Interspecific relationships of maj or species in Ammoden-dron argenteum communities of Takeermohuer Desert
摘要
Abstract
Based on the data from the field,the interspecific relationships of the major species in Ammodendron argen-teum communities of Takeermohuer Desert were studied by Fisher’s exact test for 2×2 contingency table,Pearson’s correlation coefficient and Spearman’s rank correlation coefficient test,coupled with DCA ordinatio.The results indi-cated that positive association coefficients of 3 species-pairs and negative association coefficients of 3 species-pairs for the Fisher’s exact test were significant.In the Pearson’s correlation coefficient test,the number of species-pairs being significantly positive was 1,while the negative was 12.According to Spearman’s rank correlation coefficient,14 spe-cies-pairs had significant (P<0.05 or P<0.01)correlation,including 13 negative correlation species-pairs and 1 posi-tive correlation speciesGpairs,accounting for 14.29%and 1.1%respectively in the total 91 species-pairs.The interspe-cific relationships of A.argenteum communities were incompact,the element of communities would change while the environment condition alter,the A.argenteum communities were evolving into steady and independent phase.关键词
