Taking the central district of Yiyang City as an example,the evaluation index systems of urban development potential and geological environment suitability are constructed,and the comprehensive evaluation of urban development potential and geological environment suitability is carried out,and the coupling coordination relationship between them is analyzed by using the coupling coordination degree model.The results show that the coupling coordination degree of urban development potential and geological environment suitability in the central urban area of Yiyang is in high level,among which the basic coordination and severe discoordination areas are less than 2％of the study area.There are four subtypes that the urban development potential lags behind named Class Ⅻ and Class Ⅸ and the geological environmental suitability lags behind named Class Ⅺ and Class Ⅷ in senior coordination and basic areas.Among these,the areas in the former two subtypes need enhance urban development potential through the construction of infrastructure and public service facilities,while the areas in the latter two subtypes should appropriately raise the standards for geological safety risk prevention based on the implementation of national and local policies.
