URBAN FLORA OF SHYMKENT AND ITS BIOINDICATIVE ROLE
We have done the analysis of six ecological districts outlined by the complex of technogenic and other ecological factors. By the results of urban fl ora species structure defi nition studies in outlined 6 districts, its bioindicative role in species structure was revealed using conventional Sukachevs methodic. Appropriateness of direct depending of urban fl ora species structure on pollution degree was revealed. Species structure of strongly polluted fi rst district is three times less than species structure of sixth clean district. As pollution increases so urban fl ora species structure decreases. Dependence of species structure abundance on the pollution degree indicates on is bioindicative role, that confi rmed by fl ora analysis, formula of Stugren-Radulescu and other statistic data.
