摘　　要：基于ArcGIS及InVEST模型计算吉林省西部地区碳储量,以其评估单元为植被覆盖类型,计算地上部分碳、地下部分碳、土壤碳、死亡有机碳四种基本碳库。对比不同年份,即2000-2020年吉林省西部地区碳储量时间变化与空间变化特征,通过对吉林省西部地区碳储量的集中程度、变化程度和变化趋势的分析,以及该变化与西部地区生态环境变化之间的联系,总结变化原因。结果表明:从整体上看,白城地区碳储量有所增长,松原地区有所下降;从各个县、市上看,大安市2020年碳储量增加幅度最大,而松原市减少幅度最大。Based on the ArcGIS and InVEST models,the carbon storage in the western region of Jilin Province is calculated.The evaluation units are vegetation cover types,and four basic carbon pools are calculated:aboveground carbon,belowground carbon,soil carbon,and dead organic carbon.By comparing the temporal and spatial characteristics of carbon storage in the western region of Jilin Province from 2000 to 2020,the concentra-tion,degree of change,and trend of carbon storage,as well as the relationship between this change and the eco-logical environment change in the western region are analyzed and the reasons for the change are summarized.O-verall,the carbon storage in Baicheng has increased,while in Songyuan it has decreased.At the county and city level,Da'an City has shown the greatest increase in carbon storage in 2020,while Songyuan City has shown the greatest decrease.
