在对我国桉树、落叶松及樟子松主要栽培区进行实地调查的基础上 ,利用有关地区森林资源二类调查及样地测定资料 ,以气候生产力为指标 ,比较评价了广东和海南桉树人工林、广西桉树人工丰产林和黑龙江省国有林区落叶松、樟子松人工林现实生产力。结果表明 ,广东粤西、海南省桉树人工林现实生产力分别是当地气候生产力的 2 2 .81%和 4 1.0 8% ;广西速丰林平均达73.78%。落叶松、樟子松分别达当地气候生产力的 2 5 .70 %～ 4 1.6 8%和 2 8.4 5 %～ 5 1.5 5 %。以典型局、场或丰产林项目为基础 ,对各研究树种人工林生产潜力进行了系统分析 ,提出在现有技术与经济条件下 ,桉树人工速丰林应达到气候生产力的 80 .0 0 %以上 ;落叶松在≥ 14指数、樟子松在≥12指数立地上的生产力应分别达气候生产力的 70 %和 80 %以上。
Based on the field survey of main cultivated areas of eucalyptus, larch and Pinus sylvestris var. Mongolica in our country, using the second type of forest resources survey and sampling data in the area, taking climate productivity as index, the eucalypt plantations in Guangdong and Hainan were compared and evaluated , Artificial eucalyptus plantations in Guangxi and Larch and Pinus sylvestris var. Mongolica plantations in the state-owned forest areas of Heilongjiang Province. The results showed that the actual productivity of eucalyptus plantations in western Guangdong and Hainan Provinces was respectively 22.81% and 41.8% of the local climate productivity and that of Suifenglin in Guangxi was 73.78%. Larix gmelinii and Pinus sylvestris var. Mongolica reached 25-70% -4.68% and 2 8.45% -5.55% of the local climate productivity, respectively. Based on the typical bureau, field or high-yield forest project, systematic analysis was made on the potential productivity of plantations of various tree species. It was suggested that under the current technical and economic conditions, artificial fast forest of eucalyptus should reach 80.0% of climatic productivity, Above; Larix sylvatica ≥ 14 index, Pinus sylvestris in the ≥ 12 index site productivity should reach respectively 70% and 80% of climate productivity.
