living organism) <strong>and</strong> the antropogenic (social work). They endure the dynamics ofcoomon geo-system physical expressed by a particular type of l<strong>and</strong>scape.Often, the dynamics of a component element may be different from al thedynamics <strong>and</strong> then, changing relationships between components, requires a newdynamic trend expressed by altering the l<strong>and</strong>scape. Geo-systems may evolvebetween the three states defining: the biological exploitation (relationship betweencomponents imbalance caused by natural causes or anthropogenic), anthropogenic(imbalance relationship between constituents <strong>and</strong> the relationships among thesehaving an artificial effect by anthropogenic activities) respectively ecological support(balance between relations support the operation of biological <strong>and</strong> ecological stabilityof morphology-structural components), they cause environmental degradationsupport <strong>and</strong> /or biological exploitation, effects are forwarding, then each otherbetween all the components.Was conducted a wide study of the <strong>Danube</strong> plains as well as on each of itsnatural units <strong>and</strong> were thus distinguished 13 areas, namely:-Natural Unit Turnu Severin – Gruia- Natural Unit II Gruia - Calafat- Natural Unit III Calafat – Jiu- Natural Unit IV Jiu – Corabia- Natural Unit V Corabia – Olt- Natural Unit VI Olt – Zimnicea- Natural Unit VII Zimnicea – Pietrosani- Natural Unit VIII Pietrosani – Giurgiu- Natural Unit IX Giurgiu – Arges- Natural Unit X Arges – Calarasi- Natural Unit XI Calarasi – Harsova- Natural Unit XII Ialomita – Siret- Natural Unit XIII Siret – Ceatal IsmailAnalyses carried out allowed the identification of areas in biostazie (phase ofstability in l<strong>and</strong>scape evolution due to absence of erosion, where there is avegetation layer) present all over the unbanked <strong>Danube</strong> floodplain; areas inrhehistazy that are represented by urban / rural areas; areas in parastazy (instabilityin l<strong>and</strong>scape evolution due to erosion in the absence of a permanent vegetationlayer) - characteristic for agriculture areas.
