A　performance　auditing　evaluation　problem　of　governmental　ecological　environment　belongs　to　a　Multiple　Criteria　Decision　Making　(MCDM)　problem.　However,　we　must　use　quantitative　data　to　avoid　inconsistency　as　well　as　to　ensure　the　science　and　correctness　of　the　decision　in　an　evaluation　index　system　of　performance　auditing.　In　this　paper,　we　present　a　comprehensive　evaluation　index　system　of　performance　auditing　of　governmental　ecological　environment　based　on　fuzzy　Analytic　Hierarchy　Process　(AHP)　and　Technique　for　Order　Preference　by　Similarity　to　Ideal　Solution　(TOPSIS).　Firstly,　a　comprehensive　evaluation　index　system　of　performance　auditing　is　approved　from　the　literature　related　to　governmental　ecological　environment.　Secondly,　the　relative　weights　of　the　chosen　evaluation　indexes　of　performance　auditing　are　calculated　by　fuzzy　AHP　method.　Furthermore,　TOPSIS　method　is　adopted　to　rank　the　performance　auditing　and　improve　the　gaps　with　five　local　governments　as　an　empirical　example　As　a　new　data　analysis　method,　the　results　show　that　fuzzy　AHP　theoretical　model　and　TOPSIS　method　has　become　suitable　for　use　in　the　evaluation　of　performance　auditing　of　governmental　ecological　environment.
