摘要 土壤盐分及其光谱特征是土壤盐渍化高光谱遥感定量监测的基础研究内容。茶卡-共和盆地位于柴达木盆地东部边缘,是土壤盐渍化
比较典型的区域之一。在研究区盐渍土野外调查采样的基础上,依据土壤理化分析和实验室光谱测量数据,对土壤盐分及其光谱特征进行了
分析,总结了茶卡-共和盆地盐渍土光谱特征随土壤盐分含量的变化规律。研究表明: 该区域盐渍土为氯化物盐土,以NaCl和MgCl2为主,有
少量的硫酸盐; 不同含盐量的盐渍土具有明显的光谱特征差异。

Abstract :The salinity characteristics and spectral characteristics of salt-affected soil constitute the basic research
contents in hyperspectral remote sensing quantitative monitoring of saline soil. The Caka-Gonghe basin is situated in the
eastern margin of the Qaidam Basin, where the soil salinization is typical. Based on the physical and chemical analysis of
the soil and laboratory spectra of the samples, this paper discusses the salinity characteristics and spectral
characteristics of the samples and analyzes the regularity of the variation of the spectral characteristics with the
salinity characteristics. Studies have shown that chloride saline soil is dominant in the study area, and that the spectral
characteristics show marked differences due to the different salinities in the saline soil.
