Abstract

The accurate monitoring of the dynamic relationship between land use and carbon
storage can provide a scientific basis for the government to formulate carbon
emission reduction policies and promote the green development of cities, achieving
a win–win situation for both ecology and the economy. As a national central city
in southwest China, Chengdu has experienced rapid land-use changes in the past
decade due to the implementation of development strategies such as urban-rural
integration and the construction of a “Park City.” To explore the spatial and temporal
