摘　　要：以福建省内阔叶树为研究对象,通过收集基础数据,建立合理的数学模型,研制符合福建省林情阔叶树地径材积表。通过综合比较,从12个备选函数方程中筛选出最优定的阔叶树地径材积方程为幂函数方程:V=b_(1)×DD^(b_(2)),并在此基础上编制阔叶树地径材积表;经阔叶树地径材积方程的哑变量适用性和拟合精度双重检验,所选的阔叶树地径材积方程整体精度分别达到97.99%和98.96%,符合最优标准。说明以此建立的阔叶树地径材积表符合福建省客观实际,可为福建省省域范围内阔叶次生林典型植被的森林经营管护、案件调查工作提供科学依据。Through the double test of the dud variable applicability and fitting accuracy of the broad-leaved tree diameter pattern,the broad-leaved tree ground diameter-volume equation V=b_(1)×DD^(b_(2)).the highest accuracy and reliability,so the preparation of broad-leaved trees the ground diameter-volume sheet conforms to the actual forest situation in Fujian Province,and provides a scientific theoretical basis for the provincial forestry authorities to deal with the cases of broad-leaved tree logging,loss and broad-leaved tree accumulation logging disputes in the future,which can greatly reduce the cost of handling cases in field investigation of forestry systems and significantly improve the efficiency of similar dispute cases.
