Land use is considered the second largest source of carbon emissions， and the territorial space use regulation plays a crucial role in balancing the development of urban， agricultural， and ecological spaces， thereby significantly advancing the achievement of the ”dual carbon” goals. This article systematically analyzes the connotation， characteristics， internal mechanisms， and theoretical logic of territorial space use regulation under the green and low-carbon goals， and explores the pathways for transforming the territorial space use regulation that is compatible with the "dual carbon" goals. The results show that China is gradually building a comprehensive， full-chain， and systematic territorial space use regulation system， shifting from a "single-element" system that mainly focuses on agricultural and construction land to a "full-element" system including ecological space. To promote green and low-carbon transformation in this process， it is essential to integrate the concept of “ecological priority and green development” into development and construction，implementing specific measures such as "natural carbon sequestration in ecological spaces and technical emission reductions in urban and agricultural areas." And a full chain implementation path should be established， comprising “national spatial identification”， “precise zoning control”， “innovative control tools” and improved supporting systems”. The transformation of green and low-carbon space in the context of climate change implies balancing development and protection， integrating the “dual carbon” goals into spatial development， to jointly create high-quality and sustainable national space across the entire region.
