Khodosovtseva Y. Lichen indication of air quality in urban landscapes of the Yalta amphitheatre

Dissertation is devoted to the lichen indication estimation of the atmospheric air quality in Yalta amphitheatre urbanized landscapes. The list epiphytic lichens, ecological features and distributions of the species within urbanized landscapes of the Yalta amphitheatre are given. The bioindicators figures of 134 species of lichens in conditions of the Mediterranean climate on south coast of Crimea are proposed in the first time. It is suggested to select the indicators of air quality as high, background, middle and low quality of atmospheric air, which correlate with the synergetic influence of the anthropogenic and natural factors. These groups include bioindicators of the separate parameters of the atmospheric air as indicators of the acid or basic air pollution. It is suggested to use bioindicators of the climate conditions of the atmospheric air and it is selected lichen biondicators of the subtropical Mediterranean climate. This species are widespread in recreation landscapes on a southeast and south-west parts of the Yalta amphitheatre. The map with six isotoxic lichen indication zones is created. The temperate clean estimation of the atmospheric air quality in the urbanized landscapes of the Yalta amphitheatre are provided. The complex research of indicator lichen groups distributing and lichen indication zones is carried out in selitebe, recreate and transport landscapes, The high relative air quality is observed in the recreate landscapes of the south-west and east parts of Yalta urbanized landscapes. It territories are located in the lichen indication zones of high cleanness and have a most percent of the high and background air quality indicators. Low air quality both after lichen indication zonation and distributing of air quality indicators it is observed in the central part of the Yalta town.
