摘要
通过外业调查白河林业局不同径级天然水曲柳胸径、树高的情况,用相关软件对数据进行整理和分析,研究白河林业局天然水曲柳的生长状况。研究结果表明,天然水曲柳多分布在10~52径级,不同径级的天然水曲柳在总体水平上差异性极显著,一元材积模型和二元材积模型的拟合度均很高,表明这两个模型均适合模拟白河林业局的天然水曲柳材积。
Through the field,investigation to master different diameter grade fraxinus manfraxinus DBH and tree height in Bai He Foresty Bureau,and related software to analyze data,we can draw forest natural growth conditions of fraxinus manfraxinus in Bai He Foresty Bureau,through the analysis of the data can be seen:natural fraxinus manfraxinus distribution at level 10~52 diameter,single factor analysis of variance showed that natural fraxinus mandshurica in the overall level of different diameter level difference is very significant,a volume model and the fit of the binary volume of the model are very high,show that these two models are suitable for simulation of the fraxinus manfraxinus Bai He foresty bureaul volume.
