Abstract
Hadron Physics Lanzhou Spectrometer (HPLUS) is designed for the study of hadron production and decay from nucleonnucleon interaction in the GeV region. The current formation of HPLUS and the particle identification methods
for three polar angle regions are discussed. The Pluto event generator is applied to simulate the primary reactions on HPLUS， concerning four issues as followed: the agreement on pp elastic scattering angular distribution between Pluto samples and experimental data; the acceptance of charged K mesons in the strangeness production channels for the forward region of HPLUS; the
dependence of the maximum energy of photons and the minimum vertex
angle of two photons on the polar angle; the influence on the mass spectrum of excited states of nucleon with large resonant width from different reconstruction methods. It is proved that the Pluto event generator satisfies the requirements of Monte Carlo simulation for HPLUS.
