Hehuang Valley in 1800 and 1900 mainly come from New Records of Xining Mansion, Records of Xunhua Hall and New Records of Gansu, which were written in Qianlong for twenty years. The determination of county administrative boundaries refers to Atlas of Chinese History edited by Tan Qixiang and Comprehensive Table of Administrative Region Evolution in Qing Dynasty edited by Niu Hanping. After collecting cultivated land data, the original farmland data is corrected, the historical cultivated land data is converted into a unified modern unit (km²), and then the grid model is used to spatialize the two periods of cultivated land data. Hehuang Valley is one of the most important agricultural development areas in Qinghai-Tibet Plateau. Especially in Qing Dynasty, after a large number of immigrants settled land, the land cover in this area changed greatly. By sorting out and correcting the data of farmland in 1800 and 1900 recorded in the historical documents of this area, the spatial pattern of cultivated land in Hehuang Valley in 1800 and 1900 was restored, in order to reveal the changes of cultivated land in typical valley agricultural areas of Qinghai-Tibet Plateau.

File naming and required software

"Reclamation rate data are stored in grid form, and the file names are HHGD1800KZL and HHGD1900KZL. HHGD stands for Hehuang Valley, 1800/1900 stands for year, and KZL stands for reclamation rate.
Data reading method: ArcGIS can be used to open the view and analysis."
