摘要
利用山东省各树种生物量调查资料,对原蓄积量与生物量之间的拟合方程参数进行了校正,提高了估测精度,并利用GM(1,1)模型对未来20a的山东省森林碳储量进行了预测,预测精度达到98%左右,2032年的碳水平可比2012年提高1.07倍;针对森林碳储量增速趋缓的态势,提出了6项技术对策,并提出灰色预测的适应范围和注意事项。
With sufficient biomass survey data of every tree species in shandong province,the old fitting equation parameters were revised between Volume and biomass,estimation accuracy would be more and more improved,the influence of fitting precision was decreased by System error.Then with the forest sources survey data of the first and the second sorts it was estimated forest carbon storage of 11 annual periods.With GM（1,1）model,discussed scientific prediction of forest carbon storage in Shandong province for the next 20 a,the prediction precision was as 98% or so,the C level in 2032 would be more 1.07 times than 2012.Confront situation hasten delay of forest carbon storage speed increase,6technical measures was discussed to advance with the times.In the last,proposed applicability and notices.
