Popis: | Small rivers reflect to a considerable extent the general situation in the water-protection zone of the Ivankovo reservoir and make their negative contribution to worsening of water quality. Being the most vulnerable link of the ecosystem, they require some correction (if only from positions not requiring large material expenditures), namely: banning plowing of lands up to the water’s edge and creating small forest strips in the near-channel part of rivers; banning the application of fertilizer on snow in water-protection zones, since in this case a considerable amount of it enters directly into the rivers; monitoring the observance by farm and poultry plant workers of the regime of sanitary zones of water objects, reference being to the impermissibility of the washout of wastes from the territories of these enterprises directly into rivers; banning the grazing of large cattle herds on low and high floodplains, which owing to their territorial limitedness and instability to loads do not withstand such pressure and are brought out of an equilibrium state. |
