河流水质对于生态系统健康和水安全至关重要，但在气候风险评估中，气候变化导致的河流水质恶化往往被忽视。在这里，我们回顾气候变化如何通过持续、渐进的变化和偶发、强烈的极端事件影响河流水质。尽管这些变化的幅度、强度和持续时间各不相同，但它们调节了陆地和河流的结构和水文生物地球化学过程，从而重塑了陆地-河流的连通性和河流水质。为了提高对未来气候水质的了解和预测能力，必须将土地和河流视为相互关联的系统。优先考虑极端气候下的研究也很重要，因为极端气候下的水质动态经常挑战现有的理论和模型，并要求概念范式的转变。
River water quality is crucial to ecosystem health and water security, yet its deterioration under climate change is often overlooked in climate risk assessments. Here we review how climate change influences river water quality via persistent, gradual shifts and episodic, intense extreme events. Although distinct in magnitude, intensity and duration, these changes modulate the structure and hydro-biogeochemical processes on land and in rivers, hence reshaping land–river connectivity and the quality of river waters. To advance understanding of and forecasting capabilities for water quality in future climates, it is essential to perceive land and rivers as interconnected systems. It is also vital to prioritize research under climate extremes, where the dynamics of water quality often challenge existing theories and models and call for shifts in conceptual paradigms.
