Abstract

With the acceleration of urbanization, regional ecological security issues have become increasingly prominent. There is a complex relationship between urbanization and urban ecological security. This paper uses the method of system analysis to qualitatively describe the coupling relationship between urbanization system and urban regional ecological security system, and quantitatively evaluate the coupling and coordination relationship between these two systems. The results show that the spatial urbanization subsystem is the most driven to the urbanization system, and the ecological security response system is an important factor to maintain and enhance the urban ecological security. Therefore, the spatial urbanization subsystem and the ecological security response subsystem have the greatest influence on the coupled system between urbanization and urban ecological security. Taking Shaanxi Province as an example, it is analyzed that the coordination degree between Shaanxi's urbanization system and regional ecological security system is increasing from 2005 to 2016, and has experienced four stages : uncoordinated recession, low coordination, moderate coordination and high coordination. The coordination degree between urbanization development and urban ecological security has been continuously improved, indicating that urbanization development has a positive role in promoting urban ecological security.
