黄河水源涵养区主要水文站及控制流域分布数据

黄河流域水源涵养区由兰州以上的黄河源区、渭河南山支流流域和伊洛河流域三个区域组成，集水面积分别为22.25万km2、6.33万km2和1.86万km2。该区域以占黄河流域面积的38.3%贡献了全流域天然径流量的 84%，是黄河主要的产水区。本研究筛选了上述三个流域的出口水文站（兰州、咸阳和黑石关）；同时考虑到黄河源区面积较大，也选择了源头的黄河沿站和中段的唐乃亥站作为研究对象。

The water conservation areas of the Yellow River Basin consist of three regions: the source region of the Yellow River above Lanzhou, the tributary basins along the southern mountains of the Wei River, and the Yi-Luo River Basin, with respective catchment areas of 222,500 km², 63,300 km², and 18,600 km². This region accounts for merely 38.3% of the total area of the Yellow River Basin but contributes 84% of the basin’s natural runoff, making it the primary water-producing area of the Yellow River. In this study, we selected the outlet hydrological stations of the three aforementioned basins: Lanzhou Station, Xianyang Station, and Heishiguan Station. Given the large catchment area of the Yellow River source region, we also selected Huangheyan Station at the source and Tangnag Station in its middle section as research subjects.

背景概述

该数据集聚焦于黄河流域水源涵养区，涵盖黄河源区、渭河南山支流流域和伊洛河流域三个关键区域，提供了它们的集水面积和产水贡献数据。数据集筛选了兰州、咸阳、黑石关等主要水文站，并针对黄河源区增加了黄河沿站和唐乃亥站，以支持水文监测和分析。其特点在于突出了水源涵养区在黄河流域中的核心作用，以较小面积贡献大部分径流量，为水资源管理和研究提供基础数据支撑。
