湖泊生物区系基本上是由湖泊流域的水文形态特征所决定的，建立湖泊类型学是湖泊质量评价和管理的第一步。根据描述符变量（大小、深度、湖床物质、水情和大型植物覆盖度），潘诺尼亚生态区建立了16种水文形态湖泊类型。我们的分析表明，描述变量对浮游植物的生物量和组成有相当大的影响。由于几种湖泊类型的浮游植物生物量可以合并，可以提出一个简化的类型学。由于浮游植物组成的各种湖泊类型的多样性和相对丰度的功能群方面显着不同，以及划定的组合物为基础的类型不能建立潘诺尼亚湖。虽然潘诺尼亚生态区是欧亚草原带的最西部，建议的类型学研究领域可以扩展到大潘诺尼亚地区的湖泊。
As lake biota are basically determined by hydromorphological characteristics of the lake basin, establishment of a lake typology is the first step in lake quality assessment and management. Based on descriptor variables (size, depth, lake bed material, water-regime and macrophyte coverage), 16 hydromorphological lake-types were established for the Pannonian Ecoregion. Our analyses revealed that descriptor variables have considerable effect both on biomass and composition of phytoplankton. As the phytoplankton biomass of several lake-types can be merged, a simplified typology can be proposed. Since the phytoplankton composition of various lake-types differed significantly in terms of diversity and relative abundance of functional groups, well delineated composition-based types cannot be established for Pannonian lakes. Although the Pannonian Ecoregion is the westernmost part of the Eurasian steppe zone, the proposed typology of the studied area can be extended to lakes of the greater Pannonian region.
