| 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. |
