Abstract：
In September 2018, the authors selected alpine meadows with enclosure years of 5, 13, 22, and 39 a (enclosure experimental sites) at the Haibei National Field Research Station of Meadow, Qinghai Province, as the study object, and seasonal grazing meadows about 50 m away from the station were used as the control. The dataset of root morphology (including root length, root surface area and root tip) of different diameter classes were obtained by means of root scanner and cluster analysis for different grazing enclosure durations (0, 5, 13, 22 and 39 a). The results showed that there were some differences in the response of root morphology of different soil layers at different diameter classes to grazing enclosure durations; the root length, root surface area, and root tips of each diameter class at 13 years grazing enclosure grasslands were higher than those of other durations and seasonal grazing grassland, which had higher root ecological benefits. The dataset includes: (1) geolocation of the sample sites; (2) root morphology of different diameter classes; (3) Soil physiological properties of different grazing enclosure durations; (4) photos of the samples. The dataset is archived in .xlsx, .shp, .jpg, and .docx data formats, and consists of 13 data files with data size of 20.1 MB (Compressed into one file with 19.9 MB). The analysis article based on the dataset has been published in Acta Ecologica Sinica , Vol. 43, No. 8, 2023.
