摘要
应用生理森林过程生长模型(3-PG)对杉木试验林的生长进行模拟,选择胸径、树高、干生物量和蓄积量的连年生长量等4个指标,对模型模拟值和实测值进行比较分析。结果表明,模型模拟值与实测值呈极显著的正相关关系(P<0.001),模拟值能解释观测值90%以上的变化;模型模拟的平均精度在85%以上。
The forest proceed based model（3-PG） was applied to estimate the stand growth of Chinese fir plantations at the experimental plots of subtropical forest experimental center,Chinese Academy of Forestry.The simulated results of DBH,tree height,stem biomass and stand volume were then compared with the corresponding observed values.The significant positive correlations were found between the simulations and observations（P0.001）,where the simulated values could explain above 90% variation of the observed.The model was proved with high accuracy and reliability to act as an useful tool for the management of Chinese fir plantation.
