摘要
采用多元非线型回归模型建立了刺槐人工林林分平均直径、林分优势高、林分平均高、林分断面积、林分蓄积和林分经营密度的动态监测模型,所有模型的相对系统误差小于±2.8%,相对均方差小于4.9%。并根据生产实践需求,编制了刺槐人工林现实收获表,用于现实林经营质量的动态监测。
Using pluralisty nonlinear recursive model,to establise D,H_u,H_P,G,M,N management quality dynamic supervise mensuvated model of Robinia pseudoacacia.manpower forest.Relative economy error (C) of the models is less than ±2.8%.Relative mean square deviation (MSD) of the models is less than 4.9%,and to autharize real harvest table of Robinia pseudoacacia manpower forest,to use in dynamic supervise memsurated of real forest management quality.
