摘要: 本文根据盐渍土与自然条件的关系,分析它们在彩色红外航空象片上的解译标志,讨论了天然文岩渠流域土壤盐渍化地球化学分异的特点。分析表明:在彩红外航片上,盐渍土图斑的几何图形取决于盐渍土的分布环境,共色调与盐渍化程度密切相关,而盐渍化程度又随季节发生时间分异。

Abstract: This article analyses the interpretation signature of saliniration of soil on IR color photography on the basis of the relation between salinization and natural conditional discusses the fetures of geochemistry differentiation of salinization in Tianran Wenyan channel valley. According to the analysis, patterns of salinized soil on IR color photography depend on the distribution environments of salinized soil, and tones are crodely related with the degrees of salinization which appear time differentiation with seasons.
