The optimal forage agrocenose, in which the steadiness for extremal environmental factors cobined with the high productivity and energetic effectiveness of photosynthesis and their self-regulation and self-sustaining, has been created in the Lower Don region. The influense of the mosaic horisontal structures of the formation of the productivity functions and the cenotic regime, has been studied both by experimentally and by simulation techniques in the ecological laboratory of the Botanic Garden (Rostov-on-Don University). The dynamics of plant communities in the experimental agrocenoses with different structures has beenclassified as an autogenic succession of the syngenetic type with elements of endoecogenesis. It is shown that the control over the longevity of the productive stage of syngenesis is possible. Only in forage stage the high formation of living phytomass and the close-up of sward are possible due to the elimination Ambrosia artemisifolia of the population of the grass and legumes.
