The main idea of this publication is the approach to the expert estimation of the urban
environment with the help of ecological indices of indicator plants being part of the urban flora of
Donetsk. The working block-scheme of this project realization consists in the analysis of the plants
according to the types of survival in an industrial city while realizing vital strategies.
We suggest the following phyto-indices which range as follows for Donetsk according to a
preliminary estimation:
• correlation of violents, patients and explerents (in the model variant 2 : 6 : 1),
• reproductive capacity of explerents (23-45 c.u.),
• reproductive capacity of patients (58-90 c.u.),
• reproductive effort of indicator plants (19-26),
• reproductive success of indicator plants among patients (20-27),
• demographic full value of patients (availability of all vital forms),
• structural plasticity of species of plants on the level of organ morphology (approaching to
normal distribution),
• structural plasticity of species of plants according to histological distinctions (tissue
deformations, mostly conformational functionally active tissues),
• percentage of species with wide ecological amplitude (no less than 45),
• percentage of species having formed strategies of adaptation to air pollution (no less than
35),
• percentage of species having formed adaptation to soil and water and soil solution pollution
(no less than 60).
Such a botanical and ecological approach together with current activities on technical
monitoring of the state of industrial environment in the Donetsk city will enable to estimate the
ecological misbalance and the extent of ecotopes disturbance more correctly. So far, it's the biota
that has that very informative index of living organisms' reaction to additional anthropogenic
pressure.
