| 为满足林政管理及理论研究需要,利用滇西北地区647株高山松编表样木数据,选用8种一元
材积回归方程,拟合各模型参数,建立了高山松材积与根径回归模型,并用检验样本215株进行了适用性
检验。结果表明,滇西北地区高山松材积与根径最佳模型为V= 7.730 919 × (1 - e-0.020 279×DR)3.753 409,相
关系数(R2)为0.91,总相对误差(RS)为-0.20%,符合森林资源调查精度要求。在此基础上,编制
了滇西北地区高山松根径立木材积表。 |
| 英文摘要: |
| In order to meet the needs of forest management and theoretical research, sample wood data
from 647 Pinus densata trees in northwest Yunnan were used and eight univariate volume regression equations
were selected to fit the model parameters and establish the regression model between volume and root
diameter of Pinus densata. Applicability tests were conducted on 215 test samples. The results showed that
the optimal model for the volume and root diameter of Pinus densata in northwest Yunnan was V=7.730 919
×(1 - e-0.020 279×DR)3.753 409, with a correlation coefficient (R2) of 0.91 and a total relative error(RS)
of -0.20%, which met the accuracy requirements of forest resource surveys. Based on the results, the
standing timber volume table of Pinus densata root diameter in northwest Yunnan was compiled. |
