摘　　要：In theγ-ray sky,the highest fluxes come from Galactic sources:supernova remnants(SNRs),pulsars and pulsar wind nebulae,star forming regions,binaries and micro-quasars,giant molecular clouds,Galactic center,and the large extended area around the Galactic plane.The radiation mechanisms ofγ-ray emission and the physics of the emitting particles,such as the origin,acceleration,and propagation,are of very high astrophysical significance.A variety of theoretical models have been suggested for the relevant physics,and emission with energies E≥10^(14) eV are expected to be crucial in testing them.In particular,this energy band is a direct window to test at which maximum energy a particle can be accelerated in the Galactic sources and whether the most probable source candidates such as Galactic center and SNRs are“PeVatrons”.Designed aiming at the very high energy(VHE,>100 GeV)observation,LHAASO will be a very powerful instrument in these astrophysical studies.Over the past decade,great advances have been made in the VHEγ-ray astronomy.More than 170 VHEγ-ray sources have been observed,and among them,42 Galactic sources fall in the LHAASO field-of-view.With a sensitivity of 10 milli-Crab,LHAASO can not only provide accurate spectra for the knownγ-ray sources,but also search for new TeV-PeVγ-ray sources.In the following sub-sections,the observation of all the Galactic sources with LHAASO will be discussed in details.
