Abstract
The properties of solutions to a degenerate parabolic system with nonlocal sources
which subject to nonlocal Dirichlet boundary conditions
were considered.By using comparison principle and the upper-lower solution method
the conditions for the global existence and the finite blow-up of solution to the system are established.The solution of system has different properties when the exponential satisfied different conditions.
