Background. Landscape planning is necessary for the development of regional programs of territorial development. Research and scientific study of ecological zones that in one way or another regulate economic activity are the most relevant for determining landscape program in Penza region.
Materials and methods. To develop a model of general scientific map of Penza region we used the synthetic method based on the analysis of deciphered signs of satellite photos, performed with resource satellite Landsat 7 and the use of complex software ERDAS IMAGNE. The starting materials for landscape classification according to their sustainability to chemical attack are cartographic and fund data on geology, geomorphology, hydro-geology and soils of Penza region. The sustainability criteria were developed on the basis of the general principles of the geochemical landscape classification deve¬loped by A. I. Perelman and M. A. Glazovskaya. While developing the model of ecologi-cal framework the methodological experience of the RAS Institute of Geography, MSU named after N. P. Ogarev, Saransk, as well as a database to map the landscape of Penza region were used.
Results. A number of ecological landscape studies in-volving the creation of a general scientific landscape map model, landscape drawing classification, landscape classification based on resistance to anthropogenic impacts, ecological frame model were carried out for landscape planning in Penza region. The landscape map shows the results of typological and regional zoning. Four landscape kinds, 17 locality types and 28 landscape areas are reflected on the landscape map. The main landscape formation processes are exogeodynamic (erosion, suffusion, landslide) ones. According to the sustainability to heavy metal contamination all the landscapes are divided into three groups: 1 – low-sustainable, 2 – medium-sustainable, 3 – the most -sustainable. The most vulnerable are the floodplain and ravine-gully geosystems. The main (regional) ecological equilibrium zones are mixed forests in the basins of the Vada, the Moksha and the left bank of the Sura, stretching from the north to the south. They represent an ecological protec-tion zone of the territory from anthropogenic systems of Central Russia.
Conclusions. The regularities of landscape differentiation justify the development of applied geo-ecological maps. The landscapes of secondary moraine interfluve plains are the most resistant to chemicals. Ecological frame nuclei are the most vulnerable elements of Penza region natural framework. The recommended ecological equilib-rium zones play a major environment-forming role and should not be used in the economic activity.
