Assessment of Landscape-Geoecological Systems with the application of GIS-technologiesE.P. Romanova, A.R. Alyautdinov, M.A. Arshinova Lomonosov Moscow State University, Russia Email: romanova@kmail.ru Landscape-geoecological studies are being actively developed in Russian landscape science. The basic aim is to investigate the results of interactions between natural, economic and social structures at various spatial and time scales. Such works require the use of modern GIS-technologies for analysis of particular landscape units. A map ""Landscape-Geoecological Systems of Europe"" at the scale 1:5 Mln has been created at the Lomonosov Moscow State University. The following stages of research have been worked: 1. Elaboration of LGES model. Landscape-geoecological system (LGES) is a natural unit (natural landscape) modified by economic development. LGES is a complex geosystem which develops and functions as a result of interactions between natural, economic, social and management subsystems. 2. Compilation of a series of maps (""Types of Natural Landscapes in Europe"", ""Economic development systems of Europe""). The maps were compiled at the scale of 1: 5 Mln. Totally there are 613 landscape units on the map Present-Day Landscapes of Europe. The legend shows a complex hierarchy of these natural-territorial units. 3. Elaboration of GIS ""LGES of Europe"". A specialized geographical information system (GIS) has been elaborated in order to organize storage and processing of this vast data array. The GIS includes the following sections: a) Cartographic, i.e. computer versions of maps; b) Thematic database - data array of 48000 parameters on nature components, systems of economic development and ecosystem services; c) Conceptual design; d) Results of GIS-technologies realization: systematization and classification of LGES. 4. Investigation of natural-anthropogenic processes in landscapes. These are the processes stimulated by economic activities and they could be of two types: positive (constructive) or negative (destructive). 5. Calculation of these factors for quality assessment of LGES. The GIS was used to compile maps of particular natural-anthropogenic processes (erosion, acidification, pollution etc.) and to create maps of LGES for the territory of Europe and particular European regions.Key words: landscapes, geoecology, assessment.
