Beginning in 2000, Lianyungang's urbanization entered a period of rapid growth, spatially as well as economically.
Rapid and intensive expansion of "construction land" imposed increasing pressures on regional environment. With the
support of remote sensing data and GIS tools, this paper reports a "present-capacity-potential" integrated suitability
analysis framework, in order to characterize and evaluate the suitability of urban expansion in Lianyungang. We found
that during the rapid coastal urbanization process from 2000 to 2008, the characteristics of physical expansion in the
study area were characterized by a combination of high-density expansion and sprawling development. The land use
conversion driven by urbanization and industrialization has not occurred only in city districts, but also the surrounding
areas that were spatially absorbed by urban growth, while closely associated and greatly influenced by the explosive
growth of industrial establishment. The over-consumption of land resources in the areas with low environmental carrying
capacity, particularly in the eastern coastal area, should be strictly controlled. Compared to conventional land suitability
analysis methods, the proposed integrated approach could better review the potential environmental impacts of urban
expansion and provide guidance for decision makers.
