CHENDES*, SORINA DUMITRU**, C. SIMOTA***National Institute of Hydrology and Water Management**National Research and Development Institute for Soil Science, Agrochemistry andEnvironmental Protection of BucharestKeywords: DTM, landforms, TPI, SRTM, agricultural land-useAbstractThe topographic complexity of hilly terrains and its influence on crop growth and soilenergy and water balance could be described using a comprehensiv system of Agro-Environmental Indicators. These could be very useful in order to develop agriculturalpolitics in hilly regions. The derived parameters are the most helpful, by quatifying thetopography contribution to water redistribution in landscape, the changes in solarradiation received at the Earth's surface, etc. One of them, the index of the landforms isdescribed in this paper, and a test for Bend Subcharpathians unit is performed. It could beused in describing or assessing the variability induced by topography on spatialdistribution of the agricultural land-use types.135
