伊犁地区陆地生态系统碳储量变化及影响因素
Carbon storage changes and influencing factors in terrestrial ecosystems of Ili region
摘要
Abstract
Changes in carbon storage are crucial for understanding terrestrial ecosystem dynamics.To investigate the changes in terrestrial ecosystem carbon storage,this study focused on the Ili region as the research area.Based on land use data from 2000 to 2020,the InVEST model was used to simulate the spatiotemporal characteristics of carbon storage in the study area.Geodetector and multiple regression residual analysis methods were employed to quantitatively analyze the driving factors affecting carbon storage and their contributions.The results indicate that:1)From 2000 to 2020,the annual average carbon storage in the Ili region decreased by 8.89 Tg,showing a spatial distribution trend decreasing from the southern and northern mountainous areas towards the central plains.2)The changes in carbon storage in the Ili region are affected by multiple factors,with elevation being the primary driving factor,having an explanatory power(q)of 0.469.The interaction between precipitation and the normalized difference vegetation index(NDVI)had the most significant impact on carbon storage.3)The contributions of climate change and human activities to the increase in carbon storage in the Ili region were 48.16%and 51.84%,respectively.Areas where climate change contributed more than 80%were mainly distributed in the southern and northern forest regions,while areas where human activities contributed more than 80%were concentrated in the central and eastern parts.In regions where carbon storage decreased,approximately 8.60%of the reduction was caused by the combined effects of climate change and human activities,primarily located in the southern and northern forest regions.Overall,the areas with decreased carbon storage were significantly larger than those with increased carbon storage.The findings provide a scientific basis for carbon cycle research,carbon management policy formulation,and ecological protection in the Ili region.关键词
