Using　the　158　sets　of　strong　ground　motion　recordings　obtained　from　the　National　Strong　Motion　Observation　Network　System　(NSMONS)　of　China　and　the　Local　Earthquake　Early　Waring　Network　of　Yunnan　Province,　we　analyse　the　characteristics　of　observed　near-field　strong　ground　motion　amplitude,　acceleration　response　spectra　and　the　spatial　distribution　of　spectral　accelerations　at　different　periods　for　the　M36.4　Yangbi　earthquake.　The　spectral　accelerations　of　the　near-field　stations　were　compared　with　the　NGA-West2　prediction　models,　and　the　on-site　earthquake　damage　investigation　results　were　combined　to　verify　the　directivity　effect　of　the　nearfield　strong　ground　motion　of　the　n6.　4　Yangbi　earthquake.　The　research　results　show　that　the　peak　ground　acceleration　(PGA)　within　30　km　in　the　near-field　shows　a　difference　in　directionality　from　north-south　(NS)　to　east-west　(EW),　and　the　maximum　difference　in　PGA　is　1.　86　times;　The　spectral　accelerations　near　the　predominant　period　of　the　horizontal　acceleration　response　spectra　(SA)　are　generally　higher　than　the　basic　design　spectra.　The　SA　corresponding　to　the　predominant　period　in　the　NS　direction　of　53YBX　station　is　3.　87　times　the　value　of　the　rare　design　spectra　platform;　The　spatial　distribution　contours　show　that　the　horizontal　SAs　observed　in　the　rupture　forward　(　south-east　of　epicenter)　are　significantly　larger　than　that　in　the　rupture　backward,　which　is　more　obvious　in　a　short　period,　and　the　difference　gradually　decreases　with　the　increase　of　the　period;　The　short-period　SAs　observed　in　the　rupture　forward　is　greater　than　the　median　predictions　of　four　NGA-West2　prediction　models,　while　the　SAs　observed　in　the　rupture　backward　is　smaller　than　the　median　predictions　of　four　NGA-West2　prediction　models　throughout　the　period,　showing　a　significant　directivity　effect;　The　earthquake　damage　investigation　results　also　show　that　the　damage　of　buildings　in　the　near-field　shows　a　more　severe　directivity　difference　in　NS　direction　than　EW　direction.
