摘　　要：应用X2检验、Pearson相关分析和Spearman秩相关分析研究了艾比湖湿地主要植物种的种间关系。总体关联度显示植物种间独立性较强;在19个主要植物种之间,呈显著正相关植物种对数较少,共计15对,为总种对的8.77%;显著负相关植物种对极少,Spearman秩相关检验中为5对,占总对数的2.92%,X2检验中只有1对;研究结果清楚地反映了植物种间关系以及它们在资源利用和生态位上的差异。Interspecific relationship of plants in Ebinur lake wetland were studied by using X^2-test、Pearson＇s correlation coeficient and Spearman＇s rank correlation coefficient.The general correlation test showed that there are more stronger independence in plants.Among the 19 main plant species,the number of significant positive correlation in the whole plants species are less,they are 15 pairs,only of 8.77% of the total.The number of significant negative correlation in Spearman＇s rank correlation coefficient are 5 pairs,it is only 2.92% in the whole,and only 1 pair in X^2-test.The results clearly showed the plants＇ interspecific relationships and their diferences in resource utilization and niches.
