Abstract：Inorder toimprove thecomputing eficiencyandsolvingacuracyof thethirdgenerationnon-dominatedsorting geneticalgorithm（NSGA-II），theI-NSGA-Ialgorithmwasformedbyimprovingreferencepointsandoptimizingscreening strategies.TakingthesouthernwatersupplyareaofJinzhongCityasanexample，awaterresourcesoptimalalocationmodelwas constructed，andtheimprovedalgorithmandtheTOPSISsolutionmodelwereappliedtoobtainthealocationplan.Theresults show that the comprehensive performance of the improved algorithm is beter than that of NSGA- ，andhigh-quality Pareto solution setscan be obtained;thewater shortage is large under theplannedannual water supply frequencyof 75% ，andthe solutionobtainedbysetingwater-savingscenarioscansignificantlyreducelocalwaterconsumptionandecologicalenvironment pressure. The I-NSGA- Il algorithm can provide reference for multi-objective optimal allocation of regional water resources.
