河流生态修复的顶层设计思考

我国河流生态修复工作发展迅速,近年来已在全国范围内大力推行,但从宏观战略方面,仍然缺乏河流生态修复方面的专项顶层设计来指导具体工作。针对这一问题,本文通过文献梳理和分析,提出了河流生态修复顶层设计思路,包括生态现状评价与胁迫因子识别、生态修复基点和修复目标确定、生态修复规划制定、生态修复措施实施、修复后适宜性管理与技术推广等关键技术流程,并结合国内外研究成果和实践经验详细阐述了其中的技术要点和实施建议。该成果可为今后河流生态修复规划、修复工程实践以及修复后管理等工作提供理论指导和参考借鉴。

A thought on top-level design of river ecological restoration

River ecological restoration in China has been rapidly developed in recent years. However, there is still a lack of a special top-level design in macro strategy to guide the restoration work. To address this issue, this paper puts forward a thought on top-level design of river ecological restoration by combing and analyzing previous literatures and case studies. This thought contains series of key technical processes as ecological status assessment and identification of stress factors, the determination of restoration base point and target, restoration planning, implementation of ecological restoration, and adaptive management and technology promotion after restoration. The key techniques and implementation suggestions are expounded in detail based on domestic and foreign research results and practical experiences. The results can provide theoretical guidance and reference for the future ecological restoration planning of river, restoration practice and post-restoration management.
