ABSTRACT:
The extending of mine areas in the Russian North leads to increase of technological
influence on environment. As a result there occurs transformations of Tundra and Taiga
Ecosystems which may be irreversible. Therefore monitoring is needed to control the
development of negative processes. Realization of monitoring is maximum effected on
basis of Remote Sensed Data (RSD). RSD allows to make follows : 1) to record and to
analyze the types intensity, relationships of different influences on environment with
enough accuracy and quickness over large areas; 2) to predict trends of Ecosystems
development to finish future by analysis of the Earth's space image obtaining at
different times. RSD are based on system approach to environmental monitoring as they
imagine the decreasing spatial model of Earth's surface for depicted on their territory.
The scale row of RSD provides possibility of diverse level ecosystems studying.
Knowledge acquisition and aero-space and geological-landscape data are formed to
provide complex investigations. They are basis of Integrated Geographical Information
Systems which allows to operate and analyze various information. Dynamic of Tundra
and Taiga Ecosystems influenced from of large metallurgical and mine enterprises is
observed on example of sites in the Western Siberia and the Kolsky Peninsular.
natural environment at the Norilsk area
are: 1) activity of the powerful Norilsky
integrated mining and metallurgical plant
1. THE NORILSK AREA
At present natural environment of the
Norilsk area is subjected to intensive
anthropogenic forces. The result of this
influence is the natural landscape distur-
bance, Which makes bad ecological situa-
tion for living organisms and vegetation.
The technogenic influence leads to de-
struction of surface covers, disturbance
of thermal region of thawing layers in
different seasons, the intensive develop-
ment of bad cryogenic phisical/geological
processes, Which proceeds very slowly in
ordinary conditions.
The main Sources of technogenic forces to
for extraction and refining of mineral
resources; 2) landscape transformations
due to launching of Khantaiskaya hydro-
electric power station and filling of reser-
voir which was not prepared to flooding.
This fact led to rotting of flooded vegeta-
tion and to increase of fenol contents in the
water.
Gas and smoke erruptions of Norilsky
mining and metallurgical plant play the
vital importance for creation of bad eco-
logical situation. These erruptions contain
compounds of oxygen and hydrogen with
