ECOSYSTEM APPROACH FOR EVALUATING DEGRADATION PROCESSES AND NATURE PROTECTION IN INNER ASIA

https://doi.org/10.24057/2071-9388-2010-3-2-66-77

Abstract

he paper presents results of eco-biological assessment of Inner Asian ecosystems using the example of Mongolia as a case study. The comprehensive environmental analysis of changes in Mongolia’s environment included approaches based on three principles: (1) formal, (2) administrative division, and (3) landscape-ecological. We analyzed ecosystems that have undergone at last three levels of alterations (moderate, heavy, and very heavy) due to anthropogenic factors. Based on our analysis of degradation processes that result in heavy and very heavy anthropogenic alteration of the natural environment, we isolated 5 groups of hazardous degradation processes: (1) rangeland overgrowth with shrubs, (2) deforestation of forest-steppe ecosystems, (3) desertification of ecosystems on light soils, (4) depletion of ecosystems of hydromorphic landscapes, and (5) narcotization of agrocenoses in modified ecosystems. The comprehensive assessment of adverse changes of natural habitats has enabled a revision of the state policy for the organization of the optimum network of wildlife reserves for conservation of floristic and faunistic diversity.
