广东省林业碳汇解析及提升潜力分析

森林经营在增强二氧化碳吸收方面具有重要作用，在全球气候变化背景下，本文阐述了《联 合国气候变化框架公约》中我国的履约目标，并评估了 2005 年和 2010 年广东省土地利用变化和林业领 域的固碳量。结果显示广东省 2005 年森林生物量生长碳吸收合计总量为 47.02×109 kg 二氧化碳当量，乔 木林固碳占总固碳量的 88.87%，采伐消耗温室气体排放 11.47×109 kg 二氧化碳当量，采伐消耗温室气 体排放二氧化碳当量占总排放量的 76.12%。2010 年固碳量增长 11.68%，采伐消耗温室气体排放增加了 19.85%。通过对比分析，探讨了广东省林业碳汇的提升潜力及方向。

Analysis of Forest Carbon Sequestration and Its Promotion Potential in Guangdong Province

Forestry management plays an important role in enhancing carbon dioxide absorption. In this paper, the performance objectives of our country in (UNFCCC) under the background of global climate changes were introduced. The changes of greenhouse gases fixation and emission in the forestry field of Guangdong province were accurately analyzed by comparing the changes of land use and forestry greenhouse gases sequestration and emission in 2005 and 2010. The results showed that forest and other woody biomass carbon sequestration were 47.02×109 kg CO2 equivalence in 2005. The carbon sequestration of arboreal forest accounted for 88.87% of the total carbon sequestration. The emissions of carbon dioxide by cutting were 11.47×109 kg. The emissions of carbon dioxide by cutting accounted for 76.12% of the total emissions. Forest and other woody biomass carbon sequestration increased by 11.68% in 2010, while greenhouse gases emissions from cutting increased by 19.85%. Based on the comparison of forest resources between Guangdong province and otherprovince with similar geographical and climatic conditions, the potential of improving forest carbon sequestration in Guangdong province in the future was discussed.
