本文受单株立木材积测定方法──望高法、形点法、胸高形率法和绝对形率法的启发，提出了形点法测定单株立木材积的方法，该方法测点较低、较合理，故量测时较前述四种方法容易。并用９９株落叶松解析木，对上述五种方法进行了精度检验。结果表明，用形点法测定落叶松单株立木材积精度最高，为测定落叶松单株立木材积提出了理论依据。
In this paper, a method of determining the standing timber volume per plant by the spot-point method is proposed based on the method of determining the stand volume of individual plants ─ ─ Wang Gao Fa, Xing Dian Fa, thoracic high form ratio method and absolute form ratio method. The method has the advantages of low measuring point, More reasonable, so the measurement of the above four methods easier. 99 trees of Larch were used to analyze the accuracy of the above five methods. The results showed that the precision of standing volume of larch was the highest by using the spot-point method, which provided the theoretical basis for measuring the standing volume of larch.
