This study aims to highlight relations emerging between vegetal organisms and water factor. The water input in an ecosystem is realized mainly by: precipitations, water vapors from the atmosphere, fog, dew, underground water, snow melting, springs, river flooding, high flow. The water losses from the ecosystem come from evaporation, transpiration and infiltration down to depths inaccessible to plants. In delineating the relations emerging between plants and the water environment, the roots system has an important ...

The present study aims to highlight the importance of the vegetal organisms, in restoring the natural balance, based on field research. The vegetal layer under its multiple aspects and the complex processes taking place in its framework, as well as its relations with the environmental factors, constitute an essential element in the natural circuit of the environment and a basic component of the geographic layer, indispensable for a complete characterization and understanding of the structure and dynamics of terres...
