摘要
以湖南国有林场主要用材树种杉木林为研究对象,利用ForStat(统计之林)软件上进行多元函数模拟和线性回归函数模拟。分别对本文采用的6种蓄积量模型进行数据分析,模拟结果的对比分析表明:模型M=aH^bN^c+a_1H^(b1)N^(c1)运用于湖南省国有林场杉木中龄林林分蓄积量研究时,其效果在6种模型中最佳,确定系数为0.8937,平均相对误差为13.4251%,精度为97.1948%,研究结果有利于湖南国有林场杉木人工林可持续经营。
Taking the main species of Chinese fir plantation in state-owned forest farms in Hunan as the research object,using ForStat software of multiple function simulation and linear regression function simulation.Analyzed the data of the six models used in this research, the simulation results of comparative analysis show that：M = aH^bN^c＋ a1 H^（b1） N^（c1） is the best model applied to this research,its sure coefficient is 0.8937,the average relative error is 13.4251%,the accuracy of 97.1948%. The research results are conducive to the sustainable management of Chinese fir plantations in state-owned forest farms in Hunan.
