This dataset subsumes sustainable livestock carrying capacity in 2000, 2010, and 2018 and overgrazing rate in 1980, 1990, 2000, 2010, and 2017 at county level over Qinghai Tibet Plateau. Based on the NPP data simulated by VIP (vehicle interface process), an eco hydrological model with independent intellectual property of the institute of geographic sciences and nature resources research(IGSNRR), Chinese academy of Sciences(CAS), the grass yield data (1km resolution) is obtained. Grass yield is then calculated at county level, and corresponding sustainable livestock carring capacity is calculated according to the sustainable livestock capacity calculation standard of China(NY / T 635-2015). Overgrazing rate is calculated based on actual livestock carring capacity at county level.The dataset will provide reference for grassland restoration, management and utilization strategies.
The data set records the urbanization rate data of each state of kazakhstan from 2000 to 2018.The data is from kazakhstan's national statistics bureau. Urbanization is a concept with broad implications.In a narrow sense, it generally refers to the urbanization of population, which refers to the increase of the number of cities and the expansion of the urban scale, and the process of population aggregation to cities in a certain period.Urbanization rate refers to the proportion of permanent urban residents in a region in the total permanent resident population.The name of the original index is Russian, which has been translated and edited.The accuracy of the official data can provide basic data basis for the study of the socio-economic development of central Asian countries.

To better protect these precious natural heritages, rationally develop and utilize natural resources and carry out scientific research, since 1975, 11 natural reserves have been established in Qinghai province, which cover an area of 21,805,400 hectares. They account for 30.2% of the land area of Qinghai province. Six of these natural reserves are national reserves that cover an area of 20,625,900 hectares, and five are provincial reserves that cover an area of 1,179,550 hectares. Among the provincial natural reserves, the Geermu Populus Euphratica Forest and the Beichuan River Reserve in Datong County of Qinghai have already applied to be national natural reserves. Until the end of 2012, eleven natural reserves—5 national and 6 provincial—have been established. Data were extracted from the Chinese Nature Reserve Specimen Information Sharing Infrastructure.
