮潭水库网箱养鱼富营养化生态修复模式。根据青狮潭水库水环境容量及水域的地理特点,对库区水域进行分类管理,划分网箱养鱼禁止区和控制区,并对出现富营养化的水域进行水生生态修复,为青狮潭水库水环境管理和决策提供科学依据。
