大尺度森林碳预算的误差分析模型

 

(1)USDA森林清查和分析程序(FIA)中正在生长树干的当前体积的区域估算:

 

式中, 是当前正在生长树干的体积:下标分别表示个体和州;是适当的区域扩展因子。

 

(2)样本误差:

五个州区域的样本的总的体积差异:

 

 

式中,是州的州样本差异。

(3)回归误差:

扩展区域体积估算的预测差异():

 

式中,是对当前正在生长树干的体积的个体预测误差的变化,个体和州的扩展区域总的正在生长树干的体积的区域回归误差变化,可表达为

 

(4)测量误差:

由于扩展到整个研究区的正在生长树干的体积测量误差引起的差异为:

 

式中,是对于高度 H DBH(D) 的个体测量误差的差异。

 

(5)总误差:

考虑到所有误差源的全部区域正在生长树干的体积为:
