摘要:黄河水利委员会天水水土保持科学试验站(以下简称“天水站”)1957年在桥子沟流域沟口布设径流泥沙观测站,1959年停测。1985年被黄委会列为对比试验典型小流域,1985年纳入罗玉沟流域雨量站网。1987年布设站网,在两条小流域出口处各设1处径流站,共设1个雨量站。流域内设3个群众委托雨量站和1个本站观测的试验场雨量站。本数据集包含1987-2018年包含桥子东、西沟沟口实测流量、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径流泥沙整编数据,由专业人员通过测流断面观测水位、流速和含沙量,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,再经整理、校对、复校、审核后形成。本数据集为黄土丘陵沟壑区第三副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观测数据。

Abstract & Keywords
Abstract: Qiaozigou basin observation station was set up for runoff and sediment observation by Tianshui Water and Soil Conservation Scientific Experimental Station of the Yellow River Conservancy Commission (hereinafter referred to as "Tianshui Station"). It began to work in 1957 and ended in 1959. In 1985, it was listed as a typical small watershed of comparative experiment by YRCC and incorporated in Luoyugou watershed rainfall observation network. In 1987, a network of stations was established. There are two sub-basins in Qiaozigou basin observation. Each of them One was set up a runoff observation station and shared one rainfall observation stations. In addition to this, there is one rainfall station at each outlet, three mass-commissioned stations and one experimental station in two small watersheds. This data set includes data between 1987 to 2018, which are calculated by professionals through the observation of water level, velocity and sediment content in the flow measurement section, 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. After collation, calibration, re-calibration and verification, runoff is formed. This data set provides scientific, reliable and long-term continuous observation data for the study of Soil Erosion Regularity in the third sub-region of Loess Hilly and gully region and the benefit of water storage and sediment interception after different degrees of treatment.
