摘要
以长岭岗林场21,22a生两块日本落叶松人工林作研究对象,用3次间伐和皆伐获得的木材经济效益为依据,计算得出南方高山地区营造的日本落叶松人工林中小径材的经营初步效益,22a生日本落叶松人工林从间伐到皆伐的效益达到5.31万元/hm2,投入产出比为1.00∶98.30;21a生日本落叶松人工林从间伐到皆伐的效益达到4.65万元/hm2,投入产出比为1.00:37.79。探讨分析了南方高山地区营造的日本落叶松人工林中小径材的经济效益,为南方高山地区经营日本落叶松中小径材提供参考依据。
the 21-year,22-year old of two plots plantation for larix kaemferi （Lamb.）carr. in Changlinggang forest farm were studied on basis of three times thinning and clear cutting were got economic effect. The preliminary management effect of small- medium diameter pantation for larix kaemferi （Lamb.） carl in southern high mountainous area was calculated. The effect of 22-year old Plantation for larix kaemferi （Lamb.） carr. from thinning to clear cutting achieved fifty-three thousand yuan per ha. The input-output Pro- portion was 1.00.98.30 ;The effect of 21-year old Plantation for larix kaemferi （Lamb.）earr. from thinning to clear cutting achieved fourty-six thousand yuan per ha. The input-output Proportion was 1.00 ： 37.79. In order to provide reference base on small ~medium diameter plantation for larix kaemferi （Lamb.） cart. in southern high mountainous. The economic effect of small-medium diameter Plantation for larix kaernferi （Lamb.）cart. in southern high mountainous was explored and analyzed.
