Influencing factors of ecosystem carbon storage in Jilin Province
Based on land use data from Jilin Province in 1990,2000,2010 and 2020,the InVEST model was used to estimate the ecosystem carbon storage in Jilin Province from 1990 to 2020,and a spatial Durbin model was established to explore the influencing factors of ecosystem carbon storage in Jilin Province and their regional differences.The results show that the trend of ecosystem carbon storage in Jilin Province initially increased and then declined from 1990 to 2020,with significantly positive spatial autocorrelation.The ecosystem carbon storage in Jilin Province is influenced by both natural factors such as climate and vegetation,as well as anthropogenic factors including economic development,urban construction and agriculture.The annual average NDVI and land surface human activity intensity are the most significant positive and the most significant negative impact factors,with influencing coefficients of 1.09 and-0.32,respectively.The ecosystem carbon storage in Jilin Province is affected by spatial factors,and neglecting spatial factors might lead to an overestimation of the impact of climate factors on ecosystem carbon storage in Jilin Province.Considering spatial factors,both the annual average NDVI and land surface human activity intensity exhibit positive spatial spillover effects,with influencing coefficients of 0.83 and 0.73.There exist regional heterogeneity in the main influencing factors of ecosystem carbon storage in the eastern,central and western part of Jilin Province.
