Abstract
Landscape-ecological investigations were carried-out within the forest steppe of Northern Mongolia. The site conditions of the partly by agriculture used area of Cagaan Tolgoj at the Lower Orchon (Aimag Selenge) were analysed in seven test areas. Results of soil analysis are given. The evaluation of soil cover and partly vegetation cover was carried-out with special regard, to degradation phaenomena. It is based on field analysis, measurements during the soil survey and the detection of soil degradation parameter with the help of laboratory analysis. Among naturally and land use caused factors of soil status and of the changing conditions within forest steppe and steppe ecosystems, climatic-hygric features and cattle grazing are the most important influences in the study area. Potentials and limits of extended man’s activities were shown for different kinds of land use, such as pasture land, arable land and reaping. The climatic scenario of a long-term increasing temperature was also taken into consideration.
