Assessment of ecological and economical balance of the territory of Ob-Tom interfluve considering anthropogenic load
Abstract
The relevance of the discussed issue is caused by the need to assess the territory between the rivers Ob and Tom for developing measures of the effective territory use to preserve the natural complex and non-confrontational economic and recreational activities. The main aim of the study is to assess ecological and economic balance of the territory of Ob-Tom interfluve. The methods used in the study: the method of assessment of environmental and economic balance, taking into account the anthropogenic load. For research of a regional object's conditions- a choice as a basis the analysis of structure of lands is submitted to the most adequate. As the land use objectively reflects a current state of industrial, agricultural and recreational impact. The results. The authors offered a classification for Ob-Tom interfluve based on preliminary, expert estimates and the analysis of a current state of different types of land use in the studied territory. A number of specific types of anthropogenic influence were added to the categories which are traditionally used (for example, operation of underground sources of water supply). A comprehensive estimation of ecological and economic balance of the territory of Ob-Tom interfluve was carried out in terms of the main categories of land use, taking into account various degrees of anthropogenic load. The authors analyzed the major negative factors of impact on different sites of the territory, calculated the coefficients of relative and absolute intensity of the territory. The authors also defined the coefficient of natural shielding of the territory and analyzed future tendencies of ecological and economic state changes. The calculations show that the condition of the territory of research at the moment in general can be defined as moderately transformed, but the tendency of strengthening of the negative phenomena is obviously shown - the number of lands under anthropogenic influence is growing.
