Relations between morphometric and trophic parameters of shallow lakes of the Polish Lowland
Summary.

Majority of Polish lakes are shallow lakes, which constitutes about 60% of the total number and gather significant volume of water. Shallow lakes situated in lowlands are often susceptible to eutrophication and degradation due to influence of different factors, e.g. soil type, high density of human population and several types of human activities. Also other factors, such as lake morphometry, altitude and watershed area also influence lake ecosystem. Lakes selected to examination were characterised by altitude up to 200 m a.s.l., maximum depth up to 10 m, mean depth up to 5 m and accessible information about concentration of trophic parameters. Data used in analyses such as Secchi depth, concentration of total phosphorus, dry mass of seston and chlorophyll a, lake and watershed area, lake morphometry were collected mostly from public statistics edited by National Inspectorate for Environment Protection (PIOŚ) for years 1982-1993 and from own surveys for years 1997-2000. Statistical comparisons were made for seven morphometric and four trophic parameters. Significant linear correlations between chlorophyll a, dry mass of seston and Secchi depth and morphometric parameters were found. In case of the studied shallow lakes both the depth of water and lake water area play an important role in establishing the level of water trophy, whilst influence of Schindler coefficient is negligible. A complex impact of morphometric parameters was assessed using CCA method. Results showed, that the most diverse trophic parameter was Secchi depth, which depended on average depth, maximum depth of lake water and altitude.
