摘　　要：根据闽北天然阔叶林资料,提出编制闽北天然阔叶林的新方法并建立相应材种的出材率模型。以林分平均胸径和平均树高为变量因子,采用联合估计法解决模型不兼容问题并利用免疫进化算法求解模型参数,研制了林分材种出材率模型。经检验,建立的出材率模型能很好地拟合实际情况,可在森林资源调查中推广应用。The data from the natural broad-leaved forests in the North Fujian were used to put forward the new method to establish the timber assortment model,Using the joint estimation method with immune evolutionary algorithm based on auxiliary factors of the diameter and height,the stand of volume ratio medal was constructed.Through test,the volume ratio medal can be fitted the actual situation,which could be popularized and applied in forest resource investigation.
