我国5种主要人工林乔木层碳储量生长模型及其气候驱动分析1
Growth Models and Its Climate-Driven Analysis of Carbon Storage in Tree Layers of Five Major Plantation Types in China
[目的]研建我国 5 种主要人工林(杉木林、杨树林、桉树林、落叶松林、马尾松林)的乔木层碳储量生长模型,确定碳储量平均生长量最大时的林龄,分析固碳能力差异及其受气候因子的影响,为提升人工林碳汇能力和森林可持续经营决策提供科学依据。[方法]基于第九次全国森林资源清查8 520 块样地的碳储量数据,采用非线性加权回归方法和可变参数模型,建立 5 种主要人工林的乔木层碳储量生长模型,分析年均气温、年均降水量对模型参数的影响,并比较 5 种人工林乔木层固…查看全部>>
[Objective]Developing growth models of carbon storage in tree layers for five major plantation types in China,i.e.,Chinese fir,popular,eucalyptus,larch,and Masson pine,determining the stand age with maximum average carbon growth,and analyzing difference of and climate effect on carbon sequestration capacity would provide scientific basis for increasing carbon sequestration capacity of plantations and decision-making of sustainable forest management.[Method]B…查看全部>>
