Danylyk R. Ecological and biological characteristic of the vegetation of water ecosystems of L'viv green zone (transformation, phytoindication, restoration)

Object - water ecosystems of L'viv complex green zone (CGZ). The aim is - realization of an ecological estimation of hydrophilic plant cover and finding - out of its ecological-biological features and phytoindication properties, establishment of a hemeroby's degree and revealing of the ways of optimization autotrophical block hydroecosystem of L'viv CGZ. Methods - standard rather - morphological and ecological-floristical technique, methods of phytoindication and hemeroby. It was established the composition of hydrophilic plant cover and it was carried out its structural analysis. It was made the analysis of hydrophilic vegetation of L'viv CGZ and it was elucidated their ecological and phytocoenosis role in formation and functioning of the plant cover on the base of ecological and floristic classification. It has been determined biomorphological structure according to the S. Heine classification for hydrophilic flora of L'viv CGZ; ecological analysis was carried out using G. Ellenberg's scales. It was estimated water quality of model units of L'viv CGZ according to the hydrophysical, hydrochemical and quantitative indices of hydrophilic plant cover, and it has been made mathematic interpretation of mutual dependence between researched parameters. It has been carried out an assessment of hemeroby levels of hydrophilic plants and it has been made a complex characteristic of hydroecosystems of researched territory. Spheres of use are the rational use and protection hydroecosystem, training courses.
