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.
