АГРОВИРОБНИЦТВО ЯК ФАКТОР РОЗПОВСЮДЖЕННЯ АДВЕНТИВНИХ ВИДІВ РОСЛИН НА ТЕРИТОРІЇ ВОЛИНСЬКОГО ПОЛІССЯ

The article analyzes the role of agricultural production in the distribution of alien species. It has been established that agricultural production is one of the important factors in the distribution of alien species due to its pecularities; since over 60% of the adventiv species found on the territory of the Volyn Polissya is associated with agricultural land. There are also given the study results of systematic, bioecological, arealogical, florogenetic structures of the adventiv species that are found within the agricultural lands. The investigated species character and methods of dis-tribution, their phytocoenotic role, peculiarities of scattering across drained systems are considered as well. It was esteblished that among the registered alien plant species, the ratio of archeophytes and kenofites is approximately the same with a slight predominance of the first ones; the vast majority of the Volyn Polissya adventiv flora species, growing on agricultural lands, originate from the arid and subarid regions of the planet; one-year grass plants or terophytes predominate in the spectrum of life forms of detected stranger species; most of the non-aboriginal plant species that grow on agricultural lands are well adapted to the proliferation and the spread of their diasporas. It is concluded that, despite the widespread distribution of most adventiv flora species, only some of them exhibit a significant phytocoenotic role in the groups of cultivated crops. The results of the study provide the ground for asserting that more than 40% of the total species composition of the Volyn Polissya adventiv flora fraction given for agricultural land is presented on the territory of drainage systems.
