摘要:

森林碳储量计量是在全球气候变暖背景下,实现“碳达峰”和“碳中和”目标的重要技术环节之一。目前常规的森林碳储量计量方法仍然主要采用传统的林业样地调查法,存在效率低、人力物力成本高,且对森林冠层数据的测定精度不高等问题。以无人机倾斜摄影测量技术在广西桉树冠层碳储量计量中的应用为研究对象,参考林业部门和各地的相关标准,采用实验对比和数理统计方法构建基于广西桉树冠层体积(V)推算其冠层碳储量(T)的计量模型。实验验证和回归分析方法测定该模型的拟合优度R2达到0.889 6。该模型可为广西桉树林碳储量的调查工作,以及其他树种的碳储量计量模型构建提供参考。

Abstract:

Calculating forest carbon storage is an important technology for China to achieve the goals of carbon dioxide peaking and carbon neutrality in the context of global warming.At present,conventional forest carbon storage accounting primarily adopts measuring standing trees in sample plots,which is less efficient and more costly in terms of labor.Meanwhile,there are problems such as the low accuracy of forest canopy data measurement.To address this issue,this study constructed a set of mathematical models based on the volume V of the canopy oblique photography model of Eucalyptus trees in Guangxi to predict their carbon storage T through experiments and data analysis.This was done using the oblique photogrammetry technology of unmanned aerial vehicles,as well as mathematical and statistical methods.Also,it takes reference to the relevant standards set by the forestry department and local authorities.It verified that experimental validation and regression analysis showed that the goodness-of-fit threshold R2 of this model reached 0.889 6,and the model can provide support for the investigation of eucalyptus forest carbon storagein Guangxi.At the same time,the methods and techniques in this study can also be appliedas a reference for constructing oblique photography carbon storage measurement models for other tree species.

Key words: carbon storage accounting, Eucalyptus canopy, UAV remote sensing, oblique photography, carbon sink modeling
