'Galactic diffuse gamma ray emission (GDE) is introduced by the galactic cosmic rays interacting with the interstellar medium and/or radiation fields. We report the measurements of the GDE in several regions of the Galactic plane with energies ranging from 10 to 100TeV by the half-array of LHAASO-KM2A. A modified equal-zenith angle method is employed for background estimation, in which the known gamma-ray sources have been carefully extracted. The energy spectrum of GDE is obtained by using the forward-folding method. The LHAASO results will help to understand the propagation of cosmic rays in the Galaxy.'
