Long-term dynamics of the area overgrown by helophytic vegetation in Lake Pskov

This paper presents the results of a spatiotemporal analysis of the dynamics of the overgrowing of helophytes in the water area of Lake Pskov (Pikhva) for the period 1988 to 2017. Using the classification procedure for Landsat satellite images for different years, zones of overgrowing by helophytes...
