The integrated research on the soil cover of the geosystemic territorial units as base for landscape evolution forecast and the environment protection

The investigation of territory for the purpose of its developing and managing implies both an ecosystemic and geosystemic research. The geoecological approach, that combines the two aspects, contributes to a better knowledge of the interrelation between the environment and the human community as well as between the organisms and their biotop, correlated with the continuous intensification of the anthropic activity impact. The manner of geoecological characterization of the geosystemic territorial unit is presented (fig. 1 and 2); the geoecological approach of the geosystem components is more comprehensive, especially from the integrating point of view and functional relations. The soil cover being an essential component of the geosystemic unit (integrating and reflecting both the factors, conditions, quality state and evolution of this unit), a special attention was paid to the soil and its properties at the characterization of the geosystemic unit (considering the soil as subsystem of the geosystem and ecosystem). The steady state of the geosystemic unit is conditioned by a continuous irreversible flux of matter and energy through this unit. The evolution forecast of the geosystemic unit is based on the examination of the components change, fluxes and specific processes as well as on the balances of water, chemical elements and organic matter; on this base, the consequences and the changes of the geosystemic unit parameters are evaluated and the new state of the geosystemic unit is estimated. Only a well-integrated characterization of the geosystemic territorial units can assure a more adequate evaluation of the state, potential and plasticity of the geosystemic unit, a more proper forecast of the geosystemic unit changes and a correct strategy of harmonizing the more intensive land use and industry development with the suitable requirements and measures for the natural resources conservation (including amelioration and/or regeneration) and for the environment protection. The development of the geoecological researches on the geosystemic territorial units is very necessary and useful. Also is very useful to carry out some experiments in territorial polygons and to model the specific processes for different geosystemic units.
