贡嘎山东坡土壤颗粒组成数据（2019年）

本数据为贡嘎山东坡针叶林、阔叶林和混交林土壤颗粒组成数据，包括如下指标：粘粒含量、粉粒含量和砂粒含量。将风干后的散土样过2 mm筛分离出石砾（>2mm），利用排水法测定石砾体积并烘干后称重，过筛后的土样采用激光粒度仪测定其颗粒组成（Mastersizer 3000， Malvern Instruments Ltd， 英国），获得土壤石砾含量、砂粒含量、粉粒含量和粘粒含量。This dataset provides soil particle composition data from coniferous, broad-leaved, and mixed forests on the eastern slope of Gongga Mountain, with core measured indicators including clay content, silt content, and sand content. The experimental procedures are as follows: Air-dried bulk soil samples were sieved through a 2 mm mesh to isolate gravel particles (>2 mm). The volume of the isolated gravel was measured using the drainage method, and the gravel was weighed after oven drying. The sieved soil samples were then subjected to particle composition analysis with a laser particle size analyzer (Mastersizer 3000, Malvern Instruments Ltd., UK), allowing the acquisition of soil gravel content, sand content, silt content, and clay content.
