The application and future direction of "urban built-up area" under the background of territorial and spatial planning
The"multi-plan integration"necessitates a refined level of detail in territorial and spatial planning,which requires the support of fine"urban built-up areas"spatial data.Howev-er,previous efforts in urban-rural identification have lacked a unified conceptual definition and standardization for"urban built-up area",thus impacting the accuracy,reliability,and compara-bility of statistical data and posing obstacles to informed decision-making.To address this is-sue,the"Code of Practice for Standard Urban Built-up Area Delineation",released in June 2021,introduced a systematic framework for defining and delineating urban built-up areas.This framework relies on two core principles:high-precision surveying and assessments of the living environment,establishing"urban built-up area"focused on the residential environment and"physical urban built-up area"centered on actual built-up areas.This achievement has been applied in land use monitoring and other domains.However,the existing delineating method of urban built-up areas is still in the preliminary construction stage.It needs to be perfected through practice in the future.
