- We have investigated the process $J/ψ\to {\bar{K}}^0K^+ρ^-$ by taking into account the $S$-wave ${K^*\bar{K}^*}$, $ρω$, and $ρϕ$ final-state interactions, where the scalar meson $a_0(1710)$ is generated. In addition, we also take into account the contributions from the scalar $a_0(980)(\to \bar{K}^0K^+)$ and the intermediate resonances $K_1(1270)^{-}(\to {\bar{K}}^0ρ^-) $ and $K_1(1270)^{0}(\to K^+ρ^-)$. Our results show that, in the ${\bar{K}^0K^+}$ invariant mass distribution, a clear peak structure around 1.8~GeV appears, which could be associated with the scalar $a_0(1710)$, however, no significant structure of the $a_0(980)$ is observed. On the other hand, one can find clear peaks of the $K_1(1270)$ in the ${\bar{K}}^0ρ^-$ and $K^+ρ^-$ invariant mass distributions. The future precise measurement of this process by the BESIII and Belle II Collaborations and the planned Super Tau-Charm Facility (STCF) in the future could shed light on the nature of $a_0(1710)$.
