Abstract
The results of studies of the dynamics of productivity, photosynthetically active radiation, and evapotranspiration according to Terra MODIS data for five test plots in the near-channel part of the floodplains of the Kargy River (glycophyte, swampy, and natural meadows), as well as willow stands along the banks of the Mugur River, are presented. An analysis of long-term changes in meadow vegetation in the study area from 2000 to 2021 showed a general positive trend in gross productivity and differences between communities. Against the background of an increase in actual evapotranspiration (by 43%), the potential evapotranspiration decreases (by 10%), which indicates the drying up of the study area. Seasonal maxima of meadow productivity were observed in 2014, 2016 and 2020-2021. The years 2001, 2003-2004, and 2009 turned out to be critical for meadow vegetation. A weak positive correlation was found between the gross productivity of vegetation and the evapotranspiration of the territory and a stronger one with photosynthetically active radiation. The seasonal dynamics of productivity corresponded to the meadow type of vegetation.
