A Study on the Technique of Silviculture and Management of Fuelwood

During the period of the seventh five year plan,an experiment on the silviculture and management of dense plantation and extra-short rotation has been conducted in 26 experimental sites belonging to 13 experimental regions covering 5 natural ecological regions,12 Provinces of China.The density of fuelwood stand is 5 000～10 000 stems/hm2 generally,15 000～20 000 stems/hm2 in the southern coastal regions.The rotation is 1～2a,3～5 a in partial region of North China.The biomass yield of experimental forest are 3～5 times more than that of theordinary fuelwood stand,5～8t/(hm2·a)in northwest China experimental region,7～10t/(hm2·a)in northeast and North China,6～20t/(hm2·a)in Central China,10～20t/(hm2·a)in Southwest China, 20～25t/(hm2·a)in Southeast coastal region.At the same time,60 fine fuelwood species have been screened out from the traditional fuelwood species and native forest species all over China.
