摘　　要：黄河水利委员会西峰水土保持科学试验站(以下简称“西峰站”)1975年在庆阳市宁县砚瓦川流域布设径流泥沙观测站,开展中尺度流域水土流失影响因子的长期定位观测。本数据集为该站1976–2018年径流泥沙观测数据,试验观测断面为大型抛物线型量水堰,观测方式为人工观测。数据集主要包括砚瓦川流域逐日流量数据、逐日平均含沙量数据、逐日平均输沙率数据、洪水水文要素摘录数据、逐次洪水测验成果数据。经整理、校核、复校和审核,形成径流泥沙整编数据。本数据集的建立为探索较大尺度流域的水土流失规律和水土保持措施蓄水拦沙效益提供了基础资料,同时为黄土高原水土流失综合治理和水土流失模型体系建立提供了基础数据支撑。In 1975,Xifeng experimental station on soil and water conservation(hereinafter referred to as"Xifeng station")set up a runoff and sediment observation station in Yanwachuan Watershed,Ningxian county,Qingyang city,to carry out long-term positioning observation on the factors that cause water and soil loss in mesoscale river basin.This dataset is a collection of runoff and sediment field data measured at Xifeng station from 1976 to 2018.The experimental observation section is a large parabolic water weir,and the observation method is manual observation.The dataset mainly includes the daily flow,daily average sediment concentration,daily average sediment transport rate,the data extracted from the hydrological elements of flood,and successive flood test results.After collating,checking,rechecking and auditing,the runoff and sediment consolidation data is produced.The establishment of this dataset provides the basic data for exploring the law of soil and water loss and the benefit of water and soil conservation measures in large river basins,and also provides the basic data support for the comprehensive management of soil and water loss and the establishment of soil and water loss model system on the loess plateau.
