摘要

以保护和恢复内陆鱼类为目标的河流恢复计划已有几十年的历史，但由于缺乏监测和报告，对过去恢复行动的评估和总结一直受到限制。鉴于对恢复行动进行监测和系统审查的呼声日益高涨，我们对恢复行动在改善长期存在且日益突出的压力因素对河流鱼类造成的状况方面所产生的影响很感兴趣。我们的目标是：(1) 确定哪些压力因素是河流修复工作的目标；(2) 确定已发表的研究中阐明修复目标和开发比较监测设计以评估修复对鱼类影响的比例；(3) 进行荟萃分析以综合鱼类对修复项目的反应。我们通过全球系统回顾和荟萃分析，评估了过去十年发表的同行评审论文中增加鱼类密度和丰富度的恢复效果。我们发现，修复行动主要通过改善溪流生境（37%）、增加溪流纵向连通性（26%）和增加洪泛区横向连通性（9%）来解决主要压力因素。虽然有 81% 的研究采用了比较监测设计（即监测前/监测后和对照/影响）并说明了恢复目标，但其中只有 40% 的研究报告了足够的数据，因此被纳入了荟萃分析。与改善溪流生境和增加洪泛区连通性相比，增加溪流内连通性的项目对鱼类密度和丰富度的积极影响最大。恢复后的时间和恢复规模（即地理足迹）对鱼类响应效应大小的预测作用不强。不同类型项目的恢复效果差异很大。参与荟萃分析的研究作者通常认为，监测的空间或时间范围、凌驾于集水区之上的条件以及重新定居的可能性是造成恢复结果的变异性和有效性的原因。对这些因素和其他协变量进行系统报告有助于指导恢复评估过程，并提供有价值的研究见解。尽管对监测的重视程度有所提高，但不完整的数据报告限制了可纳入定量荟萃分析的研究数量。持续强调为恢复目标、项目监测、数据报告、信息共享和合作项目设定具体标准（如鱼类反应的可测量结果），可能会继续提高对恢复效果的认识，并将其应用于未来的工作中。我们的研究结果可用于为河流恢复工作者提供基于证据的信息支持，以评估相互竞争的恢复优先事项的成本效益比，并为河流鱼类的恢复规划和实施提供信息。

期刊介绍： Freshwater Biology publishes papers on all aspects of the ecology of inland waters, including rivers and lakes, ground waters, flood plains and other freshwater wetlands. We include studies of micro-organisms, algae, macrophytes, invertebrates, fish and other vertebrates, as well as those concerning whole systems and related physical and chemical aspects of the environment, provided that they have clear biological relevance. Studies may focus at any level in the ecological hierarchy from physiological ecology and animal behaviour, through population dynamics and evolutionary genetics, to community interactions, biogeography and ecosystem functioning. They may also be at any scale: from microhabitat to landscape, and continental to global. Preference is given to research, whether meta-analytical, experimental, theoretical or descriptive, highlighting causal (ecological) mechanisms from which clearly stated hypotheses are derived. Manuscripts with an experimental or conceptual flavour are particularly welcome, as are those or which integrate laboratory and field work, and studies from less well researched areas of the world. Priority is given to submissions that are likely to interest a wide range of readers. We encourage submission of papers well grounded in ecological theory that deal with issues related to the conservation and management of inland waters. Papers interpreting fundamental research in a way that makes clear its applied, strategic or socio-economic relevance are also welcome. Review articles (FRESHWATER BIOLOGY REVIEWS) and discussion papers (OPINION) are also invited: these enable authors to publish high-quality material outside the constraints of standard research papers.
