福建桉树人工林材积表和蓄积量表编制的研究

Studies of the Volume Table and Stocking Table Compilations of Eucalyptus Plantations

通过对桉树人工林83块标准地和164株样木进行调查,选择V=aDbHc和V=aDb方程并进行多方程拟合对比,编制桉树人工林二元材积表和一元材积表,结果表明:该表可在森林调查中应用,且误差小,能满足林业生产上的精度要求。同时为提高林分蓄积量的测定效率,选择林分平均高和断面积为辅助变量,建立桉树人工林林分蓄积量预估模型,该模型经检验适用,可用于林业生产实践。

The results showed that the table could be applied in the forest investigation,meanwhile,the its error was small,it could meet the precision demand in the forestry production.meanwhile,in order to increase the determination efficiency,the eucalyptus plantation standing stocking pre-evaluation model was built with selecting the average standing height and basal area as the assistant variables,the model was suitable by the test,and could be applied in the forest productive practice.
