丰富的森林资源清查资料是了解各类森林材积准确信息的重要途径,如果能将这些资源用于估算森林生物量的动态变化,对于科学地指导森林的经营管理,特别是区域尺度的生物量模型验证,具有重要意义。本研究根据我国华北落叶松人工林的实际调查资料,综合分析后得到生物量相对生长方程、地上生物量与蓄积量之间有明显的线性关系、地上与地下生物量呈幂函数变化和根茎比与林分因子均没有显著性相关等结论。但由于本次所收集的华北落叶松人工林的数据基本属于幼中龄林,下一步应加大成熟林以及过熟林的研究工作,以便更好的预测和分析华北落叶松生物量的区域变化。
The abundance of forest inventory information is an important way to understand the accurate information of various types of forest products. If these resources can be used to estimate the dynamic changes of forest biomass, it is of great significance for the scientific management of forest management and management, especially the regional-scale biomass model Validation is of great importance. According to the actual survey data of Larix principis-rupprechtii plantations in our country, the relative growth equation of biomass was obtained after comprehensive analysis. There was a clear linear relationship between above-ground biomass and stock volume. The aboveground and underground biomass showed a power function change and rhizome-to-rhizome ratio No significant correlation with stand factor and other conclusions. However, since the data collected from this Larix principis-rupprechtii plantation basically belong to the young-middle-aged forest, the research work on mature and over-mature forests should be strengthened in the next step in order to better predict and analyze the biomass of Larix principis-rupprechtii Variety.
