塞罕坝地区樟子松立木材积表研究
|
摘要
基于塞罕坝地区的实测数据建立了该地区樟子松人工林的二元材积模型、一元胸径立木材积模型和一元地径立木材积模型,分别为V=0.00006938D~(1.763)H~(1.037)(R~2=0.997)、V=0.000123D~(2.494)(R~2=0.970)和V=0.00001235D~(3.017)(R~2=0.950)。通过以上模型建立了该地区的二元立木材积表、一元胸径立木材积表和一元地径立木材积表。t检验表明,以上材积表在该地区有良好的适用性。该地区的二元立木材积模型与大兴安岭地区及辽宁地区的樟子松立木材积模型有明显差异,对于分布于不同地区的相同树种应分别建立不同的材积表。
Based on the data measured in the Saihanba area,standard volume model,one-way tree volume model of DBH and one-way tree volume model of ground diameter were established,which were V = 0.00006938D~(1.763)H~(1.037)(R~2= 0.997),V = 0.000123D~(2.494)(R~2= 0.970) and V = 0.00001235D~(3.017)(R~2=0.950),respectively.Based on the above models,the standard volume table,one-way tree volume table of DBH and one-way tree volume table of ground diameter are constructed.The t-test showed that the above volume tables had good applicability in the area.And there was a significant difference between the standard volume model in the Saihanba area and tree volume model of Scotch pine in Daxinganling and Liaoning areas.So different volume tables should be established for the same tree species distributed in different areas.
