基于地域综合体识别的县域国土空间区划方法研究OA

To address the challenges of element coordination,structural adaptation,and functional conflicts in the high-quality development of county-level territorial space,this study constructs a"resource-population-industry"regional complex theoretical model.Using methods such as weighted kernel density analysis,DBSCAN spatial clustering algorithm,and exploratory spatial data analysis,the study proposes a three-in-one county-level territorial space zoning methodology consisting of"multi-source data fusion,functional element analysis,and spatial clustering analysis."The methodology is empirically applied to Xifeng District,Qingyang City.The results indicate that:1)The proposed zoning method can identify cross-administrative boundary spatial clusters of elements,forming community units for the high-quality development of"resource-population-industry"elements,thus effectively exploring cross-regional"city-town-village"coordinated planning methods.2)Based on the identification of regional complexes,the territorial space of Xifeng District is zoned into urban-rural integration,town-village integration,and rural symbiosis units according to zoning principles,with differentiated development models proposed.The urban-rural integration type accounts for 13.32％,the town-village integration type for 34.29％,and the rural symbiosis type for 52.39％.3)The precise identification of regional complexes within the county effectively solves the problem of extensive zoning and spatial mismatch of elements in county-level territorial space planning.
