Research was based on the method of retrospective photointerpretative analysis of land use froms [20] using aerial photographs taken in 2007, as well as satellite images from Rapid Eye taken in 2009. The photographs were converted to the from of an orthophotomap, with one pixel representing 0.5 m in the field. Maps of actual structure of land use and surface measurements of individual precipitation were made using GIS software (Arcview, ArcInfo). Besides that, ecological valorization also was based on the following criteria : surface of small water bodies their shape, origin,length of shoreline,the presence of a buffer zone as scrub and reed communities, diversity, and land use around them.
