| 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。

| Abstract: | 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 react differently to the hydrological conditions within the Poyang Lake national nature reserve. Specially, some communities 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 relatively 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. |
