中国未来逐年城市扩展过程和城市空间增长边界数据集（2021-2100）V1.0

本数据集来源于论文：Huang, M., Wang, Z.C., Pan, X.H., Gong, B.H., Tu, M.Z., & Liu, Z.F. (2022). Delimiting China's urban growth boundaries under localized shared socioeconomic pathways and various urban expansion modes. Earth's Future, 10, e2021EF002572。本套数据集展示了不同社会经济情景和不同扩展模式下中国2021-2100年城市建成区的扩展过程和城市空间增长边界（也可称为城市扩展边界）。本数据集的制作流程主要包括：（1）基于本地化后的共享社会经济路径，利用基于斑块的LUSD-urban模型，模拟了11种扩展模式下的城市扩展过程；（2）基于最大扩展范围，利用空间形态学方法对城市扩展动态信息进行处理，划定了中国各省级行政区的城市空间增长边界。作者利用该套数据分析了不同情景和不同扩展模式下城市扩展过程对生态系统服务的影响以及城市收缩压力，可为合理划定城镇开发边界提供参考。

This dataset is sourced from the paper: Huang, M., Wang, Z.C., Pan, X.H., Gong, B.H., Tu, M.Z., & Liu, Z.F. (2022). Delimiting China's urban growth boundaries under localized shared socioeconomic pathways and various urban expansion modes. Earth's Future, 10, e2021EF002572. This dataset illustrates the urban built-up area expansion process and urban spatial growth boundaries (also referred to as urban expansion boundaries) of China from 2021 to 2100 under different socioeconomic scenarios and various urban expansion modes. The production workflow of this dataset mainly includes two parts: (1) Based on the localized shared socioeconomic pathways, the patch-based LUSD-urban model was used to simulate the urban expansion processes under 11 expansion modes; (2) Based on the maximum expansion extent, the dynamic urban expansion information was processed using spatial morphological methods, and the urban spatial growth boundaries for each provincial-level administrative region of China were delineated. The authors utilized this dataset to analyze the impacts of urban expansion processes on ecosystem services and urban shrinkage pressure under different scenarios and expansion modes, which can provide references for the rational delimitation of urban development boundaries.
