INVASION PROCESSES IN PLANT COMMUNITIES IN THE ASPECT OF THE LANDSCAPE ANTHROPOGENIZATION

Nadezhda Ivanisova

Abstract

The study of ways and means of introducing adventive vegetation species into the of steppe zone landscapes ecosystems is an important aspect in the processes of temporal and spatial landscapes transformation study. Natural anthropogenic landscapes are artificial systems created based on the zonal vegetation natural framework but at the same time supported by humans. Often, native species of vegetation are replaced in the anthropogenization process and are replaced by species that are not the area characteristic. Indigenous species have their development trends, which are adjusted by the optimum of natural and anthropogenic factors. With a critical change in one of them, the entire community instability arises and at this moment invaders enter and invasion processes appear. It is necessary to observe the ecological niches filling of artificially created plant communities and to regulate the processes of adventive species extremely intensive introduction. Invasive plant species that inhabit the steppe communities have many specific properties that provoke allergic reactions, which can lead to serious consequences for human health. This aspect exacerbates the ecological situation in large cities and large industrial centres, where any additional adverse factor can greatly affect public health, especially if invasive species are found in residential and forest-park landscapes.
