Abstract:

It is of great practical significance to carry out the assessment of land use carbon budget in functional areas and construct a carbon offset zoning optimization framework to formulate low carbon strategies for each functional area, specify compensation flows, and promote coordinated regional development. When taking Wuhan Urban Agglomeration as the basic analysis unit, this paper analyzes the spatial differentiation characteristics of land use carbon budget under the MFOZ, and the classification and conducts optimization of carbon compensation types in Wuhan Urban Agglomeration with the help of some methods, such as the Normalized Revealed Comparative Advantage Index method, the SOM-K-means model, and the two-dimensional correlation matrix. The results show that there are significant regional differences in the total amount of carbon emissions in different counties of Wuhan Urban Agglomeration, and display the spatial distribution characteristics that the total amount of carbon emissions is lower in the west and higher in the east, and the highest in the center. The land use carbon emission and carbon absorption in the MFOZ have obvious spatial differentiation characteristics, which shows a certain degree of relative spatial distribution trend. Wuhan Urban Agglomeration has been divided into 16 carbon compensation payment areas, 11 carbon compensation obtaining areas and 12 carbon compensation balance areas. In combination with the strategic objectives of the MFOZ, 7 types of carbon offset space optimization areas are eventually formed, and corresponding low-carbon development directions and strategies are proposed for each type of area.

Key words: Major Function Oriented Zones (MFOZ), land use carbon budget, carbon compensation zoning, space optimization, Wuhan Urban Agglomeration
