浙江天童国家森林公园常绿阔叶林主要组成树种材积与生物量相关关系探讨

Study on the correlation between volume and biomass of main tree species in the evergreen broad-leaved forest of Tiantong National Forest Park,Zhejiang Province

以天童国家森林公园常绿阔叶林主要组成树种为研究对象,通过测定其各组分生物量,建立了实测生物量与材积之间的回归模型,结果表明:主要组成树种各组分生物量与其材积之间存在着密切的相关关系,各主要树种材积与生物量的回归模型存在差异;回归方程精度较高,用于根据地区常绿阔叶林主要树种材积推算其生物量是可行的。

Based on the every organ biomass and volume measurement of main tree species in evergreen broad-leaved forest, Tiantong National Forest Park, Zhejiang province, the regressive models were established between the volume and biomass. The results indicated that there was close correlation among each biomass and its corresponding volume, but variable in the regressive models between the volume and biomass of each main tree species. The regressive equations had remarkable precision available for using biomass to predict biomass of main tree species in this area.
