A Change Analysis of Land Use and Carbon Storage in Maoming Based on the InVEST Model and GIS

DOI: 10.22161/ijeab.84.10

Abstract:
With the increasing attention paid to ecological and environmental issues, the monitoring and exploration of carbon storage have become increasingly important in ecosystems, attracting numerous attentions from academia and industry. Based on the era background of "double carbon", this study first discussed and sorted out the relevant theories, analyzed the changes and characteristics of various categories in the study area based on land use data, and analyzed the spatial-temporal changes of carbon storages in Maoming City from 1980 to 2020 through transfer matrix and dynamic degree analysis and the InVEST model to explore the impact of land use change on carbon storages. The analysis results show that there is a positive correlation between carbon storage and vegetation coverage, and the transfer of arable land and forest land is the main reason for the decrease in carbon storage. Therefore, it is recommended to pay attention to optimizing land use structures and controlling the expansion of construction land caused by urbanization in order to achieve the goal of protecting the ecological environment.
