Fine root productivity plays an important role in ecosystem carbon balance in forests.However,our understanding of the belowground of forest is relatively insufficient because of the limitation of technical method.Based on the data collected from the literatures,we reviewed the definition and classification of root,three main methods (soil coring,in growth core,and minirhizotron) used in root studies,temporal and spatial characteristics of root productivity,and major abiotic and biotic factors that affect root productivity.Finally,we discussed the problems arising in root research and proposed the research direction in future,aiming to provide Chinese researchers with references for forest root studies in China.
