Abstract: To develop the long-term localized observation and investigation on ecosystem flux is of great importance.On the basis of generalizing the concepts and connotations of ecosystem flux,this paper introduced the construction and development histories of Global Flux Networks,Regional Flux Networks (Ameri-Flux,Euro-Flux and Asia-Flux)and China-Flux,as well as the main methodologies,including micrometeorological methods (such as eddy correlation method,mass balance method,energy balance method and air dynamic method)and chamber methods (static and dynamic chamber methods),and their basic operation principles.The research achievements,approaches and advances of CO₂,N₂O,CH₄,and heat fluxes in forest ecosystem,farmland ecosystem,grassland ecosystem and water ecosystem were also summarized.In accordance with the realities and necessities of ecosystem flux research in China,some suggestions and prospects were put forward.

Key words: Ecosystem, Flux, Micrometeorological method, Chamber method
