Research on Low Carbon Planning Method of Resource Based City Based on Coupling of City Region and Central City -- A Case Study of Xingtai City

Abstract

Resource-based cities generally have "high energy consumption, high carbon emissions, and high pollution". Exploring low-carbon planning of resource-based cities means great significance for promoting the low-carbon transformation and development of resource-based cities and achieving "carbon peak" and "carbon neutrality". Based on the two levels of city region and central city, the paper proposes a low-carbon planning method for resource-based cities from four aspects: industrial transformation, land use, road transportation and ecological environment. At the city region level, it is necessary to reasonably determine urban industrial structure and industrial development scale, and meanwhile, optimize the industrial layout by reasonably planning production, living and ecological space and formulating practical space control measures; coordinating the connection between external traffic and traffic system within the city; constructing a carbon sink network composed of green patches-ecological corridors-peripheral matrix. At the central city level, it is necessary to analyze gradient attributes of carbon emissions from different land types, rationally arrange various types of construction land; optimize the layout of urban residence and employment space; increase systematicness of road planning in central urban areas; give full play to the carbon sink role of ecological corridors. Finally, an empirical study is carried out with the case of Xingtai City. The research can provide theoretical basis and path reference for reducing carbon emissions of resource-based cities through spatial planning.
