  We theoretically study electromagnetically induced transparency (EIT) in
reflection spectra of V-type system at the gas-solid interface. In addition to
a narrow dip arising from the EIT effect, we find the other particular
saturation effect induced by pump field, which does not exist in $\Lambda$ or
$\Xi$ -type system reflection spectra. The saturation effect only induces an
intensity decrement in the reflection spectra, and there is no influence on the
narrow dip arising from the EIT effect. We detailedly calculate and analyze the
dependence of V-type system reflection spectra on probe field intensity, pump
field intensity, coherent decay rate, and the initial population after the
collision between atoms and the interface.
