通过提供1986年以前的历史背景，并强调自J-NABS成立以来25年出现的主要主题，我们回顾了关于河流生态系统干扰的思想发展和经验理解，干扰在1986年之前没有很好地纳入流生态学思想，但意识到它的重要性在20世纪80年代初开始出现。雷什等人（1988(4)）在一篇论文中明确了扰动是溪流中一个基本驱动因素的广泛认识，这标志着扰动研究进入了一个密集的时期。我们确定了4个后续研究主题：1)术语和概念的定义以及量化干扰和生态响应的工具的开发；2)干扰复兴，这是一个实证研究急剧增加的时期；3)通过将干扰纳入溪流生态系统的概念模型来形式化溪流中干扰的重要性；尽管在过去25年中，在理解河流生态系统中的干扰方面取得了显著进展，但未来研究的机会很多，活动范围和强度的增加强调了检查干扰之间相互作用以及将生态原则纳入管理和恢复活动的必要性。认识到地貌形式和过程与扰动生态之间的联系，可能会产生新的见解。在政权转移的背景下观察溪流也会带来新的进展，特别是在恢复方面，因为扰动会引起非线性反应，这些努力的成功将有助于提高对溪流和河流的科学理解和管理。
We reviewed the development of ideas and empirical Understanding about disturbance in lotic ecosystems by providing a pre-1986 historic context and highlighting major themes that have emerged in the 25 y since the inception of J-NABS Disturbance was not well incorporated into stream ecological thinking before 1986, but awareness of its significance began to emerge in the early 1980s, as demonstrated by the publication of several classic papers illustrating the ecological consequences of floods Broad recognition of disturbance as a fundamental driver in streams was crystallized by Resh et al (1988(4)) in a paper that marked the beginning of a period of intense research on disturbance. We recognized 4 subsequent research themes 1) definition of terms and concepts and development of tools for quantifying disturbances and ecological responses, 2) the disturbance renaissance, a period during which empirical research increased dramatically, 3) formalization of the significance of disturbance in streams by its incorporation into conceptual models of stream ecosystems, and 4) operationalization of disturbance for management and restoration of streams and rivers Despite remarkable progress toward understanding disturbance in lotic ecosystems in the past 25 y, opportunities for future research are numerous Increasing scope and intensity of activities underscore the need to examine interactions among disturbances and to incorporate ecological principles into management and restoration activities. New insights are likely to arise from recognition of links between geomorphic forms and processes and the ecology of disturbance Viewing streams in the context of regime shifts should also lead to new advances, particularly for restoration, because disturbances can elicit nonlinear responses Successes in these efforts Should contribute to improved Scientific Understanding and stewardship of streams and rivers.
