  We firstly derive the stellar population properties: age and metallicity for
$\sim$ 43,000 low redshift galaxies in the seventh data release (DR7) of the
Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey,
which have no spectroscopic observations in the Sloan Digital Sky Survey(SDSS).
We employ a fitting procedure based on the small-scale features of galaxy
spectra so as to avoid possible biases from the uncertain flux calibration of
the LAMOST spectroscopy. We show that our algorithm can successfully recover
the average age and metallicity of the stellar populations of galaxies down to
signal-to-noise$\geq$5 through testing on both mock galaxies and real galaxies
comprising LAMOST and their SDSS counterparts. We provide a catalogue of the
age and metallicity for $\sim$ 43,000 LAMOST galaxies online. As a
demonstration of the scientific application of this catalogue, we present the
Holmberg effect on both age and metallicity of a sample of galaxies in galaxy
pairs.
