中文摘要	[目的]研究内蒙古阿拉善左旗腰坝绿洲土壤盐渍化特征及土壤盐分离子分布规律,为研究区农业生产发展及生态环境保护计策提出合理依据。[方法]通过在野外考察、GPS定点、样品采集和处理并借助Excel和SPSS软件,运用统计学方法研究了该区土壤盐离子含量、总碱度与土壤离子含量之间的关系、土壤含盐量以及盐离子间的相关性。[结果]灌区土壤pH值平均值为8.13,为碱性土,土壤盐分含量较高,其中010cm土壤盐离子含量最高,平均值达到4.49%。阳离子主要是Ca~(2+)和K~++Na~+,阴离子主要是SO_4~(2-) >Cl~->HCO_3~-,CO_2- 3含量微小。010cm土层和1060cm土层中SO_4~(2-)与Ca~(2+)均有极显著正相关,相关性均大于0.95,因子分析中SO_4~(2-)与Ca~(2+),Cl~-和K~++Na~+发生聚类现象。[结论]灌区盐渍化土主要为硫酸盐渍土,其次为氯化盐渍土,该盐渍土危害植被生长。
英文摘要	[Objective]To study the characteristics of soil salinization and the distribution of soil salt ions in Yaoba Oasis of Alax Left Banner in Inner Mongolia Autonomous Region,and to provide a certain basis for the development of agricultural production and ecological environment protection.[Methods]We studied the distribution of soil salinization,the relationship between ion content and values of total alkalinity,salt ion content,as well as the relationship between salt amount and ion content by the means of sampling,GPS positioning and statistical methods.The testing results were analyzed with Excel software and SPSS software. [Results]The average pH value of the irrigation area soil is 8.13,it is alkaline soil.Land of Yaoba Oasis is high in salt content.The salt content of soil is mostly concentrate in 010cm depth,which can reach 4.49% .Cations are mainly Ca~(2+)and K~++Na~+,whereas anions are mainly SO_4~(2-),Cl~-,HCO_3~-in the study area,having a rank as:SO_4~(2-) >Cl~->HCO_3~- .Content of CO_2- 3 accounts for few proportion.There are significant positive correlations between SO_4~(2-) and Ca~(2+)both in 010cm soil layer and 1060cm soil layer,and their correlation coefficients are more than 0.95.Factor analysis showed that there are significant ties between SO_4~(2-) and Ca~(2+),and between anion Cl~-and cations of K~++Na~+.[Conclusion]The salinized soils in the irrigation area are mainly sulphate and chloride saline soils,which are harmful to the growth of vegetation.
