青藏高原318个网格状表土样品24个常见孢粉类型百分含量数据

全面认识青藏高原现代孢粉与植被、气候及人类土地用的关系，是定量重建过去植被、气候及人类扰动强度的基础。依托第二次青藏高原综合科学考察研究项目，项目组开展网格状的表层土壤样品采集和植被调查工作，共采集700余个表层土壤样品。该数据集是阶段性完成的318个样品的孢粉百分比数据，这些样点已经能够涵盖青藏高原中东部地区的大部分区域，也能够涵盖高原的常见植被类型。该数据集可以用于构建孢粉与植被及气候的转换函数。

A comprehensive understanding of the relationships between modern pollen and spores, vegetation, climate, and human land use on the Qinghai-Tibet Plateau is fundamental to quantitatively reconstructing past vegetation, climate, and the intensity of human disturbances. Supported by the Second Tibetan Plateau Scientific Expedition and Research (STEP) Program, the research team carried out grid-based surface soil sample collection and vegetation surveys, with a total of over 700 surface soil samples acquired. This dataset provides pollen and spore percentage data for 318 samples obtained during the phased fieldwork. These sampling sites cover most of the central and eastern Qinghai-Tibet Plateau and encompass the common vegetation types present on the plateau. This dataset can be utilized to develop transfer functions that correlate pollen and spore assemblages with vegetation and climate.
