艾比湖流域风沙土盐分特征分析
Salinity analysis of sandy soil in Ebinur Lake basin
摘要
Abstract
Using the sandy soil from Ebinur Lake basin as study object ,the contents of soil total salt and soluble ions under different conditions of vegetation coverage were measured ,and the characteristics of soil salinity were evaluat-ed by the methods of correlation analysis and principal component analysis .The results showed that the total salt content of sandy soil was high and quite different among sampling areas ,so it showed an extremely strong spatial variability .The total salt content was positively correlated with the contents of Cl - ,K+ +Na+ and SO42- at extremely significant level , but it was less correlated with the content of HCO3 - .The main anions in sandy soil were Cl - and SO42- and the main cations were K+ +Na+ ,so they were judged to be the characteristic factors of salinization according to principal compo-nent analysis .The salinization types of sandy soil were mainly chloride-sulfate type and sulfate type .关键词
