In the same soil water stress condition, individual biomass of P. australis is more than that of A. calamus. 相同土壤水分胁迫条件下，芦苇单株生物量远大于菖蒲。
No significant difference in the community characteristics of macrobenthos was observed between alien S. alterniflora and native P. australis zones. 外来物种互花米草生境下底栖动物群落特征与土著种芦苇生境下无显著差异。
