Abstract: Water is an important component of nature and a major environmental factor in the ecosystem. Chinese Ecosystem Research Network (CERN) conducted long-term fix spot monitoring for water environments in typical ecosystems. This dataset collected water chemistry monitoring data from 33 terrestrial ecological stations during 2004-2016, the eight ions (Ca2+, Mg2+, Na+, K+, HCO3- , CO32- , SO42- , Cl-) of the ground water, still surface water and flowing surface water were analyzed. The data were observed at five typical terrestrial ecosystems of farmland, grassland, forest, desert and peatland in China. The dataset was tested for accuracy, and outliers were eliminated. The data format and reliability were improved. Hydrochemical status can be evaluated by using the data.
