Dataset

Land use data: In 2010 and 2020, collected from second and third national land resource surveys as well as land use change surveys conducted by the State Council. The prefecture-level farmland area data was obtained by the China Land Survey Results Sharing Application Service Platform (https://gtdc.mnr.gov.cn/Share#/), while prefectures that underwent major adjustments of administrative divisions between 2010 and 2020 or lacked planning data were excluded. Additionally, we calculated farmland area using the China Land Use/cover Dataset with 30m spatial resolution from the Resource and Environment Science and Data Center (RESDC) of the Chinese Academy of Sciences.Planning quotas: The prefecture-level farmland protection quotas and the reported farmland area at base period were collected from provincial land use master plans for 2006-2020. Socio-economic factors: All data were collected from the China Statistical Yearbook, the China Land and Resources Statistical Yearbook or provincial statistical yearbooks, with missing data obtained from the population census yearbooks or prefectural statistical bulletins.

土地利用数据：数据采集年份为2010年与2020年，来源包括第二次、第三次全国土地资源调查及国务院组织开展的土地利用变更调查。地级行政单元的耕地面积数据取自全国土地调查成果共享应用服务平台（https://gtdc.mnr.gov.cn/Share#/），同时剔除了2010-2020年间行政区划发生重大调整或缺失规划数据的地级行政单元。此外，本研究还借助中国科学院资源环境科学与数据中心（Resource and Environment Science and Data Center, RESDC）发布的空间分辨率为30米的中国土地利用/覆被数据集，计算得到耕地面积。
规划指标：地级行政区耕地保护目标及基期上报耕地面积数据取自《2006-2020年省级土地利用总体规划》。
社会经济因子：所有社会经济数据均取自《中国统计年鉴》《中国国土资源统计年鉴》或省级统计年鉴，缺失数据通过人口普查年鉴或地级行政区统计公报补充获取。
