This　paper　took　the　high-density　residential　area　in　Jiefangxi　Basin　of　Jin’an　District,　Fuzhou　City,　Fujian　Province,　China,　as　an　example.　The　PCSWMM　model　for　storm　water　simulation　was　applied　to　the　study　area　under　different　rainfall　return　periods,　rainfall　durations　and　rain　peak　coefficients,　and　the　low　impact　development　module　in　this　model　was　used　to　study　the　flood　control　effects　of　seven　different　LID　layout　scenarios　on　the　waterlogged　nodes.　The　simulations　yielded　the　following　results.　Under　different　rainfall　conditions,　the　flood　situation　of　waterlogged　node　in　the　worst　affected　area　has　been　effectively　controlled　using　single　LID　or　combined　LID　layouts.　The　peak　flow,　ponding　time　and　ponding　depth　decreased.　The　peak　suspended　sediment　concentration　of　the　node　in　vegetative　swale　layout　and　the　combination　layout　of　vegetative　swale　and　green　roof　were　higher　than　current　land　layout　scenario,　and　in　other　layouts　were　under　control.　The　reduction　effects　of　different　LID　layouts　were　more　significant　under　longer　rainfall　durations　or　lower　rainfall　return　periods.　Permeable　pavement　was　the　best　choice　in　single　LID　layout,　and　the　combination　of　permeable　pavement　and　vegetative　swale　and　green　roof　was　the　best　choice　in　combined　LID　layouts.　The　research　results　can　provide　technical　support　for　the　Sponge　City　construction　of　urban　residential　area　in　the　south　of　China,　and　provide　reference　and　suggestions　for　local　government　to　establish　relevant　codes　and　standards　©　2018,　Editorial　Board　of　China　Environmental　Science.　All　right　reserved.
