Zhytska L. Herb covring of urbans ystems as indicator of edaphotopes state and atmospheric pollutions ( at the examples of city of Cherkassy)

Results of complex ecological assessment of the edaphotopes, phytocenosis and atmospheric conditions of Cherkassy urban systems with phytoindication usage are represented in the theses. Directions of phytoindication researches of Ukrainian urban systems conditions have been analysed in the work, characteristics of the natural and anthropogenic factors of the cherkassy urbagenic environment impacts are represented and principle ecological factors of the urban systems optimization for vegetation coverage of urban edatopes are marked out as well. On the basis of physico-chemical, toxicological, phytoindicated and other environmental indexes of the state of edaphotopes, zoning of territory of city is conducted. In the process of edatopes, leaves of indicator kinds of trees and Lichens Flora investigation conclusions have been made as for pollutants impact increasing and their accumulation in the objects of research - edaphotopes, atmosphere, and vegetation. Maps are drawn up as to distribution of synantropical flora associations; anthropogenic edatopes transformation; and Lichenoindication map that represents levels of the atmospheric environment pollution of the city Cherkassy. Priority directions phytoindicated investigations and also recommendations concerning guality edaphotopes indexes improvement and the city's urban Flora development will be used under the nature conservation actions and for environment situation control in the region and in the system of urban environment optimization.
