Senko, A.S. | Lysukho, N.A. | Zubritskij, V.S.
Existent approaches to calculation and mapping of critical loads for nitrogen and sulfur for terrestrial ecosystems in Belarus have been considered. Methods of static condition are under the principle attention. Examples of basic equation used for the calculation of Critical Loads and admissions, resulting from the uniform approach calculations are given. An estimation procedure of exceeding atmospheric precipitation on terrestrial ecosystems is given. In this case according to international standards the last ones are: forestry, grasslands and peatland ecosystems. The use of the adapted method for the analyzed algorithms calculations are shown. For the creation of the National GIS the use of small-scale maps, created on the basis of soil and vegetation maps of 1:1 250 000 scale is more appropriate. All stages of a vector map creation with the description of software support and methods of map-making information treatment are shown, methodological foundations of its construction for regional level were described. The results of Critical Loads calculations obtained by this method are applied to the Belarus Commitments Under the Convention on long-range transboundary air pollution
