云南省“十三五”期间森林碳储量动态变化及碳汇潜力分析

Carbon sink potential analysis and dynamic changes of forest carbon storage in Yunnan Province during the 13th five-year plan period

采用云南省“十三五”期间森林资源监测成果数据,基于森林蓄积量换算因子法对云南省“十三五”期间森林碳储量动态变化和碳汇潜力研究分析,结果表明:云南“十三五”期间森林碳储量由21.9525亿t增加到23.9522亿t,森林碳储量净增加了1.9996亿t,年平均增量0.4999亿t。按假设单位面积蓄积目标法估算云南期未森林碳汇发展潜力,计算表明云南林业碳汇发展潜力巨大,“十四五”规划目标是可以实现的。

Based on the data of forest resources monitoring in Yunnan Province during the 13th five-year plan period,the dynamic changes of forest carbon storage and carbon sink potential in Yunnan Province during the 13th five-year plan period were analyzed by using the method of forest volume conversion factor,the results showed that the forest carbon storage increased from 2.19525 billion tonnes to 2.39522 billion tonnes,the net forest carbon storage increased by 1.9996 billion tonnes,and the annual average increment increased by 0.4999 billion t.The development potential of forestry carbon sinks in Yunnan Province is estimated by the assumed unit area accumulation target method.The calculation shows that the development potential of forestry carbon sinks in Yunnan Province is huge and the 14th five-year plan goal can be achieved.
