- Abstract
The scientific and reasonable delineation of an urban area serves as an important basis for making urban and rural statistics, formulating urban and rural policies, and implementing land space planning, At present, a unified concept system and unified delimitation methods of urban areas are yet to be established, which brings a lot of uncertainty to the formulation and implementation of land space planning, Therefore, aiming at the problems of the fuzzy concept, inconsistent demarcation methods, unclear spatial boundaries, this paper defined the spatial connotation of urban areas based on extensive research and proposed the spatial delimitation method of urban areas using surveying and mapping geographic information and the techniques such as remote sensing, Based on the data of the Third National Land Survey, this study determined the surface features incorporated into urban areas according to urban land use characteristics and spatial connection successively, in order to extract the spatial scopes of urban areas, Finally, taking Bazhong City as a case study, the rationality and feasibility of the process were verified, indicating that the method can be used in the extraction of the spatial scopes of urban areas and has the value of widespread applications.
