Abstract

Resilience, which can also be described as absorbing capacity, describes the amount of change that a system can undergo in response to disturbance and maintain a characteristic, self-sustaining regime of functions, processes, or sets of feedback loops. Rivers exhibit varying levels of resilience, but the net effect of industrialized anthropogenic alteration has been to suppress river resilience. As changing climate alters the inputs to rivers and human modification alters the morphology and connectivity of rivers, restoration increasingly considers how to enhance resilience. Characteristics that underpin river absorbing capacity include natural regimes, connectivity, physical and ecological integrity, and heterogeneity. River management emphasizing channel stabilization and homogenization has reduced river absorbing capacity. We propose that the paths to restoring rivers include defining relevant measures of absorbing capacity and understanding the scales of restoration and the sociopolitical elements of river restoration. We provide a conceptual framing for choosing measures that could be used to assess river absorbing capacity.
增强河流的自然吸收能力,恢复其复原力
恢复力也可以被描述为吸收能力,它描述了一个系统在应对干扰时可以承受的变化量,以及维持功能、过程或反馈回路的自我维持机制的特性。河流表现出不同程度的恢复能力,但工业化人为改变的净效应抑制了河流的恢复能力。气候变化改变了河流的输入量,人类活动改变了河流的形态和连通性,因此,修复工作越来越多地考虑如何提高河流的恢复能力。支撑河流吸收能力的特征包括自然系统、连通性、物理和生态完整性以及异质性。强调河道稳定和同质化的河流管理降低了河流的吸收能力。我们建议,恢复河流的途径包括定义相关的吸收能力衡量标准,了解恢复的尺度以及河流恢复的社会政治因素。我们为选择可用于评估河流吸收能力的措施提供了一个概念框架。

期刊介绍: BioScience is a monthly journal that has been in publication since 1964. It provides readers with authoritative and current overviews of biological research. The journal is peer-reviewed and heavily cited, making it a reliable source for researchers, educators, and students. In addition to research articles, BioScience also covers topics such as biology education, public policy, history, and the fundamental principles of the biological sciences. This makes the content accessible to a wide range of readers. The journal includes professionally written feature articles that explore the latest advancements in biology. It also features discussions on professional issues, book reviews, news about the American Institute of Biological Sciences (AIBS), and columns on policy (Washington Watch) and education (Eye on Education).
