STUDY ON COORDINATION DEVELOPMENT OF ECOLOGICAL-ENVIRONMENT AND ECONOMY BASED ON COUPLING MODEL: A CASE STUDY OF WUHAN CITY

The environmental issues that accompany rapid economic growth have attracted the attention of the government and the public. Multiple non-linear and complicated interactions exist between the economy and environment subsystem. Accordingly, understanding the operating mechanism of the economy environment system and evaluating its coordination level are of immense significance for sustainable urban development. This study uses system dynamics (SD) to build a dynamic model of the economy environment system. Furthermore, a coupling coordination degree model (CCDM) that focuses on the coordination of the economy environment system is established using data from 2000 to 2013 for Wuhan City, China. Coordination assessment results based on the CCDM show that the coordination of the economy scenario performs the worst, the environment scenario performs best in the short term.
