横断山高山峡谷区地表粉尘性质数据集

本数据为横断山高山峡谷区地表粉尘性质数据集，包含磁化率和地球化学元素数据。磁化率和地球化学元素分析在兰州大学西部环境教育部重点实验室完成。磁化率使用Bartington MS 2型磁化率仪测定。地球化学元素分析在兰州大学西部环境教育部重点实验室完成，采用荷兰飞利浦公司生产的PW2403型X荧光谱仪（XRF）测量。该数据提供了青藏高原东部地区表层土壤的磁化率特征和地球化学元素特征，对理解现代气候因子与高原东部表土磁化率之间的关系以及认识青藏高原粉尘源区来源以及粉尘输送和大气环流模式具有重要的作用。

This dataset records surface dust property data from the alpine gorge region of the Hengduan Mountains, including magnetic susceptibility and geochemical element data. Both magnetic susceptibility and geochemical element analyses were completed at the Key Laboratory of Western China's Environmental Systems (Ministry of Education), Lanzhou University. Magnetic susceptibility was measured using a Bartington MS2 magnetic susceptibility meter. Geochemical element analyses were also conducted at the same laboratory, using a PW2403 X-ray fluorescence spectrometer (XRF) manufactured by Philips of the Netherlands. This dataset provides magnetic susceptibility and geochemical element characteristics of surface soils in the eastern Qinghai-Tibet Plateau. It plays a vital role in understanding the relationship between modern climatic factors and the magnetic susceptibility of surface soils in this region, as well as identifying the dust source regions of the Qinghai-Tibet Plateau and revealing the patterns of dust transport and atmospheric circulation.
