Evaluating the multifunctionality of land use at the county level is conducive to promoting the formation of a new pattern of territorial spatial development and protection, as well as facilitating the rational allocation of land resources in the context of urbanization. This paper constructs an index system for evaluating land multifunctionality from the economic, social, and ecological functions of land resources. Using relevant data from 38 districts and counties in Chongqing Municipality from 2011 to 2020 as samples, the multifunctionality of land use in each district and county of Chongqing Municipality is evaluated, and its spatiotemporal evolution characteristics are explored. The study shows that: (1)The overall functional enhancement of land use in each district and county of Chongqing Municipality is accompanied by a gradual reduction in spatial differences. The overall sustainability has increased from medium-low in 2011 to medium-high in 2020, exhibiting a spatial pattern of decreasing gradient from the main urban area to the new urban development areas in the northeast and southeast of Chongqing. (2)The economic function of each district and county in Chongqing Municipality has rapidly improved, with the main urban area exhibiting the strongest function and other districts and counties showing weaker spatial differentiation. The social function has increased rapidly, with higher levels observed in the main urban area and new urban development areas, and lower levels in the northeast and southeast of Chongqing. The improvement of ecological function in Chongqing Municipality is relatively limited, except for a few districts and counties showing relatively high enhancement, the overall ecological function remains poor.
