Abstract:

The delimitation of urban growth boundaries is of great significance for ensuring the rational use of resources and promoting the orderly development of cities and towns. Most existing studies mainly focus on the technical exploration of planning practice, while ignoring the quantitative assessment of the ecological environment to some extent. In addition, few studies have been carried out at the metropolitan area scale. This study takes Wuhan Metropolitan Area as the study case, and proposes to combine multiple factors to build a "dual environment evaluation" system. The FLUS model is used for land growth simulation and delineation of urban growth boundaries. Furthermore, the results are analyzed using the landscape metrics. The results show that: (1) the FLUS simulated urban area expansion demonstrates an applicable accuracy. The simulation results reveal that the urban built-up areas keep expanding, so it is necessary to delimit the development boundary to restrict urban development; (2) The delineated urban growth boundaries can prevent from urban construction occupying areas with high ecological or agricultural value, and improve the urban spatial layout of the Wuhan Metropolitan Area based on the optimization of spatial forms with strong applicability; (3)The evaluation of urban expansion driving factors shows that compared to a single factor library, the "dual environment evaluation" factor library has a higher accuracy, can optimize the landscape pattern, promote the development of construction land, and fill the gaps in the built-up area better, which is corresponded with regional development requirements; and (4) The evaluation of expansion analysis shows that the results are consistent with the expected development pattern of Wuhan Metropolitan Area, and government departments might pay attention to the potential value of the expansion in the airport region, the Yangluo region, the Optics Valley-Future City region, and the Zhifang region. The above shows the effectiveness of the FLUS model in the Wuhan metropolitan area, which also provides great reference for planning management and construction land optimization.
