本研究对艾比湖不同水盐环境荒漠植物的种间关联特征进行了分析，并比较了关联种对间植物叶片功能性状（叶片C、N、P和S含量）的差异。结果表明：高水盐（盐胁迫）和低水盐（干旱胁迫）环境下，艾比湖荒漠植物种间总体关联性均呈现不显著负关联，种间关系相对松散。从关联种对来看，2种不同水盐环境均以正关联种对居多，其中，低水盐环境下正关联种对数明显高于高水盐环境，种间互利关系更占优势；高水盐和低水盐环境下，盐节木〔Halocnemum strobilaceum (Pall.) Bieb.〕与其他物种间多表现为负相关，相关系数为-0.48~1.00;高水盐环境下，显著正相关种对多见于生物量较低的物种间。正关联种对的叶片C、N和S含量差值总体表现为高水盐环境高于低水盐环境，而负关联种对叶片N、P和S含量差值在低水盐环境下更高。高水盐环境下正关联种对的性状（叶片P含量除外）差值总体高于负关联种对，但在低水盐环境下则相反。综合研究表明：干旱胁迫下种间竞争往往使种间功能性状趋异，而互利作用则使种间功能性状趋同；盐胁迫下性状相似种对的竞争更加激烈，互利种对的功能性状差异明显。

 The interspecific association characteristics of desert plants in different water-salt environments of Ebinur Lake were analyzed in this study, and the differences in leaf functional traits (contents of C, N, P and S in leaf) of associated species pairs were compared. The results show that in high water-salt (salt stress) and low water-salt (drought stress) environments, the overall interspecific association of desert plants of Ebinur Lake shows a non-significant negative association, and the interspecific relationship is relatively loose. In terms of associated species pairs, positively associated species pairs are more in two different water-salt environments, in which, the number of positively associated species pairs in low water-salt environment is evidently higher than that in high water-salt environment, and its interspecific beneficial relationship is more advantaged; in high water-salt and low water-salt environments, Halocnemum strobilaceum (Pall.) Bieb. mostly shows negative correlations with the other species, and the   correlation coefficients are -0.48-1.00; significantly positively correlated species pairs in high water-salt environment are more commonly found among species with relative low biomass. The difference values of contents of C, N and S in leaves of positively associated species pairs in high water-salt environment are higher than those in low water-salt environment, while the difference values of contents of N, P and S in leaves of negatively associated species pairs are higher in low water-salt environment. The difference values of functional traits (except for leaf P content) of positively associated species pairs are higher than those of negatively associated species pairs in high water-salt environment, but it is the opposite in low water-salt environment. In conclusion, the interspecific competition under drought stress tends to make interspecific functional traits different, while the beneficial effect makes the interspecific functional traits similar; the competitions between species pairs with similar traits are more intense under salt stress, and the differences in functional traits of beneficial species pairs are evident.
