中文摘要	以民勤绿洲广泛分布的盐生植物盐生草为研究对象,对其周围不同距离范围内土壤盐渍化类型及盐分离子的相关性进行研究。结果表明:在距盐生草水平方向0-60 cm范围内,从阴离子组成来看,040 cm 土层土壤盐渍化类型为氯化物-硫酸盐型,40-60 cm 土层土壤为硫酸盐一氯化物型;从阳离子组成来看,0-40 cm 土层土壤盐渍化类型为钙钠盐型,4060 cm 土层土壤为钠盐型。同时盐生草周围土壤(0 -60 cm)盐分离子之间的Pearson相关分析结果和偏相关分析结果存在明显差异,其中偏相关分析相对能够更准确地反映多元变量其中两个变量之间的相关性,建议在研究类似盐分离子之间的相关性时采用偏相关分析。试验区盐生草周围土壤盐分离子的偏相关分析表明:距盐生草20,40 cm处,与土壤全盐含量相关性最高的阴阳离子分别为SO_4~(2-),Na~+;距盐生草60 cm处,与土壤全盐含量相关性最高的阴阳离子分别为Cl~-,Na~+。可见,在盐生草周围土壤(0-60 cm)中,土壤盐分主要是氯化钠、氯化钙、硫酸钠和硫酸钙。
英文摘要	Correlation of salt ions and salinization types of soil around different distance ranges from Halogeton Glomeratus were studied by using Halogeton Glomeratus of halophyte widely distributing in Minqin Oasis as the research example. The results showed that 0-60 cm distance from the Halogeton glomeratus in the horizontal direction, anion component of 040 cm soil layer belonged to chloride-sulfate type and belonged to chloride-sulfate type in 4060 cm soil layer, cation component in 040 cm soil layer belonged to calcium-sodium type, and belonged to sodium type in 4060 cm soil layer. Pearson correlation analysis and partial correlation analysis had clear difference among salt ions of Halogeton Glomeratus surrounding 060 cm range soil. Partial correlation analysis could more exactly reflect the correlation between two variables in multivariate,therefore, it was suggested that partial correlation analysis should be used when studying a correlation between similar salt ions. The partial correlation analysis of salt ions in soil around Halogeton glomeratus showed that in the horizontal direction away from the Halogeton glomeratus 20 cm and 40 cm, SO_4~(2-) and Na~+ had the highest correlation with soil total salinity. In the horizontal direction away from the Halogeton glomeratus 60 cm, Cl~- and Na~~+ had the highest correlation with soil total salinity. Thus, in the horizontal direction away from the Halogeton glomeratus 060 cm range, soil salinity mainly resulted from sodium chloride ,calcium chloride, sodium sulfate and calcium sulfate.
