摘要
选择帽儿山地区6种典型灌木暴马丁香(Syringa reticulatavar.amurensis)、刺五加(Acanthopanaxsen-ticosus)、鸡树条荚蒾(Viburnum sargentii)、乌苏里绣线菊(Spiraea ussuriensis)、毛榛(Corylus mandshurica)、卫矛(Eu-onymus alatus)进行地上生物量及其相关因子研究。以地径和植株高度为指标,通过数学模拟,建立并筛选出最优生物量回归方程。结果表明,6种典型灌木的最优生物量回归方程均为幂函数方程(R2=0.471～0.861,p<0.05);模型模拟结果良好(R<30%;R<20%),可以用于灌木地上生物量的估算。
An experiment was conducted to study the above-ground biomass of Syringa reticulata var.amurensis,Acanthopanax senticosus,Viburnum sargentii,Spiraea ussuriensis,Corylus mandshurica,Euonymus alatus in Maoershan area of Heilongjiang Province.The optimal regressive equation of above-ground biomass of the shrubs was established using ground diameter and plant height as the estimation indexes by mathematical simulation.Result showed that the biomass could be well expressed by an exponential function.The model can be used to estimate above-ground biomass of shrubs due to its better simulation result.
