| 摘 要： | 在国家级森林资源监测中增加森林生物量估计已成为必然趋势,而地下生物量是森林生物量的重要组成部分.以东北落叶松和南方马尾松地下生物量数据为例,对地下生物量模型的两种常用建模方案进行对比分析,指出了存在的弊端,并提出通过利用度量误差模型,建立相容性地上、地下生物量模型和根茎比模型的方法.结果表明:利用度量误差模型方法,能有...

| Abstract: | It has become a trend to supplement national forest resources monitoring with forest biomass estimation.The below-ground biomass is an important component of forest biomass.Based on the belowground biomass data of larch (Larix spp.) in northeastern China and that of Masson pine (Pinus massoniana) in southern China,two approaches commonly used for modeling below-ground biomass,i.e.,below-ground biomass and root-shoot ratio equations,were compared,and problems in modeling below-ground biomass were addressed.T... |
