National Surface Water Chemical Dataset from the Beijing-Tianjin-Hebei Region (2009-2022)

This data set collates the physical and chemical data of 51 long-term conventional monitoring stations in the Beijing Tianjin Hebei National Field Station of the Ecological Environment Research Center of the Chinese Academy of Sciences from 2009 to 2022, including 20 physical and chemical indicators including pH, water temperature, conductivity, salinity, total phosphorus, phosphate, total nitrogen, ammonia nitrogen, nitrite, nitrate, fluoride ion, silicon, chemical oxygen demand, dissolved oxygen, dissolved total organic carbon, dissolved total inorganic carbon, dissolved total carbon, bacteria, Escherichia coli, chlorophyll, and 88277 values.

The compilation and publication of this dataset can provide a data foundation for exploring the characteristics of changes in Beijing's urban ecosystem, and provide scientific support for understanding the chemical changes in urban surface water.
