摘要
利用在全省福建柏人工栽培区和自然分布区的387块标准地和89株平均木树干解析材料,选择Korf理论生长方程,以优势木胸径为比较基础的相对直径作为单木竞争指标,采用生长量修正法建立单木直径生长量模型。经检验,该模型精度较高,可用于模拟福建柏生长动态。
The materials obtained from 387 standard plots and trunk analyzed from 89 average wood,which distribute in Fokiertia hodginsii plantation and forest in Fujian province.In this paper,the Korf theory growth equation was applied,just as correctional methods of growth volume,the growth volume model of single wood diameter,adopted relative diameter based on dominant wood as competitive index of single wood,was established and tested,it was proved to be precise highly and adapted widely to simulating the growing trends of Fokienia hodginsii.
