  The correction of Hawking temperature of Schwarzschild-de Sitter (SdS) black
hole is investigated using the generalized Klein-Gordon equation and the
generalized Dirac equation by taking the quantum gravity effects into account.
We derive the corrected Hawking temperatures for scalar particles and fermions
crossing the event horizon. The quantum gravity effects prevent the rise of
temperature in the SdS black hole. Besides correction of Hawking temperature,
the Hawking radiation of SdS black hole is also investigated using massive
particles tunneling method. By considering self gravitation effect of the
emitted particles and the space time background to be dynamical, it is also
shown that the tunneling rate is related to the change of Bekenstein-Hawking
entropy and small correction term $(1+2\beta m^2)$. If the energy and the
angular momentum are taken to be conserved, the derived emission spectrum
deviates from the pure thermal spectrum. This result gives a correction to the
Hawking radiation and is also in agreement with the result of Parikh and
Wilczek.
