  The properties of the light vector meson states around 2.0 GeV have been
poorly understood for a long time, which has become a barrier to the expansion
to higher light vector meson spectrum. Recently, the BESIII collaboration
released the measurements of the $e^+ e^- \to \omega\pi^0$ and $e^+ e^- \to
\rho\eta^{\prime}$ reactions above 2.0 GeV, both of which are ideal processes
to study the isovector $\rho$ meson family. In this work, through carrying out
a combined analysis of the Born cross section data for the above two processes
with the theoretical support on mass spectrum, and production and strong decay
behaviors of the $\rho$ meson family around 2.0 GeV, we identify the
enhancement structure near 2034 MeV observed in $e^+e^-\to\omega\pi^0$ to be
the interference contribution from two resonances $\rho(1900)$ and
$\rho(2150)$, and another enhancement structure at 2111 MeV reported in
$e^+e^-\to\rho\eta^{\prime}$ to be the contributions from $\rho(2000)$ and
$\rho(2150)$. This conclusion means that the $e^+e^-\to\omega\pi^0$ and
$e^+e^-\to\rho \eta^{\prime}$ are the excellent golden channels to establish
$\rho(1900)$ and $\rho(2000)$, especially for a $D$-wave state $\rho(2000)$,
whose experimental search in the $e^+e^-$ collision should be quite
challenging. The relevant cross section measurements with higher precision are
expected in the future BESIII and Belle II experiments.
