| 摘 要： | 以冀西北山区华北落叶松人工林为研究对象,分析了其材积的变化和生物量的分配规律,建立了树干材积和生物量之间的回归模型,结果表明:随着树木的生长,树高达到一定高度后,树高生长减缓,材积的年平均增长量呈增加趋势;各器官生物量分配从大到小依次为干>根>枝>叶,随林龄的增加都呈增加趋势;树干生物量与其材积之间存在着密切的相关关系,回归方程精度高,可用于该地区华北落叶松的生物量和材积的换算。 |
| 关 键 词： | 华北落叶松 材积 生物量 冀西北山地 |

| Abstract: | Based on the the volume and biomass distribution of the Larixprincipis-rupprechtii Plantations,the regressive models were established between the trunks volume and biomass.The results indicated that along with the growth of the trees,when the trees reach a certain height,high growth slowed and the average annual volume growth increased;The biomass of organs is in descending order of trunk>roots >branches >leaves,which presents an increasing trend with the increase of the age.There was close correlation between trunk biomass and its corresponding volume and the regressive equations had remarkable precision available for conversion between biomass and volume of the Larixprincipis-rupprechtii plantations. |
| Keywords: | Larix principis-rupprechtii volume biomass mountains in northwest Hebei |
