摘要
黄河流域生态保护和高质量发展已上升为国家重大战略。从生态系统保护和河流健康维护角度,分析评估了黄河下游生态调度效果,结果显示:下游重要断面的生态基流、敏感期生态流量、生态廊道功能维持及湿地生态流量得到全面满足;与2009—2010年相比,2020年河南段、山东段监测到的鱼类分别增加了16、12种;2020年下游河道湿地面积比2019年增加了7.2%;2020年河口地区代表性湿地芦苇沼泽湿地面积达到1.73万hm2,超过20世纪90年代初自然保护区建立时1.4万hm2的水平,生态调度在下游及黄河三角洲生态系统的保护和修护中发挥了重要作用。同时指出,生态保护与修复是一个长期过程,要继续深化黄河下游生态调度和加强生态调度效果评估。
Ecological protection and high⁃quality development of the Yellow River basin has become a major national strategy.From the per⁃spective of ecosystem protection and river health maintenance,this paper analyzed and evaluated the effect of ecological management in the lower Yellow River.The results show that the ecological base flow,the ecological flow in the sensitive period,the functional maintenance of the ecological corridor and the wetland ecological flow in the important sections of the lower reaches are fully satisfied.Compared with the pe⁃riod of 2009-2010,the number of fish species detected in Henan section and Shandong section has been increased by 16 and 12 respectively.The wetland area of the downstream river has been increased by 7.2%compared with that of 2019.The representative wetland area of reed marsh in estuarine area reaches to 17,300 hectares,exceeding the level of 14,000 hectares when the nature reserve was established in the early 1990s,playing an important role in the protection and restoration of the ecosystem of the lower reaches and the Yellow River delta.At the same time,it also points out that ecological protection and restoration are a long⁃term process and puts forward some suggestions on deep⁃ening ecological regulation in the lower reaches of the Yellow River and strengthening effect evaluation.
