Ecogeochemistry is the scientific discipline that combines ecology and geochemistry. Ecogeochemistry involves in the studies of chemical, physical, geological and biological process and their interactions which control the ecosystem and its environment evolutions. In particular, ecogeochemistry is to describe and assess the state and development direction of ecosystem based on the study of the rule of chemical matters’ distribution, allocation, transportation and transformation in the ecosystem. Although the history of ecogeochemistry is relative short and scientists from western countries even seldom use the word “ecogeochemistry”, great progresses in this discipline have been achieved in the past decades. Several special ecogeochemistrical directions, such as urban ecogeochemistry, wetland ecogeochemistry and so on, has developed on the purpose of assessment of ecosystem safety and health, based on the ecogeochemistry mapping. Mountain is the major geomorphological unit and possesses the unique ecological characteristics. The ecogeochemistry in mountain region has not been systemically launched, although a large amount of achievements have been obtained in element geochemistry, biogeochemistry and ecogeochemical assessment. For the further work in ecogeochemistry in mountain region, more theoretical research should be propelled； meanwhile impeccable method system, research system and assessment system should be established.
