青藏高原多年冻土区土壤水分与容重数据集（2022）

本数据集由科考队员于2022年野外土壤探坑调查完成，共20个土壤探坑，空间范围33.21°N-35.90°N；78.87°E-85.63°E。数据集以高寒荒漠和高寒草原生态系统为主，海拔范围在4530-5198m之间，土层深度在0-400cm之间。调查数据包括地点，经纬度，海拔，地表植被类型，主要土层深度，容重、含水率。该观测数据为编制青藏高原多年冻土分布、厚度、地下冰和活动层厚度数据产品奠定了数据基础。This dataset was generated from field soil pit surveys conducted by scientific expedition members in 2022, involving a total of 20 soil pits. The spatial scope of the survey area ranges from 33.21°N to 35.90°N and 78.87°E to 85.63°E. The study areas are dominated by alpine desert and alpine steppe ecosystems, with elevations ranging from 4530 m to 5198 m and soil layer depths ranging from 0 to 400 cm. The survey data includes location, longitude and latitude, elevation, surface vegetation type, main soil layer depth, bulk density and soil moisture content. This observational dataset lays a solid data foundation for the development of data products related to permafrost distribution, thickness, subsurface ice and active layer thickness on the Qinghai-Tibet Plateau.
