    The description of the forest phytocenoses was based on 69 phytosociological records taken in the areas of coniferous habitats and forest habitats. They were taken deep in the forest situated about 80 to 100 m from the car park (typical forest communities) and in the area of 1 to 10 m in width, adjacent to the car park (ecotone zone). The phytosociological records were also taken in the area of mid forest car parks. The aim of the studies is to determine types of communities and their structure (floristic composition, phytosociological stability (S) and cover coefficients (D) of species). Deep in the forest, in coniferous habitats (mainly in the mixed fresh forest) dominant are the patches of Leucobyro-Pinetum association, of Pomeranian-Silesian variety with a distinguishing taxon Deschampsia flexuosa. In the habitats of the mixed fresh forest the most numerous are the phytocenoses of the birch-oak forest (Betulo pendulae-Quercetum roboris), and as to the fresh forest, the most numerous is the community of fertile beech forest of Pomeranian type (Galio odorati-Fagetum). Communities within the ecotone zone are charecterised by partial rebuilding of the structure. The same communities as those in the ecotone zone are found deep in the forest, but there are more species of seminatural and synanthropic communities. Phytocenoses in car parks have a completely different structure. In the fresh coniferous habitats and in the mixed fresh coniferous habitats, patches of Sieglingio-Agrostietum alliance are observed, a part of which was classified as suballiance S.-A. poëtosum annuae. In fertile forest habitats, dominant are mainly patches of carpet community Lolio-Polygonetum arenastri, with a considerable contribution of the communities of Molinio-Arrhenatheretea, Artemisietea and Stellarietea mediae classes. It was also observed that the forest communities within the forest habitats are poorer floristically in comparison with phytocenoses of forest habitats. The richest floristically communities are the ones within the zone in which a car park is adjacent to the forest.

    Struktura geograficzno-historyczna flory oraz jej stopień synantropizacji w fitocenozach leśnych przylegających do parkingów oraz występujących w ich obrębie

    Changes in the flora of natural forest communities forming in the areas between the forest and a roadside car park or the forest and a forest car park and in the phytocenoses of car parks were determined by enumerating anthropogenic indices of: natural character of flora, proper synanthropy and potential flora, proper and potential apophytization, proper and potential apophytism of spontaneophytes, general anthropophytisation, archeophytization of flora, kenophytization of flora, modernization of flora (M), stability of the flora of anthropophytes and stability of total flora and the indices of fluctuation changes in the flora of anthropophytes and in total flora of the studied phytocenoses. Communities deep in the forest in both habitats are characterised by considerably larger indices of natural character, as compared to the flora of phytocenoses of the area between the forest and the car park. The lowest natural character is shown by communities in the car parks. Whereas phytocenoses formed in the car parks show the highest indices of proper and potential synanthropization. This is the result of anthropogenic impact on these specific habitats. A direct penetration of the habitats of the forest adjacent to the car parks (ecotone zone) by travellers leads to a change in the structure of phytocenoses towards their synanthropization. This is confirmed by the indices of anthropophytisation, which are largest in the communities of the car parks. In the structure of the investigated communities, the contribution of archeophytes is small and in the phytocenoses of the forests they are not found at all. The occurrence of alien species (kenophytes) in the studied phytocenoses is not significant and this is confirmed by small indices of kenophytization. The flora of the examined communities shows a high degree of stability and fluctuation changes in anthropophytes and the entire flora of individual phytocenoses are not big. Only in phytocenoses in the car parks in the forest habitats, the index is a little larger due to the occurrence in them a larger number of diaphytes. The analysis of the spatial structure of anthropogenic indices of variability in the flora is of considerable cognitive significance. It facilitates verification of the space from the perspective of the natural character of the flora (the index of the natural character, synanthropization and apophytization) and also the expansion of alien species (the index of kenophytization and fluctuation changes). It also allows to determine the relative stability of the species composition (index of archeophytization and stability of the flora).
