Abstract: LAMOST is a large-field-of-view multi-object spectroscopic telescope located at the Xinglong Observatory in China. It currently has the largest low-resolution spectral database in the world. Its geographic location determines that it can observe declination-declining sky regions above -10 degrees. LAMOST is a powerful facility which can provide ground support for space missions, including observations of variable stars and eclipsing binaries in the K2-C1 field (Ra:11:35:46, Dec: 01:25:02). We identified and calibrated 355 variable stellar parameters using LAMOST DR3 data. The effective temperature error of calibrated giant stars and dwarf stars is approximately 131K and 104K, respectively. The surface gravity acceleration error is around 0.19dex and 0.16dex, the metal abundance error is 0.15dex and 0.10dex, and this data accuracy will promote research on the variable stars of the K2-C1 sky area.
