英文摘要We present optical luminosity functions (LFs) of galaxies in the (0.1)g, (0.1)r, (0.1)i bands, calculated using data in similar to 40 deg(2) sky area of the LAMOST Complete Spectroscopic Survey of Pointing Area (LaCoSSPAr) in the Southern Galactic Cap. Redshifts for galaxies brighter than r = 18.1 were obtained mainly with LAMOST. In each band, LFs derived using both parametric and non-parametric maximum likelihood methods agree well with each other. In the (0.1)r hand, our fitting parameters of the Schechter function are phi(*) = (1.65 +/- 0.36) x 10(-2) h(3) Mpc(-3), M-* = -20.69 +/- 0.06 mag and = -1.12 +/- 0.08, which agree with previous studies. Separate LFs are also derived for emission line galaxies and absorption line galaxies. The LFs of absorption line galaxies show a dip at (0.1)r similar to 18.5 and can be fitted well by a double-Gaussian function, suggesting a bimodality in passive galaxies.
