中国河流范围图（CRED）（2016-2023年）

河流在生态多样性、航运贸易和碳循环中扮演着重要角色。近几十年来，受人类活动干扰和极端气候影响，河流范围频繁发生剧烈变化。迫切需要开发时序化、精细尺度的河流范围数据集，为河流保护、管理和可持续利用提供坚实数据支撑。文献综述表明，中国目前普遍缺乏空间分辨率较高的年度河流范围数据集。针对此...

Rivers play a critical role in ecological diversity, shipping trade, and the carbon cycle. In recent decades, affected by human disturbances and extreme climate events, the extent of rivers has undergone frequent and drastic changes. There is an urgent need to develop temporal, high-resolution river extent datasets to provide solid data support for river conservation, management and sustainable utilization. Literature reviews indicate that China currently generally lacks annual river extent datasets with relatively high spatial resolution. To address this
