PRESENT STATE OF TROPHIC PARAMETERS OF THE MAIN WETLANDS AND DEEP WATERS FROM ROMANIA
Journal Title: Present Environment and Sustainable Development - Year 2010, Vol 4, Issue 4
Abstract
We wanted to emphasize, for each region, river basin and aquatic surface, the quality of the lacustrine waters, in order to use them in different fields of activity as well as a life support for the biologic component. The lakes over the territory of Romania are relatively uniformly distributed in the majority of the physicogeographical regions. A low density is specific to the west, where significant draining works have been done, and the highest density is characteristic to the northeast,with numerous ponds, registered since the 14-15th centuries. Most of the lakes on the Romanian territory, especially those analysed in the present study, are man made. Most of the natural lakes are small and they do not have a special ecologic or economic importance. The analysed lakes, although situated in different physicogeographical conditions, are included, in most cases, in the category of good waters from a qualitative point of view, and eutrophic, mesotrophic and hipertrophic, from a trophic point of view. As a result of the fact that most lakes are man made, it is obvious that they are maintained artificially at this stage. Most of the mountain lakes, or those in the volcanic areas, are ultra-oligotrophic and oligotrophic.
