Сlassification of the urban ecotopes with the connection of the study of sinanthropy (at the example of the city Orekhovo-Zuevo, Moscow region)

The aim of this work is the search for evaluation criteria of synanthropic properties of the individual species in the context of their ecological distribution. The use of the term ecotopes is discussed in the article. The possibility of the use of terms that nominate the communities, not only in phytocenosis, but also in ecological aspect is described. According to the degree of anthropogenic degradation there are three categories ofecotopes which were grouped in five rows on the main influencing anthropogenic factors affecting the change in soil cover. On the basis of the selected series linear-cluster classification of anthropogenically transformed ecotopes is developed and its advantage in comparison with hierarchical classifications is discussed. Ecotopes identified during the floristic research on the territory of Orekhovo-Zuevo were the basis for the construction of this classification. The authors propose the possibility of using this classification in the study of synanthropic properties of the species. Four groups of species according to the degree of synanthropy depending on the affinity to the categories of the ecotopes: non synanthropic, relatively synanthropic, facultative synanthropic, obligate synanthropic are distinquished.
