Abstract:The land use structure is a specific performance of land uses on the national economic structure, the evaluation of land use structure can improve the efficiency and function of land use. In this paper, based on GIS software, 38 counties in Chongqing City were selected as the research objects, the regulation degree and efficiency of land use structure were evaluated by using the information entropy theory and the data envelopment analysis (DEA) method. The results showed that there were significant spatial differences in the regulation degrees of land use structures in different counties of Chongqing, and the regulation degree had a close relation to the regional land use. There were significant spatial differences in the efficiencies of land uses in different counties, the values of comprehensive technical efficiencies, pure technical efficiencies and scale efficiencies of 20 counties were 1 or close to 1, which indicated that the land use structure in each county of Chongqing City was reasonable, the land use efficiency was good and the land development and utilization was orderly.
