Studying of Plants Populations in the Conditions of Industrial Pollution in the Neighborhood of the Cities of the Karaganda Region

Abstract

Objective In the article the results of studying of structure of plant populations are given in the neighborhood of the industrial cities of Temirtau, Balkhash, Zhezkazgan and in adjacent territories. Methods Field researches were conducted route-recognostic and semiportable methods. For each vegetable community established full floristic structure, determined phases of phenological development of separate species, their vital state, abundance (by a scale of Drudae), placement, morphometric parameters (height, development). Population density was estimated on the basis of data on a projective covering of vegetation. The age structure of communities we studied with application of methodological recommendations of R. Rabotnov. Reference of plants to this or that age state - based on a complex of qualitative morphological features the fresh and herbarizated plants. Results It has defined that round the industrial cities there is a loss longterm long vegetative elements, the share the ruderal grassy oneyear elements increases. Conclusion The carried-out analysis of a ratio a bio morph showed considerable changes and in the ratio trees, bushes, semi-low shrubs, grassy perennials and annual and biennial plants
