摘　　要：为摸清大冶市森林资源的碳储量及其碳汇潜力,并为今后的森林经营管理提供重要的数据依据,本研究利用2009年和2019年2次森林资源二类清查数据,对大冶市2009—2019年间的森林碳储量变化进行了估算,并依据林龄与碳储量之间的关系预测了2019—2060年的碳汇潜力。结果表明:2009—2019年间,大冶市森林植被碳储量总增长量为25.17×10^(4)tC,各乡镇森林植被碳储量的变化量差异较大,全市近半的碳储量增长集中在南部山区的乡镇,年均碳汇量达到9.23×10^(4)tCO_(2)/a,假设保持现有经营水平不变,大冶市森林植被碳储量在未来30年都还处于增长趋势,而2050年前后达到峰值,至2060年森林碳储量低于现有水平成为碳源。为提高大冶市森林碳汇能力,建议加强森林经营管理、推动林业碳汇产业发展,助力“双碳”目标的实现。In order to quantify forest carbon storage and carbon sink potential in Daye City,and provide important data basis for forest management in the future.In this study,the changes of forest carbon stocks in Daye City from 2009 to 2019 was estimated using the forest management inventory data in 2009 and 1019,and the carbon sink potential from 2019 to 2060 was predicted based on the relationship between forest age and carbon stocks.The results showed that from 2009 to 2019,the total increase of forest vegetation carbon storage in Daye City was 251700 tC,and the change of forest vegetation carbon storage varied greatly among townships.Nearly half of the increase of forest vegetation carbon storage was concentrated in the southern mountains of Daye,with an average annual carbon sink of 92300 tCO_(2)/a.Assuming that the current management level remains unchanged,the forest vegetation carbon storage in Daye City will continue to grow in the next 30 years,and will achieve the peak around 2050,then the forest maybe become a carbon source in 2060 because the carbon storage will be lower than the current level.For improving the capacity of forest carbon sequestration in Daye City,there suggested to strengthen forest management,promote the industry development of forestry carbon sinks,and achieve the goal of carbon peak and carbon neutrality at last.
