摘要
对397株杉木人工林平均木立木蓄积经4种计算方法的计算结果进行分析,表明不同方法计算的蓄积均有显著差异。在采伐作业设计和伐后验收的蓄积计算上应采用相同的计算方法或编制区域性根径一元材积表,以减少误差。
After analyzing the results from 397 mean sampletrees＇ cumulation using 4 different methods of calculation,it is stated that there are remarkable differences among these results from different methods.ln the fell task design and cumulation calculation,the same calculation method should be taken and a one way volume table with regionality should be workouted so as to reduce the errors.
