In this paper we study the sensitivity of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) project for the determination of cosmological parameters, employing the Monte Carlo Markov chains method. For comparison, we first analyze the constraints on cosmological parameters from current observational data, including those from the Wilkinson Microwave Anisotropy Probe, Sloan Digital Sky Survey and SNIa (type Ia supernovae). We then simulate the 3D matter power spectrum data expected from LAMOST, together with the simulated cosmic microwave background data for PLANCK and the SNIa data from the five-year Supernovae Legacy Survey. With the simulated data, we investigate the future improvement of cosmological parameter constraints, emphasizing the role of LAMOST. Our results show the potential of LAMOST in probing for the cosmological parameters, especially in constraining the equation of state of the dark energy and the neutrino mass.
