The stemflow is an important research contents in the forest hydrology research. Research method and main conclusion of stemflow were reviewed based on the development of stemflow studies at home and abroad. The methods of stemflow studies were divided into practical measurement in field and calculation by mathematic model

and were respectively classified systemically and reviewed in brief. It was emphasized that the methods of measure in field have two critical techniques

including selection of sample trees and collection of stemflow. Stemflow mathematic models were divided into three kinds

which are experiential model

conceptual model and theoretical model

and their merits and flaws were pointed out. Experiential models reflected the quantitative relationship of stemflow quantity (or stemflow ratio) and rainfall

conceptual models described the quantitative relation between stemflow quantity and rainfall as well as forest characteristics

and theoretical models depicted the dynamic course of stemflow following rainfall.
