In the context of rapid urban development, the development of construction land has become the main form of urban land use. While urban space is being developed, the unreasonable use of construction land has generated a large amount of inefficient land, which poses obstacles to the future development of the city. The relevant staff should construct a locally adapted urban inefficient land identification and evaluation index system, and use multisource data to conduct spatial overlay analysis on construction land. The results show that the city where the research area is located is in the late stage of urbanization, with an urbanization level above 70% and a relatively slow urbanization speed. However, the economic development level is on the rise, and inefficient land is mainly distributed in the central, western, and northern regions of the research area.
