The article presents methodical aspects of vegetation state assessment with ecological and biotopie evaluation of vegetation preconditioning in suburban zone on the example o f ecophysiographic study for Raszynka catchment area up to Dawidy profile. The area is characterized by agrarian landscape with environmentally disadvantageous land use. Arabie lands dominate in almost entire area, whereas forests and meadows cover very smali part. For several years, surface of settlement area have been inereasing at the cost of fields. At the basis of existing and potential vegetation maps high spatial plant communities diversification have been shown. The highest vegetation structure complexity and the lowest transformation level have been observed for forests on dunes in the south part of the catchment area as well as for plantings and meadows in the Raszynka valley. The plan communities are sensitive for antropopressure. Nevertheless, there are conditions to modify the existing communities, which can help to introduce positive changes in environment and landscape of the Raszynka catchment area.
