A dataset of sulfur content and density of vegetation on the Tibetan Plateau

Field sampling was conducted during July to August in 2019–2020. The Tibetan Plateau (TP) was sampled on a grid basis (0.5° × 0.5° geographic grids), with three randomly set sample squares in each grid. We collected plant samples of different organs (leaves, branches, stems and roots) covering a total of 680 sites of forest (20 m × 20 m), shruband (20 m × 20 m), grassland (1 m × 1 m) and desert (1 m × 1 m)quadrats, and recorded the basic information (longitude, latitude, altitude, etc.) of the sites. These plant samples are classified, cleaned, dried, weighed and ground. An inductively coupled plasma emission spectrometer (ICP-OES) was used to measure the sulfur content in plant samples. Finally, we calculated the sulfur density and storage of different vegetation types.
