We have combined LAMOST medium-resolution spectra with TESS 2 minute light curves and extracted over 530,000 spectra and 110,000 light curves from more than 40,000 stars. We have quantified the H{alpha} line intensity in each spectrum and found that 38,659 spectra from 7002 stars exhibited excess H{alpha} emission and that the intensity of stellar chromospheric activity increases with later spectral types. We also discovered that the boundary value between the saturated and unsaturated regions of chromospheric activity for different spectral type stars is around Ro=0.1. By analyzing the TESS light curves, we identified 31,539 flare events from 4120 stars. Through these flare events, we determined that the flare-frequency proportion of stars increases with later spectral types. We have found that the power-law index of the flare-frequency distribution for F-, G-, K-, and M-type stars is around 2.0, while that for A-type stars is 1.3. Additionally, we observed that the amplitude of brightness variations caused by modulation due to starspot coverage (Reff) is positively correlated with both the flare intensity and intensity of chromospheric activity and that the chromospheric activity was generally stronger in flare stars as compared to nonflare stars. We also found that within 300pc, the proportion of chromospherically active stars and flare stars decreases with increasing distance from the Galactic disk. Finally, we discovered six flare events from the H{alpha} variation and estimated their energies. 2025ApJS..276...44S https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/276/44 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to B/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-) IV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019) V/156 : LAMOST DR7 catalogs (Luo+, 2019) IV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021) I/357 : Gaia DR3 Part 3.
