In this article, an anthropogenic influence on natural
ecosystem such as an excavation of sand is discussed.
Investigations were done in Kuyar Forest District of
the Mari El Republic on a sandpit. The adjacent plot
of natural forest was taken as a control. For evaluation
the degree of environment transformation as a result of
sand excavation several indicators were used. As
indicators of physical soil degradation - thickness of
organogenic horizon and soil density; for assessment a
chemical degradation – content of main nutrients and
humus; as an indicator of biological degradation – the
level of active microbial biomass. Besides, a potential
phytotoxicity was estimated. The study proved:
physical and chemical parameters corresponded with
the fourth degree of soil degradation, at the same time,
biological parameters approximated to parameters of
soil from natural territory
Human-induced disturbance on water objects was appraised with chemo and biological methods, the results of which are turned out to be comparable
