The correction of Hawking temperature of Schwarzschild-de Sitter (SdS) black\nhole is investigated using the generalized Klein-Gordon equation and the\ngeneralized Dirac equation by taking the quantum gravity effects into account.\nWe derive the corrected Hawking temperatures for scalar particles and fermions\ncrossing the event horizon. The quantum gravity effects prevent the rise of\ntemperature in the SdS black hole. Besides correction of Hawking temperature,\nthe Hawking radiation of SdS black hole is also investigated using massive\nparticles tunneling method. By considering self gravitation effect of the\nemitted particles and the space time background to be dynamical, it is also\nshown that the tunneling rate is related to the change of Bekenstein-Hawking\nentropy and small correction term (1+2\β m2). If the energy and the\nangular momentum are taken to be conserved, the derived emission spectrum\ndeviates from the pure thermal spectrum. This result gives a correction to the\nHawking radiation and is also in agreement with the result of Parikh and\nWilczek.\n
