Characteristics and Influencing Factors of Soil Shear Strength in Gully Erosion at Different Developmental Segments of Subalpine Meadows

The data were obtained from field sampling conducted in July 2024 in the gully erosion area of the subalpine meadow on Gaoben Mountain, Kunming, Yunnan Province. Laboratory analyses were completed at the Water-Saving Irrigation Experiment Center of Yunnan Agricultural University in Kunming. The dataset includes soil shear strength, physicochemical properties, and mineral composition from different gully segments (gully head, gully middle, and gully outlet) and positions (gully edge, gully wall, and gully floor) within the subalpine meadow gully system.

本数据集的数据来源于2024年7月在云南省昆明市高本山亚高山草甸沟蚀区域开展的野外采样。所有实验室分析工作均于昆明市云南农业大学节水灌溉试验中心完成。本数据集涵盖亚高山草甸沟蚀系统内不同沟段（沟头、沟中段、沟口）及不同位置（沟缘、沟壁、沟底）的土壤抗剪强度、理化性质与矿物组成数据。
