Knowing and evaluation of landscape as a basis of environment stimulat
es the formulation of research programmes. This contribution suggests
a scope of the subject as given by the theoretico-gnoseological dimens
ion of landscape and problems connected with its complete and correct
statement. Landscape ecology is able to objectivize the statement lean
ing on three aspects - visual, spatial (spatial-temporal) and ecosyste
m, especially in applied landscape research. Research programmes of la
ndscape synthesis respected the mentioned aspects and moved forth the
degree of knowing of landscape through evaluation of landscape potenti
als for the realization of social functions. A solution to particular
intentions and environmental impact assessment resulted in a formulati
on of procedures for environmental planning.
