White Birch, growing rapidly and having stronger adaptability to the environment, is quality species to regeneration forest culture for restitution vegetation and conservation of both water and soil, also a important economic tree species for medicinal and edible application. So there will a very extensive global development prospect for white birch resources. The progress in the aspect of geographical distribution, community ecology, growth and development, Reproductive Ecology transfer-gene breeding, the processing utilization of wood, sap and bark of white birch resources in China was documented in this paper. At the meantime, suggestion on possibility of forming white birch industry and developing a new substitute estate in the protection engineering of the nature forest in China was put for forward for implementation rational exploitation, utilization of birch resources of China.
