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.
恢复力，也可被描述为吸收能力，指的是一个系统在受到干扰时能够承受的变化量，并维持其功能、过程或反馈回路集的特征性、自我维持状态。河流展现出不同程度的恢复力，但工业化的人为改变所产生的总体影响是抑制了河流的恢复力。随着气候变化改变了河流的输入，以及人类改造改变了河流的形态和连通性，河流恢复越来越多地考虑如何增强恢复力。支撑河流吸收能力的特征包括自然状态、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。我们认为，恢复河流的途径包括确定吸收能力的相关衡量标准，理解恢复的尺度以及河流恢复的社会政治因素。我们提供了一个概念框架，用于选择可用于评估河流吸收能力的措施。
