The database is derived from the UAV image data obtained from the field survey conducted by the Qinghai Tibet Plateau farmland ecosystem research team in 2020. The survey area involves the farmland ecosystem concentration areas and counties along Sichuan and Tibet 318, including Litang and Batang in Sichuan, and the areas such as Basu, Linzhi, Gyangze and Bailang in Xigaze in Tibet. The recorded objects include highland barley Traditional crops such as wheat, as well as open field vegetables and greenhouse facilities in some areas; The flight altitude is generally 50-300m, with high resolution. The photographing equipment is Dajiang yu2pro. The picture comes with GIS longitude, latitude, altitude and other information, which can be used for ground reference or correction data of satellite remote sensing.

This dataset is about the historical yield data (yield per unit area and sown area) of the main crops (hull-less barley and wheat) on Tibetan Plateau between years 1988-2018, covering some prefectures and cities located in Tibetan Plateau. The data are obtained from Tibet Statistical Yearbook, Qinghai Statistical Yearbook, Sichuan Statistical Yearbook, Gansu Statistical Yearbook, Yunnan Statistical Yearbook and the aba Tibetan and Qiang Autonomous Prefecture and Ganzi Tibetan Autonomous Prefecture Agriculture and Animal Husbandry Bureau with the same accuracy. Hull-less barley and wheat are the main crops on the Tibetan Plateau. This data set is of great value for the study of food security and agricultural production on Tibetan Plateau.

This data set is based on the field survey data on farmland production, operation and management in Tibet's one river and two rivers region, Southeast Tibet, Sichuan Tibet East Hengduan Mountain Area in 2020. Sample selection: for the areas of one river and two rivers in Tibet, Southeast Tibet, and Hengduan Mountain Area in East Sichuan and Tibet, first, the typical sampling method is used to determine the sample counties, sample towns, and sample villages; Then, according to the basic situation of farmers, one sample Township and one sample village are selected from each county. Finally, one farmer is randomly selected from each sample village by using the random sampling method. The data set records the basic information of the investigated land, the basic information of the interviewed farmers, including education level, consumption level and other information, agricultural planting area, etc. The data set is the data obtained through field investigation and interview, which can be used to analyze the basic situation of agricultural planting on the Qinghai Tibet Plateau, and provide a theoretical basis for further improving the countermeasures and suggestions of government support policies.

The dataset of Maize yield in Zhangye Basin in the Northern foot of Qilian Mountains (2001-2015) is obtained by downscaling the actual maize yield data based on the simulation results of Hydrological-Ecological Integrated watershed Flow Model (HEIFLOW). HEIFLOW is a three-dimensional distributed eco-hydrological coupling model, integrating the Precipitation-Runoff Modeling System (PRMS) with the Modular Groundwater Flow Model (MODFLOW) and several ecological modules, which can completely describe the hydrological cycle and vegetation ecological process of the basin. For the modeling details of generating this data, please refer to Han et al. (2021), and for the technical details of HEIFLOW model, please refer to Han et al. (2021), Tian et al. (2018), and sun et al. (2018)
