We　compare　and　analyze　the　consistency　of　observed　acceleration　and　velocity　data　recorded　by　accelerometer　and　seismometer　simultaneously　in　five　aspects:　time　series,　5%　damped　response　spectra,　the　variation　and　distribution　characteristics　of　peak　value　ratios　and　spectral　acceleration　ratios,　and　correlation　analysis.　The　results　show　that　these　two　have　good　consistency,　especially　in　medium-frequency　bands　and　medium-　and　far-fields.　In　the　research　dataset　of　ground　motion　prediction　equations　(GMPEs),　we　propose　the　weight　ratios　of　the　observed　acceleration　and　velocity　records　and　verify　that　the　empirical　weighted　ratios　are　reasonable　and　reliable　and　applicable　to　southwest　China.
