1985-2018年黄土丘陵沟壑区第三副区罗玉沟流域径流泥沙观测数据集

A dataset of runoff and sediment observations from Luoyugou watershed in the third sub-region of Loess Hilly-Gully Region(1985-2018)

径流泥沙是反映水土流失趋势、水沙变化的重要基础指标。黄河水利委员会天水水土保持科学试验站1954年在罗玉沟流域沟口布设径流泥沙观测站,本数据集为1985–2018年时段的罗玉沟口径流泥沙数据。该数据集是探索、研究黄土高原丘陵区第三副区水土流失规律的基础数据。依据测流断面的观测的水位、流速、含沙量3项指标,计算得到流量、径流量、径流模数、径流深、输沙量、侵蚀模数、单位面积径流量、单位面积冲刷量等数据,并经过对观测资料的整理、校对、复核、审查,整编形成包含实测流量、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径流泥沙成果数据集。本数据集为黄土丘陵沟壑区第三副区减水减沙效益研究、黄土高原地区水土保持科研、区域农业生产发展、黄河治理开发及水土保持规划设计等,提供了科学可靠、长期连续的数据支持。

Runoff and sediment is an important basic index that reflects the trend of soil and water loss and the change of water and sediment.In 1954,Tianshui Experimental Station on Soil and Water Conservation,Yellow River Conservancy Commission of the Ministry of Water Resources set up a runoff and sediment observation station at the gully of Luoyugou watershed in Tianshui city.It can be used as the basic data for exploring and studying the law of soil and water loss in the hilly area of Loess Plateau.Water level,flow rate and sediment concentration were measured by professionals through natural sections.The data of flow,runoff,runoff modulus,runoff depth,sediment transport,erosion modulus,runoff per unit area,washing per unit area and so on were obtained through calculation.It provides scientific,reliable and long-term data support for the benefit study of water and sediment reduction in the third sub-region of the Loess Hilly-Gully Region,scientific research on water and soil conservation in the Loess Plateau region,regional agricultural production development,Yellow River control and development and water and soil conservation planning and design.
