【摘要】 黄河河口是黄河流域生态类型和生物多样性最丰富的区域之一，是黄河流域生态保护和高质量发展的重点区域。针对20世纪黄河断流引发的河口生态系统退化和受损局面，开展了黄河生态调度，实施河口生态修复，通过保障生态基流、提高敏感期生态流量、加大全年生态水量等措施，有效提高了三角洲区域生物多样性，维护了生态系统良性循环，促进了河口生态环境的整体复苏。更多还原

【Abstract】 The Yellow River estuary has the most abundant ecological types and biodiversity in the Yellow River Basin. It is crucial for ecological protection and high-quality development of the basin. In view of the degradation and damage of the estuarine ecosystem caused by dry up of the river in the 21st century, the focus has been placed on ecological regulation for estuarine restoration. Through measures such as securing ecological base flow, increase of ecological flow in the sensitive period and annual ecological flow, the biodiversity of the delta has been greatly enhanced. An overall recovery of the estuarine eco-environment has been found by maintaining virtuous cycle of ecosystem.更多还原
