Revealing principles of inundable ecosystem dynamics and formation mechanism of its stable conditions is the main aspect for providing natural system functioning that gives a possibility correctly and effectively make visual environment reaction appraisal on forcing natural and anthropogenic impact. Taking into account that land cover has a specific high rate of challenge response on dynamic changes in inundable-deltoid visual environment, viability to conduct geobotanical monitoring increases the results of which can be used for series of measures development for making more optimum territory natural resources potential use, as well as for visual environment stable functioning and biodiversity increase. Analysis results of repeated geobotanical observations (1961, 1973, 2010) in transect and indices plots in the southern part of Volgo-Akhtubinskoi plain are presented in this work. It is established that the greatest land cover xerophytization and its pasture degradation in this part of the plain was in 1973.
