山东省森林碳储量计量方法的研究

Study on measure methods of forest organic carbon storage in Shandong Province

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,大大提高了估测精度,减少了系统误差项对拟合精度的影响,并以此利用山东省一类、二类森林资源调资料对山东省11个年度的森林碳储量、6个年度的各森林类型的碳密度进行了估算,估算精度达到了95%左右,并提出碳汇计量的发展方向。

In the fact of shandong province, with the studied achievement of Wang xiaoke and Fang Jingyun etc., and thesurvey data of shandong forest at different time from every continuous forest check, the forest output and density of the woodfrom Shangdong Province Science Academe. Based on forest resource inventory data, the organic carbon storage of forest in Shandong Province was estimated to be 107.68Tg , The actual forest carbon density is directly affected by human activities anddisturbances, if adjust to the theory of forest succession, with more intensive management, and more rainfall at even of timeand space, it was more increasing; and was decreasing or its increasing speed was lower otherwise. With sufficient biomass surveydata 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 periodsand forest type carbon storage density of 6 annual periods ,the estimated precision was arriving to 95% or so.In the last,proposed the improving direction of carbon storage Measure Methods .
