Аннотация

The article gives the results of experimental and estimated researches on ascertainment of ecological
factors’ impact on the condition of mausoleum of Khoja Ahmed Yasawi. Main types of anthropogenic sources,
existing near historical monument area were detected. Chemically polluted precipitation was determined as the main
source of air pollution, generated due to burning of fossil fuel, tires and various waste, accumulation of domestic,
construction and other production wastes, transport emissions. It was ascertained that black dust, greenhouse and
ozone depleting gas, aerosols of acid, salt, hydrocarbon and its derivatives, heavy metals constitute a special hazard
for conservation of mausoleum and its facilities. Vegetation, especially a locust tree was selected for creation of
barrier on the spread of corrosive dust and gas mixtures as absorbents. It is planted along conservation zone border.
We developed the understratum of new composition to plant the locust tree due to absence of fertile layer in the
nekrozem. It represents a mixture of mass. %: vermitea (20), sawdust (20), grey perlite containing waste (5), wood
ash (1), the rest is sierozem (nekrozem).
