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 nonwovens 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.

TX。,LOHM。 et prsg.1950类。为了比较在土工织物分层分析的两个变体上生长的植物斑块。此外,计算了物种数量,香农 - 维纳指数(h),均匀度指数(j)和草药层的平均高度。已经表明,土工织物的类型对研究的植物贴片的可变性感到轻微影响。然而,观察到保护和不受保护的地块之间的总覆盖和草药层的总覆盖和平均高度的相对较高的差异。它表明,土工织物支持具有高倾角的栖息地的自然生态继承过程,主要是通过水保留和减少侵蚀。
