黄河三角洲生态修复与栖息地保护

The Yellow River Delta Ecological Restoration and Habitat Protection Based on Water and Sediment Regulation

黄河三角洲是我国三大河口中最具生态保护价值的区域。因黄河来水量减少和受河口地区人为干扰影响,长期以来三角洲尤其是河口湿地生态呈持续恶化态势,珍稀濒危鸟类栖息生境受到威胁。实施流域水量统一调度和调水调沙举措,为河口三角洲受损生态系统的水量补给和生态修复创造了条件。通过10余年的黄河水沙调控和河口湿地人工修复,河口流路区的生态状况得到了显著恢复。

The Yellow River delta is the most valuable in ecological protection among the three great deltas in China. Because of the Yellow River runoff decrease and human influence to delta area, the delta wetlands ecosystem especially the estuary wetlands ecosystem has been deteriorating for a long time, posing threats to the habitats of rare ＆ endangered birds. The implementation of integrated water volume regulation and the water-sediment adjustment at the scale of whole river basin created the right conditions for water recharge and ecological restoration of the damaged ecosystem in the delta. Through more than 10 years of water-sediment regulation in the river basin and artificial restoration of estuarine wetlands, the ecological status of river flow path area has been significantly improved.
