西南山地三省一市（分省市）城乡边界数据集（2020年）

西南山地三省一市（分省市）城乡边界数据集，该数据能够细致的描述西南山地三省一市实际城乡边界划分。该数据是基于地理大数据（POI信息点）、土地覆被数据（建设用地），利用ArcGIS平台空间分析，模拟（核密度估计与Densi-Graph 阈值法）获得。将传统城乡，划分为4类城乡边界，包括城市核心、城乡结合部、场镇和乡村。相对基于行政区划的传统城乡两级划分，该城乡边界能够更为细致精细的描述省市内部县域实际城乡空间分布，为城乡可持续发展与城乡规划提供较为准确的空间支撑。

Urban-rural Boundary Dataset of Three Provinces and One Municipality in the Mountainous Southwest China (classified by province and municipality). This dataset can accurately depict the actual urban-rural boundary divisions of the target region. It is generated based on geographic big data (POI points) and land cover data (construction land), through spatial analysis on the ArcGIS platform via simulation using kernel density estimation and Densi-Graph threshold method. The dataset divides traditional urban-rural areas into four types of urban-rural boundaries: urban core, urban-rural fringe, market town, and rural area. Compared with the traditional two-level urban-rural division based on administrative divisions, this dataset can more precisely describe the actual urban-rural spatial distribution of counties within each province and municipality, providing reliable spatial support for urban-rural sustainable development and urban-rural planning.
