  The Hawking radiation of BTZ black hole is investigated based on generalized
uncertainty principle effect by using Hamilton-Jacobi method and Dirac
equation. The tunneling probability and the Hawking temperature of the spin-1/2
particles of the BTZ black hole are investigated using modified Dirac equation
based on the GUP. The modified Hawking temperature for fermion crossing the
back hole horizon includes the mass parameter of the black hole, angular
momentum, energy and also outgoing mass of the emitted particle. Besides,
considering the effect of GUP into account, the modified Hawking radiation of
massless particle from a BTZ black hole is investigated using Damour and
Ruffini method, tortoise coordinate transformation and modified Klein-Gordon
equation. The relation between the modified Hawking temperature obtained by
using Damour-Ruffini method and the energy of the emitted particle is derived.
The original Hawking temperature is also recovered in the absence of quantum
gravity effect.
