黑龙江、松花江航道疏浚工程对水生生物环境影响研究

针对黑龙江、松花江航道疏浚工程对水生生物环境影响问题,提出了疏浚工程对水生生物的影响,包括对浮游植物的影响、对浮游动物的影响、对底栖动物的影响和对水生植物的影响,将产生泥沙、悬浮物、噪音、底质改变及机械废水、固体垃圾等,进而对鱼类资源的影响分析,包括施工噪音对鱼类的影响,如对鱼类栖息地的影响、对鱼类摄食生长的影响、对鱼类产卵行为的影响、悬浮物对鱼类生存的影响、对鱼类卵、苗的影响和对鱼类洄游通道的影响。

Environmental Impacts of Heilongjiang and Songhua River Waterway Dredging Projects on Aquatic Organisms

Focused on the impacts of Heilongjiang and Songhua River waterway dredging projects on aquatic organisms, this paper put forwards the influences of dredging engineering on phytoplankton, zooplankton, benthic animals, and the aquatic plants. The influences of the sediment, suspended solids, and noise, bottom change and mechanical wastewater, solid waste, etc. were analyzed. It also discussed the influence on fish resources, including the influence of construction noise on fish, such as its impacts on fish habitat, feeding, fish growth, fish spawning behavior. The study analyzed the influence of suspended solids on fish, fish eggs, seedlings and fish migration channels.
