1) Data Content: CT scanning dataset of three-dimensional spatial structure of vegetation-soil-rock in typical small watersheds of the Qilian Mountains. The dataset includes volume density data of moss layers at different depths, soil macroporosity and volume density of soil gravels in typical small watersheds of the Qilian Mountains.
2) Data Source and Processing Method: Intact soil columns with a depth of 30 cm under moss cover and the corresponding moss layers were collected from the typical small watersheds of the Qilian Mountains. Industrial X-ray three-dimensional microscopy was used to scan the moss layers and intact soil columns.
3) Data Quality Description: The scanning resolution of the moss layers is 40 μm, while the scanning resolution of the intact soil columns is 68 μm.
4) Data Application Achievements and Prospects: This CT scanning dataset of three-dimensional spatial structure of vegetation-soil-rock in typical small watersheds of the Qilian Mountains is of great significance for ecological restoration, water resource management and utilization in the Qilian Mountain region. It can provide basic data and theoretical support for elucidating the water conservation function and its underlying mechanism of the Qilian Mountains.
