Abstract
Taking Fushun City as the research area,based on land use data from 2000,2005,2010,2015 and 2020,the carbon storage changes in the area were analyzed using ArcGIS software and InVEST model.The results showed that the area of arable land,forest and grassland had decreased from 2000 to 2020,while the area of water bodies,construction land and unused land had increased.The carbon reserves in Fushun City in 2000,2005,2010,2015,2020 were 1.327 3×108t,1.326 4×108t,1.312 9×108t,1.312 8×108t and 1.310 9×108t,respectively,showing a decreasing trend year by year,with a total decrease of 0.016 4×108t over the past 21 years.The carbon sequestration capacity of forest was the strongest,while that of unused land was the weakest.The decrease in forest and grassland area and the increase in construction land area were the main reasons for the decline in carbon storage in Fushun City in recent years.关键词
