The article deals with the experience of modeling morpholithogenic basics of landscapes (so called «geotopes» - sites) and elementary watershed by means of geographic information systems. The ultimate goal of modeling is to identify potential areas of valuable forests within the poorly-studied of Russian Far East territories. The basic stages of simulation procedure are: delianation of regions with a monotonous manifestation of the landscape generating factors, plotting raster image for the main factors of landscape differentiation such as - level above the nearest watercourse, slope, aspect, slope position, topographical index. Principles of morphological and functional combination of two natural matrices - matrix landscape locations and the matrix of elementary catchments are denoted. The article provides a brief theoretical justification of the proposed algorithm and describes the basic stages of modeling, questions for discussion and perspectives for further optimization as well.
