东北过伐林区主要森林类型林分蓄积量生长模型

Volume growth models of main forest types in over-logged forest region,Northeast China

以吉林省汪清林业局金沟岭林场的主要森林类型为对象,基于小班调查数据,利用R ichards、Logistic、单分子、Gompertz和Korf 5种理论生长方程,建立了林分蓄积量生长模型,采用模型拟合统计量、误差及残差分布对模型进行评价和检验。结果表明:白桦林、人工混交林、天然针阔混交林用R ichards模型最好,人工落叶松林、阔叶混交林、天然针叶混交林用Logistic模型最好。研究结果为该地区森林生长预测和经营优化提供了参考和依据。

Sub-compartment inventory data were used for the model calibration of volume growth of main forest types in Jingouling forest farm,Wangqing,Jilin.Richards,logistic,single molecule,Gompertz,and Korf growth equations were tested and fitting statistics,errors and residual distribution were reported.The results showed that the Richards model was the best volume growth model for birch forest,mixed forest plantation and nature conifer-broad-leaved mixed forest while the Logistic model was the best for larch plantation,broad-leaved mixed forest and nature coniferous mixed forest.These models provided the reference and basis for predicting forest growth in the region and forest planning.
