Роль макрофитов в формировании гидрохимического режима водотоков водно-болотных угодий Нижней Волги

Роль макрофитов в формировании гидрохимического режима водотоков водно-болотных угодий Нижней Волги

Abstract

Water-marsh lands of the Lower Volga are considered to be the most preserved in Europe. Their originality is conditioned, first of all, by a wonderful species diversity. Water-marsh lands of the Lower Volga are subjected to intensive anthropogenic influence particularly caused by the sewage disposal. However, in the Delta of the Volga River in consequence of intensive processes of natural purification the factors of the contamination are considerably low. This is due to the increase of macrovegetation in the Delta. The capacity of high water plants, in particular reed and reed mace, to accumulate, utilize and transform many substances of the water body makes them irreplaceable in the general process of natural purification of water bodies in the Volga delta.

Водно-болотные угодья Нижней Волги считаются наиболее сохранившимися в Европе. Их уникальность обусловлена в первую очередь необыкновенным видовым разнообразием. Водно-болотные угодья Нижней Волги подвергаются интенсивному антропогенному воздействию, связанному в первую очередь со сбросом сточных вод. Однако в дельте р. Волги, вследствие интенсивных процессов самоочищения, показатели загрязнения значительно ниже. Это обусловлено зарастаемостью дельты водными макрофитами. Способность высших водных растений, в частности тростника и рогоза, к накоплению, утилизации и трансформации многих веществ, содержащихся в водном объекте, делает их незаменимыми в общем процессе самоочищения водоемов дельты р. Волги. Библиогр. 4. Ил. 2.
