摘要
系统梳理了珠江流域生态水力学研究现状,从珠江流域鱼类资源方面分析了珠江河口、西江以及东江的鱼类时空分布及生境特征;从珠江流域过鱼设施方面总结了竖缝鱼道、丹尼尔鱼道、生态鱼道等鱼道形式研究进展;指出河道栖息地修复以及生态调度是生态水力学的应用方向。聚焦珠江流域生态水力学研究现状与进展,提出珠江流域水生态未来发展方向和解决策略,为未来珠江流域水生态修复提供参考。
This paper makes a systematic review on the current status of ecological hydraulics in the Pearl River Basin,and analyzes temporal and spatial distribution of fish species and features of fish habitat in the Pearl River estuary,the West River and the East River from the perspective of fish resources in the basin.The study results of vertical slit fishway,Daniel fishway and ecological fishway are summarized from the aspect of fish passing facilities in the Pearl River Basin.It indicates that river habitat restoration and ecological regulation are the application trends of ecological hydraulics.By focusing on current situation and progress of ecological hydraulics research,future development direction and strategic solutions of water ecology in the Pearl River basin are proposed,which shall provide references for water ecological restoration in the future.
