河湟谷地耕地空间分布格局数据集（1726）

河湟谷地是青藏高原最主要的农业发展区之一，尤其到了清朝，该区土地覆被发生了重大变化，通过整理、校正该区历史文献中记载的1726年田亩数据，以期为揭示青藏高原典型河谷农业区耕地变化和人类活动的基本状况提供理论依据。本数据包含河湟谷地1726年耕地空间分布格局栅格数据，空间分辨率为1km×1km。1726年河湟谷地耕地数据主要来自于成书于乾隆二十年的《西宁府新志》、《循化厅志》《甘肃新通志》。县域行政界线的确定参考谭其骧主编的《中国历史地图集》及牛汉平主编的《清代政区沿革综表》。搜集耕地数据后将原始田亩数据进行校正，将历史耕地数据转换为统一的现代单位（km2），后采用网格化模型将耕地数据进行空间化。

The Hehuang Valley is one of the primary agricultural development zones on the Qinghai-Tibet Plateau. Significant changes in land cover occurred in this region, particularly during the Qing Dynasty. By collating and correcting the mu-based farmland data recorded in local historical documents in 1726, this dataset aims to provide a theoretical basis for revealing the changes in cultivated land and the basic status of human activities in typical valley agricultural areas of the Qinghai-Tibet Plateau. This dataset contains raster data depicting the spatial distribution pattern of cultivated land in the Hehuang Valley in 1726, with a spatial resolution of 1 km × 1 km. The 1726 cultivated land data of the Hehuang Valley are primarily sourced from 'New Gazetteer of Xining Prefecture', 'Xunhua Ting Gazetteer' and 'New General Gazetteer of Gansu', which were compiled in the 20th year of the Qianlong Reign. The county-level administrative boundaries were determined with reference to 'Collected Historical Atlas of China' edited by Tan Qixiang and 'Comprehensive Table of Administrative Changes in the Qing Dynasty' edited by Niu Hanping. After collecting the original farmland data, the raw mu-measured figures were corrected, the historical cultivated land data were converted to the modern unit (km²), and spatialization of the cultivated land data was then conducted using a grid-based model.
