黄河干流及主要支流水文站逐月平均流量数据集(1956-1990年)

黄河是我国第二大河流，该数据集是黄河流域水文站逐月平均流量数据，时间为1956-1990年，数据包括黄河干流水文站及主要支流主要水文站的149个水文站逐月平均流量、年径流量、年径流深度、年径流模数、年最大流量及发生时间、年最小流量及发生时间。数据集共分为黄河上游上段逐月平均流量数据、黄河上游下段逐月平均流量数据、黄河中游区上段逐月平均流量数据、黄河中游区下段逐月平均流量数据、黄河下游区逐月平均流量数据集5个数据实体。数据量纲为月、年平均流量：m3/s；年径流量：108m3；年径流深度：mm；年最大流量、最小流量：m3/s。数据是据中华人民共和国水利部水文局编印的各年的《黄河流域水文资料》中各年月年平均流量对照表整编得到。

The Yellow River is the second-longest river in China. This dataset contains monthly average flow data from hydrological stations across the Yellow River Basin, spanning the period from 1956 to 1990. It covers monthly average flow, annual runoff volume, annual runoff depth, annual runoff modulus, annual maximum flow and its occurrence time, as well as annual minimum flow and its occurrence time, from a total of 149 hydrological stations on both the main stream of the Yellow River and its major tributaries. This dataset is divided into five data entities: monthly average flow data of the upper segment of the upper Yellow River, monthly average flow data of the lower segment of the upper Yellow River, monthly average flow data of the upper segment of the middle Yellow River, monthly average flow data of the lower segment of the middle Yellow River, and monthly average flow data of the lower Yellow River. The units of measurement are as follows: monthly and annual average flow: m³/s; annual runoff volume: 10⁸ m³; annual runoff depth: mm; annual maximum flow and annual minimum flow: m³/s. This dataset was compiled based on the monthly and annual average flow comparison tables extracted from the annual "Hydrological Data of the Yellow River Basin" published by the Hydrological Bureau of the Ministry of Water Resources of the People's Republic of China.
