Modern Forest Science, Forest and Forestry

This paper expounds the development and variation of forest science, forest and forestry nearly in past two centuries. The forest science in itself goes through a transformation from traditional forest science to modern forest Science. The modern forest science with the object of studying the establishment, management and utilization of forest ecosystem and the core of developing the ecological environment function of forest ecosystem, is a subject that takes an overall play to the multiple benefits and functions of forest. The cognition of forest also undergoes a variation from a single tree to tree group and still to forest ecosystem. Due to the deep alteration of the understanding of forest science and forest, people begin changing their understanding of forestry from a central form of timber utilizing which formed for a long time to a form that takes developing the ecological environment function of forestry ecosystem as its core and focal point, and takes an overall play to the ecological, economical and social function of forestry as its leading thought and aim, so as to realize the sustainable forestry development.
