| 1. | The interspecific association and correlation of 36 dominant species of the wetland vegetation were analyzed by using x2 - test , pearson ' s coefficient and spearman ' s coefficient . the results shown that those dominant populations composed 630 species - pairs ; among the 36 species were herbs , and the higher significant association ' s or correlation of species - pairs were 49 , 88 , 71 , respectively , moreover , the significant association ' s or correlation of species - pairs were 31 , 9 , 7 , respectively 采用x ~ 2检验、 pearson积矩相关系数和spearman秩相关系数等方法对湿地植物群落的种间关系研究,结果表明: 36个建群种群和优势种群构成的630个种对(其中主要是草本植物) ,其中极显著关联的种对数分别为49 、 88 、 71 ,显著关联的种对数分别是31 、 9 、 7 。 |
