“…Because of their shallowness they are characterized by fewer predispositions for self-cleaning (Traczewska, 2012). Water relations in retention reservoirs have undergone a great change, and the factor that fostered a trophic growth was touristic and recreational use of the catchment areas, mainly by development of summer buildings, the creation of beaches or fishing (Michalczyk and Wilgat, 1998;Krukowska and Krukowski, 2012). In the retention tanks there was also an intensive fishery.…”

“…Lake Krasne (51°25ʼ35" N, 22°57ʼ31" E) is the deepest (33 m) and the largest (75.9 ha) of the studied lakes. Length of the shoreline is about 3.6 km, whereas the capacity is 8,180,000 m 2 (Michalczyk and Wilgat, 1998). While the group of retention reservoirs included: 1.…”

The Wieprz-Krzna Canal, built in 1961, is one of the longest in Poland (142 km). Although the drainage construction was intended to revitalize the region of wetlands and peatbogs of the West Polesie, it caused large hydrological changes. Research on catchments of three natural lakes and three retention reservoirs involved cartographic analysis using photointerpretation, as well as the Braun-Blanquet method. In the studied area, between 1939 and 2016 the length of rivers and ditches increased more than three times. Macrophytes covered about 20-27% of the natural lakes water surface, whereas in retention reservoirs the coverage was 12-15.5%. Also a greater diversity of macrophytes occurred in natural lakes. In retention reservoirs it was restricted to only emerged macrophytes.RESUMEN: Diversidad floristica de lagos sujetos a cambios a largo plazo en la red de aguas del Polesia Occidental (Polonia Oriental).El Canal Wieprz-Krzna, construido en 1961, es uno de los más largos de Polonia (142 km). Aunque la construcción del drenaje tenía por objeto revitalizar la región de humedales y turberas de la Polesia Occidental, causó grandes cambios hidrológicos. Las investigaciones sobre captación de tres lagos naturales y tres reservorios de retención involucraron análisis cartográficos con el método de fotointerpretación, así como el método de Braun-Blanquet. En el área estudiada, entre 1939 y 2016 la longitud de ríos y zanjas aumentó más de tres veces. Los macrófitos cubrían alrededor del 20-27% de la superficie del agua de los lagos naturales, mientras que en los reservorios de retención era desde 12 al 15,5%. También se observó una mayor diversidad de macrófitas en lagos naturales. En tanques de retención sólo se restringió a las macrófitas emergidas.REZUMAT: Diversitatea floristică a lacurilor supuse modificărilor pe termen lung în reţeaua hidrografică a Polesiei de vest (estul Poloniei).Canalul Wieprz-Krzna, construit în 1961, este unul dintre cele mai mari din Polonia (142 km lungime). De altfel, realizarea drenării a fost destinată revitalizării regiunii zonelor umede şi a turbăriilor din Polesia de Vest, a provocat schimbări hidrologice mari. Cercetările privind captarea a trei lacuri naturale şi a trei rezervoare de retenţie au implicat analize cartografice utilizând metoda de interpretare a imaginilor -metoda fotointerpretării, precum şi metoda Braun-Blanquet. În aria studiată, între anii 1939 şi 2016 lungimea râurilor şi a canalelor a crescut de mai mult de trei ori. Macrofitele acoperă aproximativ 20-27% din lacurile naturale de suprafaţă, în timp ce în rezervoarele de retenţie între 12 şi 15,5%. De asemenea, o mare diversitate de macrofite este în lacurile naturale. În tancurile de reţinere acestea sunt limitate doar la macrofitele emerse.Unauthenticated Download Date | 5/11/18 2:15 PM
