碳汇,是指从大气中清除二氧化碳的过程、活动或机制。森林碳汇是森林植被通过光合作用将大气中的二氧化碳吸收并固定在植被与土壤当中,从而减少或降低大气中二氧化碳浓度的过程、活动或机制。在全球气候变化成为国际社会广泛关注的热点和焦点的今天,通过森林植被的恢复和保护增加林业碳汇以减缓和适应气候变化,正成为越来越重要的发展议题。 Carbon sinks refer to the processes, activities, or mechanisms that remove carbon dioxide from the atmosphere. Forest carbon sequestration is the process, activity or mechanism by which forest vegetation absorbs and fixes atmospheric carbon dioxide through photosynthesis to vegetation and soil to reduce or reduce the concentration of carbon dioxide in the atmosphere. Today, as global climate change has become a hot spot and focus of widespread concern of the international community, it is becoming an increasingly important development issue to increase forest carbon sequestration through forest vegetation restoration and protection to mitigate and adapt to climate change.
