黄河主要支流水沙量占黄河上中游总水沙量比例时间序列图（1955-2015年）

数据为黄河主要支流水沙量占黄河上中游总水沙量比例时间序列图（1955-2015年），时间范围是1955-2015年，将支流水文站水沙量分别除以同年黄河上中游总水沙量，以这个比例为纵坐标，以时间为横坐标。数据集包括洮河、湟水、祖厉河等29条主要一级支流出口水站和湟水支流大通河享堂站、渭河支流北洛河 头站、泾河张家山站共32个水文站年径流量和年输沙量随时间变化的64幅图，此类图反映该支流产水产沙量对黄河上中游总水沙量的贡献随时间的变化情况。数据集来自刘宝元等编著由科学出版社出版的《黄河水沙时空图谱》（第二版）。此数据可供水文、水利、水土保持、生态、环境、农业、国土整治等有关研究、教学、和各级管理人员参考。

The dataset consists of time series plots (1955-2015) illustrating the proportion of water and sediment load from major tributaries of the Yellow River relative to the total water and sediment load of the upper and middle reaches of the Yellow River. The time span covers 1955 to 2015. For each hydrological station on the tributaries, the measured water and sediment load is divided by the total water and sediment load of the upper and middle Yellow River in the same year, with this proportion as the vertical axis and time as the horizontal axis. The dataset includes 64 plots depicting annual runoff and annual sediment load changes over time for 32 hydrological stations: 29 outlet stations of major first-order tributaries such as the Tao River, Huangshui River, Zuli River, plus three additional stations including Xiangtang Station of the Datong River (a tributary of the Huangshui River), Toutou Station of the Beiluo River (a tributary of the Wei River), and Zhangjiashan Station of the Jing River. These plots reflect the temporal variations in the contribution of each tributary's runoff and sediment yield to the total water and sediment load of the upper and middle reaches of the Yellow River. The dataset is sourced from *Spatial and Temporal Atlas of Water and Sediment in the Yellow River (Second Edition)*, compiled by Liu Baoyuan et al. and published by Science Press. This dataset can serve as a reference for relevant research, teaching, and managers at all levels in the fields of hydrology, water conservancy, soil and water conservation, ecology, environment, agriculture, and land consolidation.
