Modern Forestry Science,Forest and Forestry HE Qing-tang(Bejing Forestry
University,Beijing 100083,China) Abstract:This paper expounds the development and variation of the forestry
science,forest and forestry neally in past two cen turies.The forestry science
in itself goes through a transformation from traditional forestry science to
modern forestry s cience.The modern forestry science, with the object of
studying the establishment,manageme nt and exploitation of the forestry
ecosystem and the core of developing the eco logical environinent functi on of
the forestry ecosystem,is a subject that takes an overall play to the mul tiple
benefits and function of forest.The cognition of forest also undergoes a
variation from a single tree to trees g roup and still to forest ecosystem.Due
to the deep alteration of the understand ing of forestry science and
forest,people begin changing their understanding of forestry from a central for
m of timber utilizing which formed for a long time to a form that takes developi
ng the ecological environment function of forestry ecosystem as its core and fo
cal point,and takes an overall play to the ecological,economical and social
function of forestry as its leadi ng thought and aim,so as to realize the
sustainable development of forestry. |
