Assessment of the ecological condition of the Ilyinets impact structure environment

Abstract

The article summarizes information about the Ilyinets structure exclusiveness, highlights its geological, mineralogical and geochemical, landscape and historical and cultural features. This topic relevance is due to the issues of preserving land resources within the cosmogenic landscape and assessing the state of the environment. The assessment of the ecological state of the study area made it possible to outline the threats to the environment within the Ilyinets crater. Among the natural origin threats, exogenous processes (geological work of surface waters, wind erosion, weathering) stand out, as a result of which ravines and gullies are formed; there is soil degradation, landscape changes and the like. Anthropogenic pressure carries two types of threats: unintentional actions to cause harm; and willful harm. The anthropogenic activity sometimes coincides with natural processes, raising their harmful consequences. In the work, stresses, critical, supercritical and catastrophic states of the environment of the Ilyinets impact structure are indicated. The characteristics and ranking of environmental threats are presented. The data obtained allow us to represent the ecological state of the Ilyinets crater as close to supercritical. We consider the administrative approach to the geological natural monuments allocation to be the main problem of the Ilyinets impact structure preservation. In order to stop the deterioration of the ecological state and preserve the unique natural structure, soils, landscapes and biogeodiversity of the territory, it is proposed to create the Ilyinets National Natural Park together with the existing botanical reserves, since increased ravine formation and intensive agricultural activities will lead to the land and forest resources degradation, impoverishment of biodiversity, as well as the loss of the recreational and tourist attractiveness of the region as a whole.
