摘要：[目的]提升东北地区蒙古栎单木生物量及碳储量预估的精准度,为科学管理蒙古栎生长提供理论基础。[方法]通过收集黑龙江、吉林、辽宁地区及内蒙古东部地区共175株蒙古栎单木地上各器官生物量(其中地上生物量122株、全树生物量53株)、胸径、树高数据以及查阅发表的蒙古栎各器官碳含量数据,建立了蒙古栎地上和地下的一元、二元生物量及碳储量独立模型,采用非线性联立方程组建立了东北地区蒙古栎单木满足可加性的各器官一元、二元地上生物量、碳储量相容性模型和以代数和控制下的聚合型模型。采用根茎比模型建立了地下相容性生物量、碳储量模型。[结果]所建立的地上各器官及总地上生物量、碳储量模型Radj2在0.704 8~0.961 8,且其总体相对误差(TRE)均不超过±1%,平均预估误差(MPE)均小于10%,符合建模标准。地下生物量模型Radj2处于0.770 2~0.780 1之间,其TRE不超过1%, MPE均小于15%,符合建模标准。[结论]本文所建立的各模型精度均达到了建模标准,聚合型碳储量模型精度略高于各器官相容性模型,可为东北地区蒙古栎单木生物量预测提供参考。
[Objective]Improve the accuracy of biomass and carbon storage of Quercus mongolica in Northeast China and provide a theoretical basis for scientific management of Q.mongolica growth.[Meth-od]By collecting data on biomass of aboveground organs,DBH,and tree height from 175 Q.mongolica in-dividual trees in Heilongjiang,Jilin,Liaoning,and eastern Inner Mongolia(including above-ground bio-mass data from 122 trees and whole-tree biomass data from 53 trees),as well as published carbon con-tent data for Q.mongolica organs,independent univariate and bivariate models for above-ground and be-low-ground biomass and carbon storage of Q.mongolica were established.Nonlinear simultaneous equa-tions were used to establish compatible univariate and bivariate models for aboveground biomass and car-bon storage of individual organs in Q.mongolica ensuring additivity,and the aggregated model con-strained by the algebraic sum.Compatible models for below-ground biomass and carbon storage were es-tablished using the root-to-shoot ratio model.[Result]The R2adj of the aboveground organs and total aboveground biomass and carbon storage models ranged from 0.7048 to 0.9618,and the overall relative error(TRE)was less than±1%,and the mean prediction error(MPE)was less than 10%,which met the modeling criteria.The R2adj of the underground biomass model was between 0.7702 and 0.7801,with TRE less than 1%and MPE less than 15%,which met the modeling criteria.[Conclusion]The accuracy of all models established in this study met the modeling criteria.The aggregated carbon storage model showed slightly higher accuracy than the compatible organ models,and these models can provide refer-ences for biomass prediction of Q.mongolica individual trees in Northeast China.
