The dataset is the soil fertility data of Muli coal mine area on the Qinghai Tibet Plateau from 2000 to 2020. It is issued every five years, including five periods in 2000, 2005, 2010, 2015 and 2020; A total of 15 image data. The dataset covers a rectangular area (98.82 ° E-100.84 ° E, 37.5 ° N-38.25 ° N), defined by four vertexs of the southeast and northwest of Muli coal mine. The dataset is in grid format, with a spatial resolution of 30m, and the dataset format is GeoTIFF. The dataset takes the 30m surface albedo obtained by spatiotemporal fusion of GLDAS-2.1 albedo products and Landsat 5/8 albedo products, and the 30m surface temperature obtained by spatiotemporal fusion of GLDAS-2.1 surface temperature products and Landsat 5/8 surface temperature products as independent variables. Combined with the multiple regression model, the five-year dataset of total nitrogen（Unit: g / kg）, total phosphorus （Unit: g / kg）and total potassium （Unit: g / kg）in Muli coal mine area from 2000 to 2020 is regressed. The multiple regression model adopts the measured data of Huangshui River Basin stations in May 2018. On the premise that the independent variables are the albedo and surface temperature of Landsat 5/8, and the dependent variables are the total phosphorus, total nitrogen and total potassium observed in the field, the multiple regression model is established. These datasets fill the gap of high spatial resolution soil fertility dataset in Muli coal mine, and provide support for the study of temporal and spatial changes of soil fertility in Muli mining area.

File naming and required software

File name: the soil fertility data of Muli coal mine is stored in GeoTIFF format. The name of the file is "Muli_##_yyyy.TIF", where Muli represents Muli coal mine, ## represents soil fertility index, and yyyy represents year, such as Muli_TP_2010.TIF represents this GeoTIFF document to describe the total phosphorus status of Muli coal mine in 2010.
Data reading method: all GeoTIFF files in the dataset can be opened with ArcGIS or envi. The main content numerically characterizes the status of total phosphorus, total nitrogen and total potassium in Muli coal mine.
