| Abstract: | Objective] Evaluating regional land use efficiency and its coupling relationship from three aspects of society, economy, and ecological environment is beneficial for achieving rational allocation of land resources and optimizing land use structure. Method] In this paper, taking 21 cities and prefectures in Sichuan Province as the research objects, a comprehensive evaluation system for land use benefit in Sichuan Province from 2010 to 2020 was constructed using the entropy weight TOPSIS method and coupling coordination degree model. Based on GIS technology, the coupling coordination relationship and spatiotemporal evolution characteristics of the social, economic, and ecological environmental benefits of land use were analyzed. Result] (1) the overall comprehensive land use benefit of various cities and prefectures in Sichuan Province was on the rise, with a spatial pattern of "high in the northwest and low in the southeast". The overall economic benefits of land use and ecological environmental benefits were showing an upward trend, manifested as a spatial pattern of "high in the west and low in the east" and "high in the central and western regions and low in the west", respectively. The overall social benefits of land use were showing a downward trend, with a spatial pattern of "high in the middle and low in the two wings". The three major benefits all had significant clustering characteristics in space. (2) There were four levels of land use coupling coordination in various cities and prefectures in Sichuan Province, with an overall coordination level that was not high, mainly being barely coordinated, followed by a near imbalance, and the spatial pattern being "high in the middle and low on the two wings". Cities with the same coupling level had higher aggregation, and the land use benefit coupling coordination level needs further improvement in spatial distribution. (3) The factors that affect the size of land use benefit in Sichuan Province were in the order of social > economic > socio-economic > social ecology > ecological environment benefit system. The coupling and coordination relationship of land use benefits was mainly influenced by a single factor of social and economic benefits, followed by social and economic composite factors, and then social and ecological composite factors. Conclusion] The overall comprehensive benefits of land use in various cities and prefectures in Sichuan Province were on the rise, with significant regional differences. The overall level of coupling coordination was at a lower level, and cities with the same coupling level had a higher degree of agglomeration. In future development, it is necessary to regulate the disorderly expansion of urbanization, pay attention to the construction of urban basic public services and other facilities, and increase the investment in urban environmental construction, promote the coordinated development of land economic benefits, social benefits, and ecological environmental benefits in Sichuan Province. The research conclusion aims to provide a reference for improving the comprehensive benefits of land use in Sichuan Province. |
