Modeling the dynamics of urban and ecological binary space for regional coordination: A case of Fuzhou coastal areas in Southeast China

The linkage of urban planning and the dynamics of regional ecosystem services value (ESV) allows sustainable aims more accessible, which is increasingly interested by researchers. This paper combines urban expansion and eco-compensation to construct the urban-ecological coordinated development model (UECDM) which aims to find a new urban expansion mode basing on the balance of regional ESV. UECDM is composed of three modules: prediction of urban expansion, eco-compensation and spatial simulation. With this model, the urban expansion and eco-compensation of Fuzhou areas was simulated. The result shows: urban land has expanded 12,805 ha, with a total ESV loss of 688 million yuan. In order to obtain the balance of regional ESV, 1,142 ha of cultivated land and 3,316 ha of other land should be converted into forestland; 2,588 ha of cultivated land into tidal flats; 2,027 ha of other land into water areas. This model could produce quantitative results for decision makers during the rapid urbanization for sustainable development.
