Abstract: The Shelter Forest System Program in Three-North Region of China (the Three-North Shelter Forest Program) is the largest ecological reforestation/afforestation program in the world, and has made great achievements since it was initiated in 1978. With the development of the Program, its influence became larger and larger, but its English expression has not been unified and standardized, making the international exchange about the Program a good many inconvenience. Based on a wide range of literature collection on the Three-North Shelter Forest Program,  an English expression of the Program was suggested to discuss with the coteries, aimed to give help to the unification and standardization of the English expression for the Program.

Key words: Evergreen broadleaved forest, Biomass, Net primary productivity(NPP), Fine root, Leaf lifespan
