长江源水源涵养区隆宝滩水文观测数据（2007-2020）

长江源水源涵养区隆宝滩水文观测数据基于青海省长江源区典型水文断面连续14年的原位监测数据构建，系统记录月尺度径流量动态（单位：m³/s）。该数据集依托国家水文监测规范，采用超声波流速仪与水位-流量关系曲线法开展每日8次定时观测，通过数据清洗、异常值剔除及月均值整编形成高精度序列。作为青藏高原少有的长序列高寒径流实测资料，该数据集为SWAT、VIC等分布式水文模型参数率定提供关键验证基准，支撑积雪-冻土-径流互馈机制解析等研究。

The Longbaotan hydrological observation dataset in the water conservation area of the Yangtze River Source Region is constructed based on 14 consecutive years of in-situ monitoring data from typical hydrological sections in the Yangtze River Source Region of Qinghai Province. It systematically records the monthly-scale runoff dynamics (unit: m³/s). This dataset complies with national hydrological monitoring standards, carries out eight scheduled observations per day using ultrasonic flow meters and the stage-discharge rating curve method, and generates a high-precision time series through data cleaning, outlier removal and monthly mean compilation. As one of the rare long-term in-situ alpine runoff observation datasets on the Qinghai-Tibet Plateau, this dataset provides key validation benchmarks for parameter calibration of distributed hydrological models such as SWAT and VIC, and supports research including the analysis of the mutual feedback mechanism between snow, frozen soil and runoff.
