Abstract:

Based on geochemical survey,eco-geochemistry assessment focuses on the circling of the elements in the ecosystems. And also,it investigates the input and output fluxes of soil elements,compounds,and other geochemical variables in order to predict the trend of their circling and make early-warning of risks. During the recent decade,the theoretical frame and the related techniques are under development with the emergence of a lot of technical standards,published articles and books. Furthermore,social and economic benefits have been produced in the aspects of pollution control,management of land resources,development of distinctive agricultural products,and even soil carbon sequestration and global warming prevention. Theoretical and practical requirements have pushed forward the development of eco-geochemistry and its branches have been developed in the areas of soil carbon sequestration,soil heavy metal from “high background”,geochemical assessment of land quality,development of soil beneficial element,and soil pollution control and remediation. This paper aims to summarize the progress of eco-geochemistry in China during the past decade.

Key words: multi-purpose regional geochemical survey, eco-geochemical assessment, geochemical assessment of land quality, forecast and early warning of ecological risks
