Abstract:

 On the basis of multipurpose regional geochemical survey, ecological geochemistry is a complex project composed of ecogeochemical assessment, ecogeochemical evaluation, ecogeochemical warning and ecogeochemical remediation. This paper systematically summarizes the achievements in the research of ecogeochemistry in China for recent years. Progress in regional ecogeochemical assessment has been presented, including the research on river ecosystem in Yangzi regions, farm land ecosystem in Shanxi, urban ecosystem in Beijing, and those lakemarsh ecosystems in Poyang Lake, Dongting Lake and Tai Lake. The methods of calculation of soil carbon reserves, soil baseline and background values, and the grading of soil pollution have been discussed on a regional scale. Further steps of the research on ecogeochemistry have also been proposed in this article, as well as the depicting of the future of ecogeochemistry.
