中国西北典型干旱区盐渍化土壤含盐量与地表高光谱观测数据集

本数据集围绕中国西北典型干旱区土壤盐渍化问题，基于野外实地采样与实验室分析，系统整理了盐渍化土壤含盐量与地表高光谱观测数据。研究区域包括甘肃省高台县、甘肃省景泰县和青海省格尔木市，分别代表河西走廊、黄河灌溉区和柴达木盆地等不同自然地理与盐渍化成因背景。数据集包含地表 0–10 cm ...This dataset focuses on soil salinization in typical arid regions of Northwest China, systematically collating salinity data of salinized soils and surface hyperspectral observation data based on field sampling and laboratory analysis. The study areas include Gaotai County and Jingtai County in Gansu Province, and Golmud City in Qinghai Province, which respectively represent different physical geography backgrounds and salinization genesis contexts such as the Hexi Corridor, Yellow River Irrigation Area, and Qaidam Basin. The dataset contains surface 0–10 cm ...
