【摘要】 本文对红松材积因子与各生长性状的相关性进行分析后认为,用枝下高代替树高进行红松单株材积的二元方程回归是可行的。本文建立的材积二元回归方程具有测量方便、精度高的特点,可以在红松人工林测量中推广应用。更多还原

【Abstract】 This paper analyzed the correlation analysis of volume associated with growth traits of P. koraiensis. The results showed that the two element regression equation of tree volume using branch height instead of tree was feasible. The volume of the two element regression equation has the characteristics of convenient measurement,high precision,can be applied in the measurement of P. koraiensis plantation.更多还原
