REMOTE SENSING ANALYSIS OF SALINIZATION GEOCHEMISTRY IN TIXNRAN WENYAN CHANNEL VALLEY IN THE NORTHERN PART OF HENAN PROVINCE
豫北天然文岩渠流域土壤盐渍化地球化学的遥感分析

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.
