连通性描述了物质和生物体在自然系统中空间定义的单元之间移动的程度。河流连通性通常以河流廊道和流域内的纵向、横向和垂直维度来描述，并且可以概念化为在不同时间和空间尺度上从完全连接到断开的连续体。连通性的明确表征有助于理解短期局部通量率和更大范围内推断通量之间的差异。连通性还强烈影响河流对自然和人类干扰的响应。对连通性的研究有助于认识跨越传统学科界限的过程，以及理解河流内的非线性行为和滞留。增强识别、量化和预测创建和维持连通性过程的能力是河流有效管理的组成部分。
Connectivity describes the degree to which matter and organisms can move among spatially defined units in a natural system. River connectivity is typically described in longitudinal, lateral, and vertical dimensions within the river corridor and the watershed and can be conceptualized as a continuum from fully connected to disconnected over diverse temporal and spatial scales. Explicit characterization of connectivity helps understanding of disparities among short-term, local rates of flux and inferred fluxes over larger scales. Connectivity also strongly influences the response of rivers to natural and human disturbances. Investigations of connectivity facilitate the recognition of processes that cross traditional disciplinary boundaries, as well as understanding of nonlinear behavior and retention within rivers. Enhancing the ability to identify, quantify, and predict the processes that create and maintain connectivity is integral to the effective management of rivers.
