The delimitation of urban growth boundary has always been the focus and hotspot of urban expansion regulation research. In recent years, the application of Flus model provides new ideas and methods for the delimitation of urban growth boundary. However, the existing literature mostly focuses on the research area of city and county, and pays more attention to the specific delimitation of urban growth boundary, and less on the provincial level and the expansion effect after delimitation. In this regard, this paper takes Jiangsu Province as an example , selects three periods of land use data in 2010, 2015 and 2020 and factor data such as elevation, slope, population, GDP and traffic accessibility factors as the basic database, uses the Flus model to simulate the land use change in Jiangsu Province in 2030 and delimit the urban growth boundary, and calculates the carbon emission effect after delimiting the urban growth boundary based on the carbon emission coefficient of various land types. This study comprehensively considers the delimitation of urban growth boundary and its carbon emission effect at the provincial level, which is conducive to the regulation of urban expansion in Jiangsu Province and provides some reference for realizing the goal of carbon peak and carbon neutralization.
