Urbanization and ecological civilization construction are closely related, promote each other and restrict each other. By analyzing the coupling mechanism of the urbanization in metropolitan circle area and its ecological civilization construction, this paper constructs comprehensive evaluation index system for the urbanization and the ecological civilization construction, takes 9 cities of Wuhan Metropolitan Circle as research object, and uses comprehensive evaluation model, coupling coordination degree model and relative development model to analyze the interactive relationship between the urbanization of Wuhan Metropolitan Circle and its ecological civilization construction during 2007-2017 and to study its influencing dynamic factors. Research results show that the level of both the urbanization and the ecological civilization construction demonstrates the increasing trend annually but the ecological civilization construction lags behind the urbanization development, that regional difference degree gradually weakens, that spatial development pattern becomes “high in the east but low in the west” from “high in the west but low in the east”, therefore, the unbalance and insufficient problems are still prominent. The total coupling coordination level of Wuhan Metropolitan Circle stays at initial coordination period and is initial synchronization development type but the difference of the coupling coordination development stage between each city is obvious, and economic growth rate is higher than the growth rate of the coupling coordination degree. Endogenous power is not sufficient to develop the coupling coordination degree, outward power has positive impact on the coupling coordination degree but the negative effect of governmental power on the coupling coordination degree is not significant.
