Qinghai　Province　is　rich　in　tourism　resources,　so　its　tourism　industry　is　developing　rapidly,　becoming　the　main　driving　force　in　local　economic　growth.　The　number　of　tourists　on　weekends　and　holidays　usually　increases　significantly,　which　puts　great　pressure　on　traffic　and　scenic　area　management.　This　paper　collects　data　from　relevant　toll　stations　and　analyzes　the　characteristics　and　scale　of　passenger　flow,　making　a　comparative　analysis　of　passenger　flow　changes,　which　shows　that　weather　and　holidays　are　the　main　factors　affecting　the　passenger　flow　scale.　Average　passenger　flow　increase　during　holidays　is　over　75%,　but　during　adverse　weather　conditions,　passengers　flow　drops　significantly,　by　as　much　as　5%-30%.　Through　the　analysis　of　passenger　flow　distribution　and　its　influencing　factors,　the　traffic　impact　model　around　the　scenic　spot　can　be　studied,　and　data　support　for　formulating　traffic　organization　and　management　measures　during　the　peak　season　and　holidays　can　be　provided.
