利用在不同立地条件、不同龄组林分中收集的562株湿地松样木，采用现代建模技术拟合湖南省湿地松地征二元立木材积估测模型，研制出了湖南省湿地松地径二元立木材积表，提供了用地径估测立木材积的方法。
Using 562 samples of Pinus elliottii collected in different stand sites and different age groups, modern modeling techniques were used to fit the estimation model of the two-component stand volume of Pinus elliottii in Hunan Province. Trail bivariate timber volume chart provides a way to estimate the lumber area with a bore diameter.
