摘要: 动态评估生态系统碳储量的影响,有助于揭示全球变化对生态系统碳循环的驱动机制,同时为生态系统综合管理提供决策参考。采用InVEST模型,结合森林资源清查资料(1992,2007,2012年)和生物碳实测数据,动态评估了四川省宝兴县生物碳储存状况。结果表明,过去20年宝兴县生态系统总生物碳密度呈现增加的趋势,从1992年的23.19t/hm2增加到2012年的50.68t/hm2。宝兴县1992,2007,2012年生物碳储量分别为724.57万t,1 327.36万t和1 582.94万t,年平均增长率为3.98%。可见,过去20年期间四川宝兴县的植被起到了强烈的碳汇作用。研究还发现,该县生物碳储量增加主要是由于有林地固碳量的增加引起,有林地生物碳储量分别为457.98万t,1 059.72万t和1 376.57万t。同时,1992—2012年宝兴县生物碳储量的高值区范围逐渐扩大,但其主要分布在中海拔山区的空间格局并没有改变。

Abstract: Dynamic assessment of ecosystem carbon storage can help reveal the drive mechanism of global change on ecosystem carbon cycle,and can also provide decision support for the integrated ecosystem management.In the present study,we adopted an Integrated Valuation of Environmental Services and Tradeoffs(InVEST)model,and combined the forest resources inventory data(1992,2007,2012)with the field investigated data to conduct a dynamic assessment of plant carbon storage in Baoxing County,Sichuan Province.Our result shows that the total carbon density increased from 23.19t/hm2 in 1992 to 50.68t/hm2 in 2012.The biological carbon storage in Baoxing ecosystem was 24.57×104t,1327.36×104t and 1582.94×104t in 1992,2007 and 2012,respectively,and annual growth rate was 3.98%.Our study suggests that over past twenty years vegetation in this area played a strong role in carbon sequestration,and the increase of plant carbon storage is mainly due to the increase of carbon sequestration in forestland,which were 457.98×104t,1059.72×104t and 1376.57×104t in these three years,respectively.Spatial distribution area with high carbon density is expanding during the past twenty years,which is still located in medium altitude mountainous areas.
