Санкт-Петербурга в зависимости от заданных параметров водной среды (глубины, содержания общего фосфора, рН и удельной электропроводности). Применение многомерной статистики (канонического анализа соответствий) позволило выявить закономерности распределения видов диатомей в городских водоемов. Установлены количественно выраженные экологические предпочтения основных таксонов.</p></abstract><trans-abstract xml:lang="en"><p>The paper discusses the results of the study of surface-sediment diatom species – environment relationships in the water bodies of St. Petersburg city. Application of canonical correspondence analysis (CCA) enabled establishing a relationship between the diatom assemblages composition and water depth, total phosphorus, pH and specific conductivity. Ecological preferences of main diatom species have been established as well.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>диатомовые комплексы</kwd><kwd>городские водоемы</kwd><kwd>гидрохимия</kwd><kwd>канонический анализ соответствий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>surface-sediment diatoms</kwd><kwd>urban ponds</kwd><kwd>hydrochemistry</kwd><kwd>canonical correspondence analysis</kwd><kwd>St. Petersburg.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Автор признателен сотрудникам лаборатории гидрохимии ИНОЗ РАН к.г.н.
