Elm widely distributed in the temperate regions of the northern hemisphere, northwest China, north China, northeast, southwest, central China provinces are widely distributed. As the elm has strong adaptability, drought, cold, wind, resistance to a certain degree of salinity and infertility, developed, breed capacity 昜; tough material, can be used as tools, vehicles, bridges and other timber; Its leaves are excellent feed, so it is one of the best woods and tree species in northern China.
