祁连山北坡-河西走廊干旱荒漠区土壤剖面照片集（2019-2020）

土壤剖面指从地面垂直向下的土壤纵剖面，也就是完整的垂直土层序列，是土壤成土过程中物质发生淋溶、淀积、迁移和转化形成的。不同类型的土壤，具有不同形态的土壤剖面，土壤剖面可以表示土壤的外部特征，也能反映土壤的形成过程及土壤性质。祁连山北坡-河西走廊干旱荒漠区土壤剖面照片集（2019-2020）反映了该区域不同取样点的土壤剖面特征。本数据集土壤剖面照片均来源于2019年祁连山北坡-河西走廊干旱荒漠区综合土壤调查。该数据集对于解析土壤剖面地球化学组成特征、土壤形成的地址背景以及成壤作用具有重要的指示意义。

Soil profile refers to the vertical soil section extending downward from the ground surface, i.e., a complete sequence of vertical soil layers, which is formed through the eluviation, illuviation, migration and transformation of substances during soil formation processes. Soils of different types exhibit distinct soil profile morphologies. A soil profile can not only demonstrate the external characteristics of soil, but also reflect its formation process and soil properties. The Soil Profile Photo Collection of the Arid Desert Area on the Northern Slope of the Qilian Mountains - Hexi Corridor (2019-2020) records the soil profile features of various sampling sites in this region. All soil profile photos in this dataset are derived from the comprehensive soil survey carried out in the arid desert area on the northern slope of the Qilian Mountains - Hexi Corridor in 2019. This dataset holds important indicative value for analyzing the geochemical composition characteristics of soil profiles, the geological background of soil formation, and soil genesis.
