摘　要：我國(guó)正在實(shí)施林業(yè)分類(lèi)經(jīng)營(yíng)，其主要內(nèi)容之一是森林資源林種結(jié)構(gòu)調(diào)整.該文根據(jù)森林可持續(xù)經(jīng)營(yíng)的森林資源結(jié)構(gòu)調(diào)整原則和森林分類(lèi)經(jīng)營(yíng)技術(shù)指標(biāo)，結(jié)合承德縣五道河林場(chǎng)的實(shí)際情況，調(diào)整了五道河林場(chǎng)的森林資源結(jié)構(gòu)，商品林的比重由原來(lái)的99%，下降到61%和25%，森林資源結(jié)構(gòu)調(diào)整后能明顯提高對(duì)立地條件要求較高的樹(shù)種的單位面積蓄積量.

Abstract：Forestry classification management is implementing in China now. Category of forest structure adjustment is a main task. Based on the principles of forest resources structure adjustment and technical index of forest classification, forest resources structure of Wudaohe Forest Farm is adjusted with its concrete condition. Commercial forest area is adjusted from 99% to 61% or 25%. Stand volume per hectare of some species which require better site quality increases after adjustment.
Keywords：forest function classification, forest resources structure adjustment, commercial forest, public beneficial forest
