摘　　要：收集了辽宁省林业调查规划院30块一类清查固定样地数据资料,采用与距离无关的单木竞争指标,通过逐步回归的方法,建立了辽东栎天然次生林单木生长模型,方程为:ln (DGI) =1 4 2 2 2 89+1 2 0 2 4 4 8lnD -0 0 5 2 5 98DL - 0 0 0 0 36 6SDI,经检验预估效果良好。The data were collected from 30 fixed sample plots from continuous forest inventory of Forest Investigation Program Institute of Liaoning Province. Using distance-independent individual tree competition index by mean of step-regress,an individual tree growth model of Quercus liaotungensis natural secondary forest was constructed.The equation is ln(DGI)=1.422289+1.202448lnD- 0.052598DL -0.000366SDI.By testing the predicting effect of the growth model is very well.
