Secondary successions of grass vegetation on the right bank of the river Ob (Altai Territory)

摘要

The secondary succession of grass vegetation on the right bank of the river Ob (Altai territory) was investigated. The analysis has shown that the successions go in 3 hypothetical rows, depending on the humidity of ecotopes: ‘xerophytic’, ‘mesophytic’, ‘mesohydrophytic’. It is obvious that the rate of succession slows down in the conditions of more arid ecotopes. The dynamics of the aboveground phytomass are generally subject to this trend. The higher the succession rate, the quicker the phytomass develops.
