%X This data is based on the data of 2207 meteorological observation stations in China from 1981 to 2010 provided by the National Climate Center. By calculating the ratio of annual average precipitation P to annual average potential evapotranspiration E0, the annual average dryness index AI data of each station is calculated. Using altitude, temperature, precipitation, vegetation and other data as auxiliary variables, the 1 km grid data is interpolated using Geo Weighted Regression (GWR) method, Finally, the vector boundary of the Qilian Mountains region was cropped to generate the average dryness index (AI) data for the years 1981 to 2010
