Информативность видов при оценке местообитаний фитоиндикационными методами для северостепных дубрав украины

The correction methods of the species position in a factor space on ecological scales are characterised for the regional phytoindication research by example of the oak wood herbage of Northern Steppe of Ukraine (Dnipropetrovsk region). The variation of the species coordinates in the space of ecological factors is described depending on a community (or elements of landscapes) location. The significant difference between computed regional evaluations of species location coordinates and their location in ecological scales are illustrated too. The obligatoriness of species coordinates correction in the factor space of edaphic factors is substantiated for phytoindication. This correction for climatic factorsis recommended.
