| 摘 要： | 目的]以玛纳斯河流域中下游三种典型地貌的盐渍土为研究对象,对该区盐渍土进行分类和空间变异性研究.方法]对采集不同区域土壤样品,进行基本理化性质的分析,并结合统计学软件分析.结果]不同地貌下的土壤盐分组成及含量呈明显差异,流域中游的冲积扇扇缘带盐渍土属氯化物-硫酸盐类型;中下游的冲积平原土壤属氯化物类型;位于下游干三角洲属硫酸盐-氯化物类型.三种地貌土壤pH值在碱性与强碱性之间,变异系数都低于10;;各种盐离子均为中等变异.结论]通过对土壤含水率、总盐及各盐离子含量相关性分析表明,含盐量与Na+含量显著相关,但其它组分间的相关性在不同地貌下表现不尽一致.

| Abstract: | 【Objective】Basic characteristics and regional distribution research in arid inland area are the foundation of saline soil and salinity research work.【Method】Manas River basin was the research subject of this article.We chose typical salt accumulation zone that saline soil distributed widely on three types of landscape in the middle and lower basin of Manas River.On the basis of analysis and measurement for soil samples of our study,to study the spatial variability and classification of saline soil this basin were studied.【Result】Our results showed that soil salinity composition and content of different landscape were very different.As saline soil in the alluvial fan margin of middle reaches of the watershed is a chloride-sulfate type,type of soil in the alluvial plain of middle and lower reaches are chlorides,and located in the lower delta is sulfate-chloride type.The pH values among three landscapes is characteried by strong alkaline and alkaline,the CV is less than 10%,and the CV of soil salinity is the secondary.【Conclusion】By the correlation analysis of soil moisture,total salt and the salt ions,the results showed that the correlation between salinity and Na+ is markedly correlated,but the correlations of other components in different landscapes were not consistent. |
