中文摘要	该研究以宁夏西吉震湖滩涂湿地4种典型盐生植物群落作为研究对象,通过野外调查采样,实验室分析,结合经典统计学方法,研究柽柳(Tamarix sp.)、盐角草(Salicornia europaea )、碱蓬(Suaeda glauca )、芦苇(Phragmites australis(矮生型)等4种盐生植物群落多样性格局,分析4种盐生植物群落及湖滩裸地土壤全盐和pH特征,为湿地自然保护区湖滨湿地的保护与恢复提供依据.结果表明:(1)在4种盐生群落斑块中共发现植物26种,藜科、禾本科、菊科分别占植物总数的23.08%、19.23%和19.23%;柽柳群落为盐生灌丛,物种数繁杂;盐角草群落、碱蓬群落和芦苇群落属于盐生草甸.物种组成单调,大多是单优群落斑块;3种盐生草甸群落中优势种的重要值显著高于盐生灌丛中柽柳的重要值(P<0.05)。(2) Margalef丰富度指数、Shannon-wiener指数和Simpson优势度指数均是柽柳群落最大,分别为1.105,1.706和0.552; Pielou均匀度指数为:盐角草群落>芦苇群落>碱蓬群落>柽柳群落,分别为1.166.1.021、0.997和0.813.(3)4种盐生群落类型及湖滩裸地土壤全盐表层(0~10 cm)表聚效应显著(P<0.05);表层土壤全盐依次为湖滩裸地>盐角草群落>碱蓬群落>柽柳群落>芦苇群落,土壤盐度分别在0.44%~0.58%、0.49%~0.53%、0.15%~0.54%,0.27%~0.45%和0.18%~0.39%之间;柽柳群落土壤pH随土层加深依次降低,3种盐生草甸土壤pH随土层加深先迅速增大后基本不变,湖滩裸地pH随土层加深先迅速减小后基本不变。
英文摘要	In this study,we selected the four typical halophyte plant communities of beach-wetland of semi- arid area in the Dangjiacha Wetland Nature Reserve of Xiji,Ningxia to explore diversity patterns of four halophyte plant communities, including Tamarix sp.,Salicornia europaea,Suaeda glauca and Phrag mites australis (dwarf type) and also studied the characteristics of total salt and pH in soil of four halo- phytes communities and bare beach. The main conclusions are as follows: (1) a total of 26 plant species were found among four halophyte communities. Among them, Chenopodiaceae,Gramineae and Composi- tae respectively accounted for 23.08%,19.23% and 19.23% of the total plants. Tamarix sp. community species diversity and the community composition of S. europaea,S. glauca and P. australis are monotonous, mostly monotonous community patches. The important values of the dominant species in the three halophyte communities were significantly higher than those in the saline shrub (P<0.05). The important value of Tamarix sp. community was between 0.13 and 0.54,which was significantly different from that of the three salted meadows (P<0.05). (2) Margalef index,Shannon-wiener index and Simpson index were the largest of Tamarix sp. community,which were 1.105,1.706 and 0.552,respectively. Pielou index is S. europaea > P. australis>S. glauca > Tamarix sp.,namely 1.166,1.021,0.997 and 0.813. (3) The effects of total salt content on the surface layer of the four kinds of halophyte communities and the bare beach were significant (P<0.05). In the surface layer the soil total salt was bare beach>S. europaea community>S. glauca community>Tamarix sp. community>P. australis community, respectively between 0.44%- 0.58%,0.49%0.53%,0.15% 0.54%,0.27% 0.45% and 0.18%-0.39%. The soil pH of Tamarix spp community was decreased with the soil depth. The soil pH of the salted meadow is quickly increased with the soil to deepen, after the basic unchanged. The pH of the bare beach is quickly declined with the soil to deepen, after the basic unchanged.
