| 摘 要： | 利用河南山区、平原６２个县（市、区）收集的１１５４株刺槐样木，编制出了河南刺槐根径二元、一元立木材积表。用回归方法筛选出了刺槐根径与胸径关系的最佳数学模型（Ｄ１．３＝ａ０＋ａ１Ｄｒ＋ａ２Ｄ２ｒ）。并根据模型提出由立木积材表导算根径立木材积表的方法。

| Abstract: | Based on 1 154 Robinia peseuaoacacia samples selected from the mountainous and plain areas of 62 counties in Henan prouince, stumpage volume table based on both diameter at stump level and measurements and univariate diameter at stump level are made. The optimum mathematical model of the relation of diameter at stump level and diameter breast high (D,B,H) was screened by means of regression method. The model is (D 1.3 = a 0+ a 1Dr+ a 2Dr 2) According to the mathematical model of the relation of diameter at stump level and D,B,H,the method of stumpage volume tablemaking based on diameter at stump level is put forward which is derived from volume table based on both D,B,H and measurements. |
