摘　　要：以鄱阳湖自然保护区为研究对象,通过构建植被群落-水文参数直方图和计算敏感性指数,分析植被群落对水文条件变化的耐受性和敏感性,研究湿地植被群落与水文情势的关系。结果表明,在鄱阳湖自然保护区内,不同的植被群落对水文情势变化的耐受性和敏感性不同,苔草群落、假俭草群落对水文条件变化敏感性较低;苔草-廖子草群落、苔草-虉草群落和虉草-苔草群落对水文条件变化的敏感性较高,喜欢相对湿润的环境;南荻群落所能承受的水文条件变化范围较窄,喜欢相对干旱的环境。We link the hydrological processes with the vegetation distribution across the Poyang Lake national nature reserve by creating histograms and calculating sensitivity index. Results show that the vegetation community types re- act differently to the hydrological conditions within the Poyang Lake national nature reserve. Specially, some commu- nities like Carex community and Eremochloa ophiuroides community are able to tolerate a wide variety of mean water depth and percent time inundated, while other communities like Carex-Polygonum criopolitanum community, Carex- Phalaris arundinacea community and Phalaris arundinacea-Carex community could be found at locations with a rela- tively narrow range of hydrological conditions and they desire more humid environments. The Triarrhena lutarioriparia community is predominantly at more xeric environments. We suggest that these results would provide a new insight for evaluation of hydro-engineering projects on vegetation communities and wetland vegetation restoration.
