The entropy method and coupling coordination degree model were integrated to evaluate the coupling coordination degree between urbanization and the eco-environment in Mongolia during 2000-2016. The results showed that the coupling coordination degree between urbanization and the eco-environment in Mongolia was generally at the stage of seriously unbalanced development, and that the main contributor of the urbanization and the eco-environment subsystem were demographic urbanization and eco-environment endowment, respectively. The southern part of Mongolia central zone should be paid more attention due to the lower degree of coupling coordination between urbanization and the eco-environment. To promote the healthy urbanization development in Mongolia, six-layer eco-city establishing green development pattern is proposed to provide scientific support for Mongolia.展开更多

An evaluation index system was constructed,and index weights were obtained using the variation coefficient method. The traffic volume was found to be the main factor contributing to transport superiority degree, and space urbanization was the primary factor influencing comprehensive urbanization. The coupling degree between transport superiority degree and urbanization( CU) was generally higher than the coupling coordination degree( DU) in 2000-2011. DUvaried more significantly than CU. In 2011, Sichuan was divided into five regional types. Based on the above observations, targeted recommendations were developed.展开更多
