In　view　of　the　difficult　problems　in　the　complex　factors　of　urban　comprehensive　disaster　risk　assessment　and　the　inconsistency　of　the　single　method　evaluation　results,　the　evaluation　index　system　of　urban　comprehensive　disaster　risk　is　constructed　based　on　the　criteria　of　disaster　risk,　social　economic　vulnerability　and　fortification　level.　The　idea　of　combination　evaluation　is　instructed　using　the　four　combinations　of　Mean　method,　Borda　method,　Compeland　method　and　Fuzzy　Borda　method　to　evaluate　the　different　results　of　the　three　evaluation　methods:　Fuzzy　number　stochastic　simulation　method　(FSS),　weighted　summation　method　(WSM)　and　set　pair　analysis　method　(SPA).　The　Spearman　rank　correlation　coefficient　is　used　as　the　test　standard　and　repeated　iteration,　then　a　comprehensive　risk　assessment　model　of　urban　comprehensive　disaster　based　on　cyclic　revision　mode　is　established　and　the　comprehensive　disaster　risk　level　ranking　and　grade　division　of　31　cities,　municipalities　and　autonomous　regions　in　China　were　given.　It　provides　a　theoretical　and　practical　basis　for　the　indepth　identification　of　urban　comprehensive　disaster　risk　levels.　©　2019,　World　Research　Association.　All　rights　reserved.
