[8] Within Caraorman sand bank, due to reduced fertility of the sandy soil there a good correlation between the area occupied by the soils component and plants associations. If in addition to indicator species for the soil hydric characteristics we will use indicator species for other characteristics of the soils will be obtain a matrix of the soils characteristic state states. Within the plant associations and soil component, any change in the distribution and frequency of indicator species provides a quick indication of the soil evolution. Ihus the appearance of species characteristic of a particular plant association in the other associations in the bordering area between the two is an indication of soil evolution (which there are two associations) and the direction in which it will do (if are changes: humidity, pH, texture, quantity of humus, salinity, etc.). According to the data presented in this paper, the hydric characteristics of the soils in the Caraorman sand bank area these are within the optimum parameters for the in the studied soils units. 46
