Landscape methods of air-space data interpretation
All-Union ’Lesprojekt’ Association, Moscow, USSR
The landscape methods for air-space data in
terpretation are based on the concept, that
the Earth*s geosphere is the system of na
tural territorial complexes (PTK). PTK are
historically established and dimensionally
Isolated unities of five basic interacting
and interconditioned nature components: li-
thogenic basis (earth*s crust), atmosphere,
water, flora and fauna, developing under the
guiding influence of the llthogenic basis*
PTK are understood as any complete consist
ing of five components natural unities inde
pendently on their complexity; continents,
geographical countries, regions, districts,
landscapes, terrains, stows, facies* PTK are
separated from each other by objectively
existing natural borders and they are cha
racterized by the morphological structure,
that is by the natural combination and inner
distribution of repeated PTK of lower rank,
which are smaller and simpler in structure
and which are genetically and dynamically
conjugated* PTK are relatively homogeneous
in age, history of their formation (genesis),
dynamic trends of their development, morpho
logical structure and ecological regimes*
PTK are revealed on the basis of their li-
thogenic base community in the range of re
lief shapes, their elements, tectonic struc
tures, etc*
The principle aims of the landscape met
hods for air-space data interpretation are:
revealing PTK, studying their genesis, mor
phological structure, ecology, natural bor
ders along with the simultaneous ecologo-ge-
netic and applied classification of the re
vealed units*
The essence of the structural and analytic
method for forest interpretation is the com
mon use of the most general features of lan
dscape when analysing the PTK structure by
air-space photographs* The most important
are nine features (they are enumerated in
succession of co-ordination) i*e* genetic
unity; age homogeneity from big to small
units; contingency of components; leading
role of llthogenic base features; territori
al contingency of natural components; coin
cidence of components borders; recurrence
(rhythmics) and its regularities; specific
features of different natural complexes stru
cture; similarity of the structure of units
which are genetically and dynamically simi
lar (See Diagram 1)*
Concrete recommendations and approaches
to revealing natural complexes, i*e* neces
sity of the analysis and use of genetic and
dynamic rows, study of contingency and recu
rrence of natural complexes, method for keys
of different scales, method of landscape in
dicators and other more particular methods
and approaches logically follow from the
said landscape features*
The use of landscape natural features for
forest interpretation considerably enlarges
the volume of diagnostic features and land
scape indicators and allows to implement ad
ditional mutual control of interpretation
