日本鸟取大学的井上昭夫与黑川泰亨利用孔兹干曲线式推导出一种计算针叶树立木材积的理论二元材积公式V=1/[2(1-Hb/H)]1.060·π/4D2b·H[1,2]。本研究选取4个地区的1014株人工落叶松和樟子松为样本,以部颁二元材积公式的计算结果为参照,对该式进行适用性验证及评价。
Japan’s Tottori University of Japan Akio and Kurokawa Taiheng use Conzigan curve derived a calculation of softwood tree volume of the theoretical binary volume formula V = 1 / [2 (1-Hb / H)] 1.060 · π / 4D2b · H [1,2]. In this study, 1014 artificial Larix gmelinii and Pinus sylvestris var.mongolica were selected from four regions as samples, and the validation and evaluation of the applicability of the formula were based on the calculation results of the ministerial volume formula.
