Abstract:Under the background of the South-to-North Water Diversion Project，taking Nanyang City as the study area，the relationship between land use structure and industrial structure change was studied.Land use data and three industrial structure data in Nanyang from 2009 to 2016 were collected.Firstly，the current situation of land use change and industrial structure in Nanyang was studied.Then the relationship between them was analyzed by information entropy model，correlation analysis and multiple linear regression analysis.The results showed that：（1）The area of construction land has shown an upward trend and the area of agricultural land has shown a downward trend；（2）The industrial structure has gradually shown the characteristics of “two，three and one”；（3）The information entropy and equilibrium degree of land use structure has shown an upward trend，the complexity of land use structure became higher and the balance of land use structure gradually increased，the information entropy of industrial structure was decreasing，the industrial structure has been continuously optimized；（4）The change of land use structure has been most affected by the primary industry and the tertiary industry.It showed that the primary industrial structure and the tertiary industrial structure were the main driving factors affecting the information entropy of land use structure.
