  freshwater swamp
officinalis is a freshwater swamp species that when occurring in association with mangroves occupies low-salinity soil microsites, or alternatively that it possesses mechanisms preventing accumulation of salt in photosynthetic tissues.
      
In this study, we determined the effects of the 1997-1998 ENSO-related drought on the hydrology and salinity of a Micronesian mangrove ecosystem and an adjacent freshwater swamp.
      
At the peak of the drought (February 1998), the most dramatic result was a reversal in groundwater flow that sent groundwater from the mangroves upstream toward the freshwater swamp.
      
An undescribed ascomycete similar to species in the Aliquandostipitaceae (Jahnulales, Dothideomycetes) was collected from submerged wood in a freshwater swamp in Big Cypress National Preserve, Florida.
      
Most of these lowlands were originally peatswamp forest, freshwater swamp forest and mangrove.

Based upon invetigation of boring core in Zhenjiang, apical area in Yangtze delta, the Holocene transgression is dated between 9000 and 6300 years B.P., when sea level was located at 10—12m. and 2—3m. below the present Woosung level respectively. Since 6300 years in area of Zhenjiang boring deposited sediments of freshwater marsh, so it seems in Yangtze delta aea no sea level was higher than present one during 5000—6000 years B.P.

根据长江三角洲顶部镇江地区钻孔岩蕊的研究,全新世海水影响该地的时间为距今9000—6300年间,当时海面分別位于吴淞零点以下10—12米;2—3米。6300年以来镇江钻孔所在地区沉积淡水沼泽沉积,因此,5000—6000年前长江三角洲地区似无高于现今的海平面。

The modern stromatolitic material studied in this paper was collected from supratidal freshwater marshs in NW Andros Island, Bahamas by Cao R. in 1983. It was here that the phenomenon of ecological relationship between laminated stromatolites and soft algal heads is quite clear (Fig. 2).

作名从生物学和岩石学角度研究巴哈马安德罗斯岛西北部潮上淡水沼泽区采集的现代叠层石,获以下几点认识:1.藻碳酸盐沉积物既与不同类型的藻类有关,又与不同环境有牵连;2.碳酸盐叠层石日生长层在成岩期间会被强烈改造;3.一些蓝绿藻能富集镁,形成高镁方解石,较易于白云石化;4.粘捕碳酸盐颗粒和原地沉淀碳酸盐晶体都是叠层石的重要成因;5.构成叠层石的藻类的降解作用在叠层石堆积过程中不间断地进行,所以藻碳酸盐岩中的这些生物难于保存为化石。

Four different ecotypes of reeds——fresh water swamp reed,salty water swamp reed,lower salt meadow reed and higher salt meadow reed were investigated in the Yellow River Delta.The growth status,composition and dominance of reed community were observed,and the organic and inorganic osmotica,osmotic potential and osmotic adjustment ability were determined.Results are as follows:The abundance,coverage,plant height,leaf water content and osmotic potential all decrease with the increasing salinity levels of habitats.Potassium and soluble sugars are the main osmotica of reeds in lower salinity,while Na + and Cl - are the main osmotica in higher salinity.Na + content of roots is higher than that in leaves,and the osmotic adjustment ability of roots is higher than that of leaves.Na +/K + ratio of plants changes with the salinity of environments,with a value of about 1 in higher salinity.Moreover,the contributions of osmotica to the osmotic adjustment change with the salinity of the habitats,the higher the salinity leael,the more the contributions of inorganic osmotica,but the less the contributions of organic osmotica.The above results show that Phragmites communis, might be a pseudohalophyte.

山东省黄河三角洲分布4种不同生态型芦苇——淡水沼泽芦苇、咸水沼泽芦苇、低盐草甸芦苇和高盐草甸芦苇。1994年与1995年的8~9月份对不同生境生态型芦苇的生长情况、群落组成及优势度进行观测,并测定4种不同生态型芦苇的有机和无机渗透剂以及渗透势和渗透调节能力。结果表明:不同生态型芦苇的多度、盖度、植株高度、叶片含水量和渗透势均随生境盐度的增大而降低;低盐度下的芦苇其渗透剂以K+和可溶性糖为主,高盐度下以Na+、Cl-为主;芦苇根部Na+含量大于叶片,其渗透调节能力也高于叶片;植物体的Na/K比值随生境盐度而变化,而高盐度下Na/K比为1左右;在渗透调节中有机和无机渗透剂的贡献随生境盐度而变化,有机渗透剂贡献随生境盐度增大而减少,无机渗透剂贡献则随盐度增加而增大。上述结果证明芦苇是一种应性较强的植物,从抗盐机理考虑可以认为它是一种假盐生植物。
