physicochemical condition - Opis:
- In the period 2007-2009, floristic, habitat and physico- chemical analysis was made of the hydraulically improved surrounding ditch of Lake Bikcze in the Łęczna-Włodawa Lakeland. Hemicryptophytes, with a large proportion of geophytes as well as hydrophytes and helophytes, were the main component of the flora of the studied section of the transformed Piwonia River channel. In terms of historical-geographical classification, spontaneophytes were predominant, and apophytes among them, whereas anthropophytes were poorly represented, which was confirmed by the correspondingly high values of the synanthropization and apophytization indices (> 50%) as well as the low value of the anthropophytization index (approx. 2%). In the aspect of the range of occurrence, Euro-Siberian and cosmopolitan species were predominant, which are classified in terms of the indicator values as hygrophilous plants, neutral to continentality, living in moderately cool or moderately warm climatic conditions, characterized by a wide range of tolerance to the trophic state index and to soil acidity. An analysis of the values of the basic physico-chemical factors of the stagnant water in the surrounding ditch showed variations in the value of pH, electrolytic conductivity and the value of the concentration of organic and ammonium nitrogen as well as of organic phosphorus and phosphates. In spite of the anthropogenic nature of the studied watercourse, the qualitative and quantitative proportions of the flora species indicated the natural state of the flora based on the native vegetation, characteristic of the study area.
