近70年来黄河流域生态修复历程及系统性修复思考

Ecological restoration of the Yellow River basin in the last 70 years and systematic restoration thinking

  • 摘要: 黄河流域是我国重要的生态安全屏障,在气候变化与人为干扰不断加强下,水资源供需矛盾突出,生态问题凸显,高效生态修复是推进黄河流域生态保护的重要举措。结合新中国成立以来不同历史时期黄河流域自身特点及存在的主要问题,总结出我国不断探索科学治理黄河流域的“水沙调控治水害、水源涵养治断流、系统修复维健康”3个阶段历程。黄河流域通过3个阶段重点工程的生态治理,取得良好的成效,但在流域系统性修复方面仍面临挑战。基于生态修复系统性思维,提出构建包含流域生态空间系统性、生态要素系统性、生态产品价值系统性、生态监管系统性4个方面的系统性修复框架,并在该框架指引下提出黄河流域高水平保护的建议:根据黄河流域上中下游立地条件,开展系统修复治理、分区施策,整体提升流域生态服务供给能力;坚持山水林田湖草沙生命共同体,开展生态要素系统性治理,优化山水林田湖草沙配置;推动形成“自然资源-修复主体-修复模式-修复空间-价值链条”5个维度协同的生态修复下生态产品价值转换的复合系统;以恢复主导生态功能为目标,构建黄河流域生态修复全过程、系统性监管体系。

     

    Abstract: The Yellow River basin is an important ecological security barrier in China. With the continuous strengthening of climate change and human interference, the contradiction between water supply and demand has become prominent and ecological problems have become prominent. Efficient ecological restoration is an important measure to promote ecological protection in the Yellow River basin. Combined with the characteristics and main problems of the Yellow River basin in different historical periods since the establishment of the People's Republic of China, the three stages of continuous exploration and scientific management of the Yellow River basin were summarized, including "water and sediment regulation for controlling water disasters, water source conservation for controlling flow interruption, and system restoration for maintenance health". The ecological governance of the Yellow River basin had achieved good results through the three stages of key projects, but there were still challenges in the systematic restoration of the Yellow River basin. Based on the systematic thinking of ecological restoration, a systematic restoration framework was constructed including four aspects: the systematic nature of watershed ecological space, the systematic nature of ecological elements, the systematic nature of ecological product value, and the systematic nature of ecological supervision. Under the guidance of the systematic restoration framework, the following suggestions were proposed to provide ideas for high-level protection: 1)Based on the site conditions of the upper, middle, and lower reaches of the Yellow River basin, carrying out systematic restoration and governance, implementing policies by different regions, to improve the overall ecological service supply capacity of the basin; 2) Adhering to the life community of mountains, rivers, forests, fields, lakes, grass and sand, carrying out systematic management and optimizing the allocation of ecological elements; 3) Promoting the formation of a composite system for the value transformation of ecological products under ecological restoration, which was coordinated from five dimensions: natural resources, restoration subjects, restoration modes, restoration spaces, and value chains; 4) With the goal of restoring the dominant ecological function, establishing a comprehensive and systematic regulatory system for the ecological restoration process in the Yellow River basin.
