三江平原丘陵区长白落叶松人工林立木材积表的编制

以三江平原丘陵区佳木斯市孟家岗林场的长白落叶松人工林为研究对象,进行根径（D0.0）、去皮胸径（D去）、树高（H）同胸径（D）关系的研究,结合解析木结果,建立一元和二元立木材积模型、根径立木材积模型和树皮材积模型。结果表明,长白落叶松胸径是根径的0.730 7倍,去皮胸径是带皮胸径的0.942 7倍,树高模型为H=121.0-13 754.9/（D＋116.6）;一元和二元立木材积（V）模型分别为V=0.000084738D2.7516和V=0.000 03D1.88737H1.19248,根径立木材积（V）模型为V=0.0002D0.022652;一元和二元树皮材积（V皮）模型分别为V皮=0.000051724D2.1911和V皮=0.000 059D2.311560H-0.163587。

Compilation on Volume Table of Larix olgensis Plantation in Hilly Area of Sanjiang Plain

Taking the Larix olgensis plantation of Kiamusze＇s Mengjiagang Forestry Farm in hilly area of Sanjiang plain as a research object,the relation between root diameter（D0.0）,inside bark diameter（D去）,tree height（H） and DBH（D） had been studied.The models of unary and binary stumpage volume,root diameter stumpage volume and bark volume were all established combining with the results of analytic standing trees.The results showed that the DBH of Larix olgensis was 0.730 7 times of its root diameter and the inside bark diameter was 0.942 7 times of its DBH.The tree height model was H=121.0-13 754.9/（D＋116.6）.The models of unary stumpage volume（V）,binary stumpage volume（V） and root diameter stumpage volume（V） were respectively V=0.000 084 738D2.751 6,V=0.000 03D1.887 37H1.192 48 and V=0.000 2D0.022 652.The unary and binary bark volume（V皮） models were V皮=0.000 051 724D2.191 1and V皮=0.000 059D2.311 560H-0.163 587.
