The secend year observation mission of the LAMOST regular survey launched on September, 2013, and have been already successfully accomplished on Jule ,2014 under the joint effort of entire staffs of the center for operation and development of Guoshoujing telescope. Totally, over 1.3 million spectra with signal to noise larger than 10 of 725 sky area are obtained during the past year, which sufficiently demonstrate the advantage of LAMOST in spectra accessing. The data set of LAMOST data release two (DR2), including spectra of the pilot survey and spectra of the past two years of the regular spectroscopic survey, have already published to domestic data users and foreign partners. The DR2 totally contains 4,136,482 spectra, including 909,520 spectra of pilot survey and 3,226,962 spectra of regular survey. In addition, we calculate the atmospheric parameters of 2,207,788 stars, which becomes the largest stellar spectral parameters catalog in the world at present.
