针叶速生丰产林资源潜力的研究

Studyon the Conifer Fast-growing and High-yeildingPlantations and Resource Capacity

在东丰县５个林场中选取红松和落叶松８２块标准地材料，分别进行这两个树种的“一般人工林”、“现实速生丰产林”和“部颁标准丰产林”三者之间的生长对比，说明了现实速生丰产林的优越性。通过计算立地因子得分值的方法，进行速生丰产林资源潜力预测，证明速生丰产林具有广阔的发展前景。

sample plots of larch and korean pine were investigated in 5 forest farms in Dongfengcounty.After″the common plantation″,″actual fast-growing and high-yeilding plantatioi″and″standardfast-growing and high-yeilding plantation″of these two species were contrastively studied,the advantagesof″actual fast-growing and high-yeilding plantation″were illustrated.The resotirce capacity was fore-casted by caculating the leading site factors scores,The economic benefits of fast-growing and high-yeild-ing plantations were studied at the same time.
