广西内河航道建设对水生态环境影响及对策

Impact of inland waterway construction on water ecological environment and countermeasures in Guangxi

航道工程建设是在水域内施工,在建设过程中,由于水体扰动、水域面积占用等行为,对水质、水生态、水文、河底地形等产生一系列影响,尤其是对水生态环境敏感区的影响。结合多年广西内河航道建设对水生态环境影响的经验,分析航道建设对广西内河常见的水源保护区和鱼类“三场”两类水生态敏感区的环境影响,并提出了有效应对措施,为后期航道建设对水生态环境敏感区的保护提供参考。

Navigation waterway construction is carried out in the waters.Waterway construction renders impact on water quality,water ecology,hydrology and river bottom topography due to water disturbance and occupation of water area etc.Combined with multiple years of experience in the impact of inland waterway construction on water ecological environment in Guangxi,the authors analyze the impact of waterway construction on the water ecology sensitive areas frequently seen on inland rivers of Guangxi,i.e.the water source protection areas and fish wintering grounds,spawning grounds and feeding grounds,and put forward effective countermeasures,so as to provide reference for the protection of sensitive areas.
