Continental inland saline wetlands are among the most endangered habitats in Europe. In the Danube-Tisza-Danube canal network (Serbia, Southeastern Europe), which is one of the largest canal networks on the continent, the rare and endangered inland saline wetland Bolboschoenus maritimus community (BMC) has been found at only two locations. Two vegetation types of the community have been identified: (i) with Bolboschoenus maritimus and Marsilea quadrifolia (BMC-M) dominance and (ii) with Bolboschoenus maritimus and Butomus umbellatus (BMC-B) dominance. The aim of the study was to compare the habitats of the ascertained vegetation types in terms of 55 water and soil properties that influence their development, floristic composition and differentiation. The main properties influencing the community development and differentiation were water alkalinity, chemical oxygen demand, CO₃²⁻, water pH, soil conductivity, K⁺ and Ca²⁺ content in the soil. Both vegetation types grow in non-saline, slightly alkaline, nutrient-rich habitats with eutrophic water. When compared to BMC-B, BMC-M was found on heavy clay soils with higher conductivity, CaCO₃, humus, nutrients, macroelements, and Na⁺ content, in shallower water with higher suspended solids and oxygen content, lower contents of nutrients, dissolved salts, HCO₃⁻, macroelements, conductivity, and alkalinity. The study provides new data on the BMC distribution in this part of Europe and the first detailed information on its habitat conditions. Thirty-one species from the European Red List of Threatened Species were found in the stands. These results may be useful when deciding on the appropriate preservation measures aimed to rehabilitate other wetland habitats and biodiversity.

东南欧稀有和濒临灭绝的内陆盐沼湿地群落的评估，其具有欧洲白桦（Bolboschoenus maritimus（L.）Palla）优势：水物理化学性质的影响

大陆内陆盐渍湿地是欧洲最濒危的生境之一。在非洲大陆上最大的运河网络之一的多瑙河-蒂萨-多瑙河运河网络中，仅在两个地方发现了稀有且濒临灭绝的内陆盐渍湿地湿地Bolboschoenus maritimus群落（BMC）。已经确定了该社区的两种植被类型：（i ）占主导地位的Boboboschoenus maritimus和Marsilea quadrifolia（BMC-M），以及（ii）占主导地位的Boboschoenus maritimus和Butomus umbellatus（BMC-B）统治地位。该研究的目的是从影响其发育，植物组成和分化的55种水和土壤特性方面比较确定的植被类型的生境。影响群落发育和分化的主要特性是水的碱度，化学需氧量，CO ₃ ^2-，水的pH值，土壤电导率，土壤中的K ⁺和Ca ²⁺含量。两种植被类型都在非盐碱，略带碱性，营养丰富且有富营养化的栖息地中生长。与BMC-B相比，BMC-M被发现在电导率，CaCO ₃，腐殖质，养分，常量元素和Na ⁺较高的重粘土上内容，在较浅水具有更高的悬浮固体和氧含量，营养物含量低，溶解的盐，HCO ₃ ^- ，大量元素，电导率和碱度。该研究提供了有关欧洲该地区BMC分布的新数据，以及有关其栖息地条件的首个详细信息。在林分中发现了31种来自“欧洲受威胁物种红色名录”的物种。在确定旨在恢复其他湿地生境和生物多样性的适当保护措施时，这些结果可能会有用。
