  The spectral observations and analysis for the W80 Region are presented by
using the data of Medium-Resolution Spectroscopic Survey of Nebulae (MRS-N)
with the Large Sky Area Multi-Object Fiber Spectroscopy Telescope (LAMOST). A
total of 2982 high-quality nebular spectra have been obtained in the 20 square
degree field of view (FoV) which covers the W80 complex, and the largest sample
of spectral data have been established for the first time. The relative
intensities, radial velocities (RVs), and Full Widths at Half Maximum (FWHMs)
are measured with the high spectral resolution of LAMOST MRS, for H$\alpha$
$\lambda$ 6563 \AA, [\ion{N}{ii}] $\lambda$$\lambda$ 6548 \AA, 6584 \AA \ , and
[\ion{S}{ii}] $\lambda$$\lambda$ 6716 \AA, 6731 \AA \ emission lines. In the
field of view of whole W80 Region, the strongest line emissions are found to be
consistent with the bright nebulae, NGC 7000, IC 5070, and LBN 391, and weak
line emissions also truly exist in the Middle Region, where no bright nebulae
are detected by the wide-band optical observations. The large-scale spectral
observations to the W80 Region reveal the systematic spatial variations of RVs
and FWHMs, and several unique structural features. A 'curved feature' to the
east of the NGC 7000, and a 'jet feature' to the west of the LBN 391 are
detected to be showing with larger radial velocities. A 'wider FWHM region' is
identified in the eastern part of the NGC 7000. The variations of [\ion{S}{ii}]
/ H${\alpha}$ ratios display a gradient from southwest to northeast in the NGC
7000 region, and manifest a ring shape around the 'W80 bubble' ionized by an
O-type star in the L935. Further spectral and multi-band observations are
guaranteed to investigate in detail the structural features.
