Studying the whole climate and soil vegetation and landscape of our country and vegetation factors, allows you to know their relations with the crop with their requirements to environmental conditions. Based on these findings was initiated and perfected crops ecological zoning, zoning means topoclimatelor favorable or plants cultivated on natural conditions in the region researched confrontation with biological requirements of plants to them. Zoning is actually topoclimates biogeographical distribution in those cultures where they have favorable conditions for the formation of a high and stable yields year after year. The ecological zoning respect that basic principle of the ecological optimum, ie, the optimum ratio between crop requirements and ecological factors. Zoning is conditioned by other factors: the general geomorphological the river. The zoning work they have priority crops climatic factors, and only after delimitation of so-called zone "topo-climatic" or topo-climatic maps consider plant factor. Of course the temperature and humidity play a key role in zoning by huge influence on the spread of cultivated vegetation. By studying the topoclimate ensure: increased production, the potential biological and productive crop in a given territory, the stability of crops, climate and soil resource exploitation, identifying environmental potential of a region, held or localities; setting priorities for possible ecological reconstruction of degraded and polluted areas.
