| Abstract: | Percentage co-occurrence (PC), point correlation coefficient (PCC), association coefficient (AC), X2 and Pearson r formulaes are used to measure interconnection among 5 communities of desert shrubs in west erdos plateau. Based on the measured results of interspecific association, the distribution character of shrub species and their differences of requirement to habitat were elaborated. The results are significant for researching desert vegetation, which are based on the relationships of population. |
