Принципы и подходы к оценке антропогенного нарушения культур фитоценозов в урбанизированных экосистемах

Abstract

There were suggested principles, criteria and indicators of diagnostics of anthropogenic transformation of urbo-ecosystems at the levels of change detection: organ, plant, taxon (species), biogroup (flower garden-ornamental plants; phytopathogenic complex; consortic links «pathogen-flower gardenornamental plants»); phytocenosis cultures, urbo-ecosystem. There was developed method of synecological determination of character and indirect estimation of the degree of phytocenosis cultures disturbance by the spread of phytopathogenic mycobiota, change of the consortic linkages «pathogenflower garden-ornamental plants». The technique is based on the dependence of the species, systematic and trophic structure and development of the phytopathogenic complex on changes in the environment condition and structure of substrates, biotopes of disturbed phytocenosis cultures in the conditions of recreation and anthropogenic factors. There was substantiated the species composition of phytopathogenic mycobiota, which can be used for myco-indication: anthropogenic, especially recreational disturbance of flower graden phytocenosis cultures.
