Abstract:

The delimitation of urban development boundaries plays an important role in optimizing the nation land space. “Double evaluation” is one of the important means to study and predict the scale of new construction land in the future and to determine the spatial distribution of urban construction land. This study combines the “double evaluation” with the FLUS (Future Land-Use Simulation) model to study the delimitation of the urban development boundary of Yichang. The results show that: ① the “double evaluation” method comprehensively considers the carrying capacity of the resource environmental bear and the suitability of urban development; ② the FLUS model can better couple the “double evaluation” method for Land Use/Land Cover (LULC) suitability evaluation, Land Use/land Cover Change (LUCC) simulation and urban development boundary delineation, and the overall accuracy of the simulation reaches 96%; ③ according to the requirements of relevant national policies, this study divides the urban development boundary of the study area into concentrated construction areas, elastic development areas and special purpose areas. This function-based division can meet the requirements of urban flexible development, ecological protection and urban safety. This research combines the FLUS model, which is widely used in the simulation of LUCC, with the double evaluation method used in China’s new round of land and space planning to obtain the result of the urban development boundary. This result is consistent with the existing plan of the study area.
