2019-08-29 A dataset of water eight ions contents at stations of Chinese Ecosystems Research Network (CERN) during 2004-2016 doi:10.11922/sciencedb.862 en Water is an important component of nature and a major environmental factor in the ecosystem. Chinese Ecosystem Research Network (CERN) conducted long-term in situ monitoring for water environments in typical ecosystems. This dataset collected water chemistry monitoring data on the eight ions (Ca2+, Mg2+, Na+, K+, HCO3- , CO32- , SO42- , Cl-) in the ground water, still surface water and flowing surface water from 34 terrestrial ecological stations during 2004-2016. The data were observed at five typical terrestrial ecosystems in China: farmland, grassland, forest, desert and peatland. With the test for accuracy and the elimination of outliers, we improved the data in format and reliability. These data are helpful in understanding the characteristics of hydrochemical changes in various ecosystems. 地下水; 静止地表水; 流动地表水; 八大离子; 生态站 黄丽 张心昱 袁国富 朱治林 唐新斋 孙晓敏 PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset http://www.doi.org/10.11922/csdata.2019.0044.zh Science Data Bank
