Study on Carbon Emission Impacts and Carbon Emission Reduction of Land Use Changes in the Yangtze River Delta Region from 2005-2020

Abstract

The article investigated the characteristics of land use and land cover and their effects on carbon emissions in the Yangtze River Delta region from 2005 to 2020 and predicted carbon emissions in the next ten years. The results show that the land use in the region is spatially territorial and quantitatively stable, with the area of cultivated land and forest land decreasing, the area of construction land and unused land increasing, and the area of grassland, forest land, and water not changing much; the degree of land use in the region tends to increase, and the areas with high degree are the economically developed eastern urban agglomerations, while the low degree is the western mountainous areas; The spatial variability of regional carbon emission intensity is changing, with the total amount showing an upward trend, the distribution direction converging toward coastal areas, and the spatial development direction of “northwest-southeast” expanding more intensely than “northeast-southwest”; the model predicts that carbon emissions will still be on an upward trend in the next ten years. Based on this, measures such as optimizing the land use structure and comprehensive development of woodland-grassland agglomerations are necessary to achieve carbon reduction targets.
