Study on Novel Structures the Coordinated Development between Urbanization and Water Environment in Huzhou City, China

Taking Huzhou city as an example, the landscape spatial pattern and water quality were selected respectively as the space urbanization module and water environment level module, to construct the coupling coordination degree assessment index system. Entropy method was used to calculate the index weight and the comprehensive evaluation value of urbanization and water environment, and coupling coordination degree model to analyze the coordination degree between them. The results indicate that the coupling coordination degree between urbanization and water environment in the study period presented a fluctuation trend of deteriorating fist and improving afterwards, overall in barely coordination state, and the coordination function was weak. The coupling coordination types show a volatility trend in the way of urbanization lag-water environment retarded-urbanization lag. Analysis of the coordination between urbanization and water environment could provide theoretical bases and policy implications for achieving both goals of the urbanization level progress and water environment protection.
