| 摘 要： | 以千烟洲生态试验站人工林内几种主要灌木为研究对象，采用EXCEL统计软件分析模拟了灌木的测树因子：高度，地径，冠幅两两之间存在的相关性方程，同时也分析模拟了枝条、树叶、根以及总生物量之间存在相关性方程。研究结果表明：所建立的方程判断系数R^2都比较高，方程具有一定的适用性，通过实验建立的方程可由一个变量推算另一个变量，这对于灌木生物量的调查具有重要的意义。为今后林下植被的生长提供了保护，为清查千烟洲地区森林生物量提供一定的依据。 |

| Abstract: | This study took the typical shrubs selected from the planted forests in Qianyanzhou as the objects. The software Excel was used to analyze the pertinence of the diameter, height and crown of the shrub plants and that of the branches, leaves roots and the total biomass. Based on the analysis two regressive models of the measure factors were established. The result showed that the estimate coefficients - R^2 were high and the models had certain adaptability. The models could be used to calculate one variable from another variable, which is significant for investigation of the biomass of shrubs. This study offers theoretic basis for the protection of the under- forest vegetation and the investigation of the biomass of the forests in Qianyanzhou. |
