摘　　要：以理查德方程为原型,采用哑变量的方式将林分调查因子生长的最大值作为立地质量的函数,构建以间隔期和立地质量等级为辅助变量的林分动态生长模型,运用混合蛙跳算法(SFLA)估计模型参数,并建立相容性林分出材率模型和林分平均木材价格模型,从而形成了福建柏人工林动态生长模型。文中探讨了该模型在森林资源林木资产评估中的应用,为森林经营经济效益最大化提供了有益的参考,有推广应用价值。Using the Richard equation for the prototype, with the method of dummy variable, the maximum growth of stand description factors was taken as a function of the site quality, and a stand growth model was built with plastochrone and site quality grades as auxiliary variables.Using shuffled flog leaping algorithm （ SFLA） to estimate the dynamic growth model parameters, and set up compatible stand outturn rate model and model of stand average timber price, a stand growth model for Fokienia hodginsii plantation was established.The application of this model in the forest resource assets assessment was explored, so as to offer a favorable reference for obtaining a maximum benefit of forest management and exhibited its value of popularization and application.
