林分立木材积估计的新方法
A New Method to Estimate Tree Volume
【摘要】 利用相对树高曲线法建立杉木、马尾松的分树种和不分树种的模型,结合二元材积表估测林分和样地的立木蓄积,接近用二元材积表法估测立木蓄积的精度,比一元材积表法估测的精度有大幅度的提高
【Abstract】 The tree height models of Chinese fir and Masson pine have been established by species or not by species adopting comparative dominant tree height. The tree volume exists in stand or sample plot has been estimated by applying the established models together with standard volume table. It shows that the estimation precision is near to the pecision presented by standard volume table and is greatly improved comparing with the precision presented by local volume table.
