- Аннотация: Under the background of rapid global warming, the hydrological regime in the Arctic river basins, where permafrost is widely developed, has changed significantly. These changes not only altered the local ecological environment, but also had far-reaching impacts on the global climate system and socio-economy. Therefore, the study of hydrological processes in Arctic river basins has become a hot-spot issue at the forefront of the international scientific community. Based on a thorough review and critical analysis of domestic and international literature, this paper systematically summarizes the research findings and latest progress on the spatial and temporal changes of the runoff of major Arctic rivers, as well as the driving mechanisms behind these variations. In addition, the patterns and spatiotemporal differences in runoff changes between Eurasia and North America were analyzed in detail. Furthermore, the direct and indirect effects of precipitation changes (e.g., precipitation amount, rain/snowfall fractions) and permafrost degradation on Arctic runoff are thoroughly examined. Despite significant progress in data accumulation and scientific understanding in current Arctic hydrological research, considerable challenges persist, such as the scarcity of ground observations and the difficulty of quantitatively assessing the interactions among climate, snow/permafrost, and hydrological processes. Thus, establishing a robust observation network in the Arctic river basins and developing cold region hydrological models with account for the Arctic specifics are fundamental for gaining in-depth insights into the rapid changes occurring in the Arctic hydrological system. This is also crucial for addressing the risks of water-related disasters and enhancing water resource management in the Arctic region.Key words: Arctic amplification, hydrological regime, climate warming, permafrost degradation, net precipitation
