地表水水质水文数据

从生态环境部及省级生态环境厅，水利部及省级水利厅官网公开收录的地表水水质实时数据，每4小时更新一次；水文数据每天或者每小时一次，可以为涉水质、水文相关研究提供实时数据支撑。

This dataset comprises two categories of data publicly sourced from the official websites of the Ministry of Ecology and Environment (MEE), its provincial-level ecological environment departments, the Ministry of Water Resources (MWR), and their provincial-level water resources departments. Real-time surface water quality data within the dataset is updated every 4 hours, while hydrological data is updated either daily or hourly. Both types of data can offer real-time data support for research related to water quality and hydrology.
