The Influence of Geotextiles Stabilizing the Soil on Vegetation of Post-Excavation Slopes and Drainage Ditches

The paper presents preliminary results of the studies concerning influence of geotextiles stabilizing the soil on vegetation of post-excavation slopes and drainage ditches. Analyzed anthropogenic habitats are situated in Międzyrzecze and Nieboczowy (Silesian Province, Southhern Poland). They have been previously subjected to reclamation treatment, consisting in installation of wool and synthetic geotextiles in the ground. The studies on plant community were conducted according to commonly applied Braun-Blanquet approach. Recorded phytocenosis were classified into Molinio-Arrhenatheretea R. Tx.1937 and Stellarietea mediae R. Tx., Lohm. et Prsg.1950 class. For comparison of plant patches growing on two variants of geotextiles Hierarchical Cluster Analysis was used. Moreover, the number of species (S), Shannon-Wiener index (H), evenness index (J) and average heights of herbal layer were calculated. It has been shown, that the type of geotextiles has a slight influence on the variability of investigated plant patches. However, relatively high differences in total coverage and mean height of herbal layer between plots protected and unprotected were observed. It shows that the geotextiles support the process of natural ecological succession on habitats with high inclination, mainly through water retention and reduction of erosion.

W pracy przedstawiono koncepcję wykorzystania spontanicznych zbiorowisk roślinnych w architekturze krajobrazu, zwłaszcza jako formę zastępczą dla trawników w mieście. Omówiono zalety asocjacji i ich pozytywny wpływ na środowisko. Do zbiorowisk predestynowanych do zastosowania w projektowaniu terenów zieleni należą: zbiorowiska synantropijne (klasy: Stellarietea mediae, Artemisietea uulgaris i Agropyretea inter mediorepentis), murawy psammofilne (klasa Koelerio glaucae-Corynephoretea canescentis) oraz zbiorowiska łąkowe (klasa Molinio-Arrhenatheretea).

The paper presents the conception of spontaneous plant communities usage in landscape architecture, especially as a substitute to lawns in the city area. Advantages of such associations and their positive influence on environment are presented. They contribute to the such site's conditions improvement as soil, water and air conditions. They do not need a lot of maintenance and it is less expensive than the maintenance of common lawns. They are more resistant to hard city conditions than ornarnental plants. Moreover they often have several decorative values. The communities predestined to use in green areas designing are: synanthropic communities (class Stellarietea mediae, class Artemisietea oulgaris and Agropyretea intermedio-repentis), dry grasslands (class Koelerio glaucae-Corynephoretea canescentis) and dry meadows communities (class Molinio-Arrhenatheretea).
