| 摘 要： | 该文采用超总体理论编制辽宁省东部地区主要树种组林分平均胸径生长率通用模型，以2005年森林资源二类调查资料为原始数据，涵盖辽宁东部7个市31个县（市、区）8个树种（组）在不同地理位置和不同立地条件的生长水平。建立4种模拟方程，通过拟合与优化及结果精度的检验选出了各树种组的平均胸径生长率模型。

| Abstract: | In this research,the surpassing collectivity theory was adopted to compile the growth rate model of the forest stand average breast diameter of the main tree groups in east area of Liaoning province;and based on the results of the second class investigation of forestry resources in 2005,the model covered growth levels of eight tree groups in different location and site environment of seven cities and thirty-one counties in east area of Liaoning province.It constructed four simulative formulas,and the growth rate model of the forest stand average breast diameter of every tree group was selected through fitting,optimization and result accuracy check. |
