摘　　要：黄河水土保持绥德治理监督局(黄河水利委员会绥德水土保持科学试验站)(以下简称“绥德站”)1964年在黄土高原丘陵沟壑区第一副区陕西省绥德县韭园沟流域沟口布设径流泥沙观测站,观测韭园沟径流泥沙形成过程,观测数据覆盖1964–1969年与1974–2018年两个时段。依据测流断面观测的水位、流速和含沙量3项指标,通过计算获得流量、输沙量、洪水总量、洪水输沙量、单位面积径流量、径流系数、单位面积土壤侵蚀量、逐日平均流量、逐日平均含沙量、逐日平均悬移质输沙率等数据,经整理、校对、复校、审核后形成包含实测流量、洪水水位要素摘录、逐次洪水测验、逐日平均流量、逐日平均含沙量及逐日平均悬移质输沙表的整编数据。本数据集可为黄土丘陵沟壑区的水土流失规律研究和经过不同程度治理后的蓄水拦泥效益研究提供科学可靠和长期连续的数据支撑。In 1964,a runoff and sediment observation station was set up at the gully mouth of Jiuyuangou watershed in the first sub-region of Loess Hilly-Gully Region in Suide County,Shaanxi province by Suide Bureau of Yellow River Soil and Water Conservation and Supervision,also known as Suide Test Station of Water and Soil Conservation,Yellow River Conservancy Committee of the Ministry of Water Resources(“Suide Station”).The observation data covers two periods of time:from 1964 to 1969 and 1974 to 2018.Based on the three indexes of water level,velocity and sediment concentration observed in the measured section,the data was obtained,including discharge,sediment transport,total flood volume,sediment transport,runoff coefficient,soil erosion per unit area,daily average discharge,daily average sediment concentration and daily average suspended sediment transport rate.The sediment runoff dataset was created after collation,calibration,re-calibration and verification.This dataset provides scientific,reliable and long-term observation data for the study of soil erosion regularity in Loess Hilly-Gully Region and the benefit of water storage and sediment interception after different degrees of treatment.
