根据新世纪我国林业跨越式发展的基本思路 ,按照抓好林业六大重点工程的总体布局 ,人们对人工商品林的培育、管理和经营都提出了更高的要求。南方杉木人工商品林产区目前的突出问题是 ,经营单位何时采伐利用可以获得最大的收获量、取得最好的经济效益。通过对杉木人工林生长规律的深入研究 ,建立不同立地质量等级杉木人工林生长与收获预测模型 ,揭示其不同年龄阶段的蓄积收获量、商品材 (木材 )收获量和经济 (货币 )收获量 ,进而以最大收获量为目标、科学地确定杉木人工林的最佳主伐期 ,为林业可持续发展和合理经营利用提供可靠的定量依据。
According to the basic idea of China’s forestry leapfrog development in the new century and according to the overall layout of the six key forestry projects, people have put forward higher requirements on the cultivation, management and operation of artificial forest products. At present, the prominent problem in the south China fir commercial forest products production area is when the operating units can harvest the maximum harvests to obtain the best economic benefits. Through the further research on the growth of Cunninghamia lanceolata plantation, the prediction models of growth and harvest of Cunninghamia lanceolata plantations in different habitats were established. The accumulation and harvesting of different ages, the harvest of commercial timber (timber) and the economic (monetary) In order to achieve the maximum harvest, scientifically determine the best main cutting period of Chinese fir plantations, and provide a reliable quantitative basis for sustainable development and rational management of forestry.
