Historical data set of agricultural production, operation and management in Qinghai Tibet Plateau - effective irrigation area of farmland in Tibet Autonomous Region (1995-2018)

The database contains the historical data of agricultural production, operation and management of the Qinghai Tibet Plateau, which is collected and sorted from the statistical yearbooks of cities and states in the Qinghai Tibet Plateau over the years, extracted and summarized after electronization; This data includes the data of farmland effective irrigation area in sub counties within the scope of Qinghai Tibet Plateau from 1995 to 2018. The effective irrigation area of farmland is an important indicator of production, operation and management. The Qinghai Tibet Plateau is dominated by typical dry farming. In most areas, agricultural irrigation is dominated by natural precipitation, and the area covered by artificial irrigation is less. This data is of great significance for analyzing the management of water resources utilization and water footprint of farmland ecosystem in the Qinghai Tibet Plateau.

UAV-derived raster data of the Tibetan Plateau (2021)

This dataset was captured during the field investigation of the Qinghai-Tibet Plateau in June 2021 using uav aerial photography. The data volume is 3.4 GB and includes more than 330 aerial photographs. The shooting locations mainly include roads, residential areas and their surrounding areas in Lhasa Nyingchi of Tibet, Dali and Nujiang of Yunnan province, Ganzi, Aba and Liangshan of Sichuan Province. These aerial photographs mainly reflect local land use/cover type, the distribution of facility agriculture land, vegetation coverage. Aerial photographs have spatial location information such as longitude, latitude and altitude, which can not only provide basic verification information for land use classification, but also provide reference for remote sensing image inversion of large-scale regional vegetation coverage by calculating vegetation coverage.
