Galactic diffuse gamma ray emission (GDE) is introduced by the galactic cosmic rays interacting with the interstellar medium (ISM) and/or radiation fields (ISRF). Studying galactic diffuse TeV gamma-ray emission would help to understand mechanisms of acceleration and propagation of galactic cosmic rays.
LHAASO-KM2A with an large area of 1.36 km2, has an excellent ability to study VHE gamma-ray astronomy and GDE.
In this proceeding, method of background estimation and some techniques to reduce the contaminant of resolved gamma-ray sources are briefly introduced. At last, we look into the inner galactic plane (IGP) and present the measurements.
