  We study a sample of 119 Herbig Ae/Be stars in the Galactic anti-center
direction using the spectroscopic data from Large sky Area Multi-Object fiber
Spectroscopic Telescope (LAMOST) survey program. Emission lines of hydrogen
belonging to the Balmer and Paschen series, and metallic lines of species such
as FeII, OI, CaII triplet are identified. A moderate correlation is observed
between the emission strengths of H$\alpha$ and FeII 5169 \r{A}, suggesting a
possible common emission region for FeII lines and one of the components of
H$\alpha$. We explored a technique for the extinction correction of the HAeBe
stars using diffuse interstellar bands present in the spectrum. We estimated
the stellar parameters such as age and mass of these HAeBe stars, which are
found to be in the range 0.1 -- 10 Myr and 1.5 -- 10 $M_{\odot}$, respectively.
We found that the mass accretion rate of the HAeBe stars in the Galactic
anti-center direction follows the relation $\dot{M}_{acc}$ $\propto$
$M_{*}^{3.12^{+0.21}_{-0.34}}$, which is similar to the relation derived for
HAeBe stars in other regions of the Galaxy. The mass accretion rate of HAeBe
stars is found to have a functional form of $\dot{M}_{acc} \propto t^{-1.1 \pm
0.2}$ with age, in agreement with previous studies.
