Ландшафтна структура проектованого національного природного парку «Орільський» у межах Петриківського району Дніпропетровської області

Abstract

The purpose of this study is to analyze and summarize the experience of landscape diversity research within Petrykivsky district of projected national park “Orilskyy”. Scientific substantiation of creating a national park Orilskyy in the Dnipropetrovsk region prepared to order the Department of Environment and Natural Resources of the Dnipropetrovsk Regional State Administration. Due to the remoteness from major industrial centers Oril River can be considered one of the cleanest and least transformed steppe river. Its valley preserved typical and unique landscape complexes in dire need of protection because of the tense ecological situation in the region. Initial assumptions concerning the history of landscape studies of the region are characterized. Comprehensive description of the natural territorial complex national park Orilskyy within Petrykivsky regionis outlined. Route field research to establish the main features of the morphological diversity of landscapes within the entire territory of the planned national park, and also a series of semi-stationary landscape and geo-botanical descriptions of more typical areas highlighted as key were carried out. In the field stage of research, the verification of selected landscape units and their geospatial boundaries was carried out. Landscape diversity within studied area is defined and mapped. As an indicator in the allocation of individual landscape units were used characteristics of the earth's surface - uniform topography and lithological composition of the rocks of the aeration zone, and the same type of vegetation that points to a common origin of selected units. The study found that modern landscape diversity of Petrikivsky district was formed mostly with man-made, and thus energy-dependent types of landscapes that certainly adversely affects the general condition of natural and related systems. Eleven landscape types were allocated within studied area. All variety of selected landscape units can be divided into two groups. The first group includes natural and semi-natural landscapes, presented within the floodplain and the first terrace of Oril valley. The second large group includes man-made landscapes, which are largely dependent from the man because of disability of keeping environmental sustainability and energy-dependence. Developed maps illustrate in detail the nature of the landscape differentiation and can serve as a basis for future more detailed facies mapping, used as a basis for all future research in the area of the park, as well as for the development and implementation of environmental policies and programs, tourism management, etc. The results represent the internal differences within the area that will develop the optimal structure of nature within the study area, maintain and increase its landscape diversity.
