Abstract:
On the basis of multipurpose regional geochemical survey, ecological geochemistry is a complex project composed of ecogeochemical assessment, ecogeochemical evaluation, ecogeochemical warning and ecogeochemical remediation. This paper systematically summarizes the achievements in the research of ecogeochemistry in China for recent years. Progress in regional ecogeochemical assessment has been presented, including the research on river ecosystem in Yangzi regions, farm land ecosystem in Shanxi, urban ecosystem in Beijing, and those lakemarsh 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 ecogeochemistry have also been proposed in this article, as well as the depicting of the future of ecogeochemistry.
