摘要

摘要: 为了分析森林植被全口径碳汇能力及其在我国实现碳中和目标中的重要作用，本研究利用样地实测法，基于森林资源清查数据和中国森林生态系统定位观测研究网络的样地实测数据，测算辽宁省的森林植被全口径碳汇量。研究结果表明辽宁省森林植被全口径碳汇可以在全省实现碳中和目标中发挥重要作用：(1)第九次森林资源清查期间，辽宁省的森林植被全口径碳汇为1 233.92万t，乔木林植被层、其他森林植被层、森林土壤层分别贡献了71.78%、17.94%、10.28%，相当于中和了全省8.76%的能源消费碳排放量。(2)自第六次森林资源清查期以来，辽宁省的森林植被全口径碳汇呈现增加的趋势(增加了49.71%)。(3)各类林地单位面积固碳量均提升至乔木林水平的情况下，辽宁省森林全口径碳汇量将达到1 692.62万t，届时将抵消能源消费碳排放量的9.69%。

Abstract: In order to analyze the carbon sink capacity of forest vegetation and its effect for China to achieve the carbon neutral goals, the field measurement method of sample plots was used in this study based on the forest resource inventory data and the field measurement data of the China Forest Ecosystem Research Network to measure the forest vegetation full carbon sink of Liaoning Province. The results shows that the full carbon sink of the forest vegetation in Liaoning Province play important role in achieving carbon neutral goals: (1) The full carbon sink is 1 233.92×10⁴ t during the 9th period, with the contribution of each components of arbor forest vegetation layer (71.78%), other forest vegetation layer (17.94%), forest resource soil layer (10.28%), respectively, which is equivalent to neutralizing 8.76% of carbon emissions from energy consumption of the Liaoning Province. (2)Since the 6th national forest inventory, the full carbon sink of the Liaoning Province had shown an increasing trend, with an increase of 49.71%. (3)According to the carbon sequestration per unit area of arbor forest, the full carbon sink of forests in Liaoning Province will reach 1 692.62×10⁴ t, which will offset 9.69% of carbon emissions from energy consumption.

注：2004年，国家林业局发布的《“国家特别规定的灌木林地”的规定》中给出了特殊灌木林的定义，在随后的统计中一直沿用，作为灌木林的一种类型，其面积与乔木林面积相加是森林面积。
