Abstract:Drinkingwatersafetyisthebasicrequirementforsafeguardinghumanhealth.Inviewofthe
safetyofruraldrinkingwaterinGansuProvince ,weadoptedtheanalytichierarchyprocess(AHP),en
tropyweight ,improvedTOPSISmethodandobstacledegreemodelfortheanalysis.Inordertoestablisha
comprehensiveevaluationindexsystemapplicabletoGansuProvinceandprovideascientificreferencefor
theconstructionofruraldrinkingwatersafetyprojects,weevaluatedtheruraldrinkingwatersafetystatus
ofGansuProvincein2005 ,2015and2020,andcomparedthedifferencesbetweentheevaluationresults
oftheimprovedTOPSISmethodandthefuzzycomprehensiveevaluationmodel.Theresultsindicatethat
inthepast15years ,thelevelofruraldrinkingwatersafetyinGansuProvincehasgraduallyimproved.
By2020,theruraldrinkingwatersafetylevelofallcitieshasreachedthelevelofbasicsafeandabove.
ThemainobstaclestotheconstructionofruraldrinkingwatersafetyinGansuProvincearethecentralized
watersupplyrateandthetapwaterpenetrationrate.Comparedwiththefuzzycomprehensiveevaluation
model ,theimprovedTOPSISmethodhasstrongerobjectivityandsmallinformationlossinthecalculation
