摘要
在全球气候变化背景下,实现碳达峰与碳中和是应对气候危机的重要举措,增汇减排作为其中的关键手段,如何高效估算森林碳汇成为目前研究的重点内容之一。文章依照“自下而上”与“自上而下”的划分思路,并以不同数据源为出发点,梳理总结了主要估算方法,构建当前森林碳汇估算方法分类体系;重点关注国产高分卫星数据在森林碳汇估算中的主要应用场景及适用性,探讨分析其优势与不足,以期为森林碳汇估算提供数据源选择思路和方法论参考。
In the context of global climate change,carbon peak and carbon neutrality are important measures to deal with the climate crisis.Increasing carbon sinks and reducing carbon emissions are the key measures.Accurate estimates of forest carbon sink is one of the core steps during the implementation of the measures.According to the differences in the approaches of“bottom-up”and“top-down”carbon sink evaluations,we reviewed the major forest carbon sink estimation methods based on data sources and constructed a framework for the classification of current methods.Also,we focused on the major scenarios and applicability of China s Gaofen satellites in forest carbon sink evaluation.We then discussed their advantages and deficiencies in order to provide reference for the determination of data sources and methodology for future forest carbon sink estimation in China.
