  The problem of the physical nature and the cosmological genesis of
Lambda-term is discussed. This problem can't be solved in terms of the current
quantum field theory which operates with Higgs and non-perturbative vacuum
condensates and takes into account the changes of these condensates during
relativistic phase transitions. The problem can't be completely solved also in
terms of the conventional global quantum theory: Wheeler-DeWitt quantum
geometrodynamics does not describe the evolution of the Universe in time (RPT
in particular). We have investigated this problem in the context of energies
density of different vacuum subsystems characteristic scales of which pervaid
all energetic scale of the Universe. At first the phemenological solution of
Lambda-term problem and then the hypothesis about the possible structure of a
new global quantum theory are proposed. The main feature of this theory is the
inreversible evolution of geometry and vacuum condensates in time in the regime
of their selforganization. The transformation of the cosmological constant in
dynamical variable is inevitably.
