%X This dataset provides information on the content of organic carbon, inorganic carbon, total carbon, particulate organic carbon, and mineral bound organic carbon in grassland soils in the arid regions of northern China. It also includes the climate, vegetation, and soil properties of corresponding sampling points. The data covers the peak season of vegetation growth from May to August 2020. A total of 30 independent sampling points were set up along a 4000 kilometer drought gradient, with a longitude of 92.48 ° -123.45 ° E and an altitude of 134-2894m. Three 0.5m × 0.5m replicate plots were set up in each sampling point's 50m × 50m plot, and three 0-15cm surface soil cores were collected using a 5cm diameter soil drill in each plot. Finally, a total of 180 soil samples were collected. The carbon components were separated using a wet sieve method and their content was determined using an elemental analyzer; The auxiliary variables (climate, plant biomass, soil properties) are all derived from publicly available datasets or papers. The data can provide basic support for the study of carbon cycling, carbon pool stability, and climate sensitivity in arid grassland.
