Space photos facilitate the compilation of
maps with spatial distribution of securing
stands and linear erosion network, the de
termination (with the probability of 0.7-
0.9) of their shape, geometric parameters,
construction and species groups. Selective
vertical and oblique aerial photography at
scale 1:3000 and 1:5000 makes it possible
to determine the species composition in se
curing stands, their age, mean height and
diameter, number of trees, volume per 1 ha
with mean-root-square errors of +5-157. which
is satisfactory in practice (Borovikov, Ka
satkin & Sidorenko 1985).
Hence, in complex study of forest develop
ment and reproduction dynamics with the help
of materials of aerial and space photography
by the principle: 'from the general to the
particular' the three-stage (space, aerial,
ground) system of information collection in
which the next stage details and specifies
information obtained with the help of the
previous stage may be successfully used. Fi
eld work in the forest when solving all the
tasks of the given group is necessary only
for studying the interpretational features
and aerial and space photography materials,
for accomplishing of the control and speci
fication of the interpretation results. As
a result the timeliness of work increases,
it becomes less labour consuming, and it's
cost is reduced 1.5-2 times and more.
The obtained timely information about the
results of anthropogenic activities in the
forest allows to eliminate or reduce their
unfavourable consequences, and to actualize
the studied forest fund materials in time.
