We calculated the CP averaged branching ratios and CP-violating asymmetries of two-body charmless hadronic Bs->PP,PV decays with the QCDF approach, including the contributions from the chirally enhanced power corrections and weak annihilations. Only several decay modes, such as Bs -> K^(*)K, K^(*{\pm}){\pi}^{\mp}, K^{\pm}{\rho}^{\mp}, {\eta}^('){\eta}^('), have large branching ratios, which may be observed in the near future. The penguin-to-tree ratio P_{\pi \pi}/T_{\pi \pi} and a bound on angle ${\gamma}$ are given.
