The invention relates to an arid region desertification and salinization water resource quantity complementary potential estimation method. The method comprises the following steps: determining an arid region oasis internal secondary salinization area; determining the critical burial depth of salinized underground water; estimating the amount of water resources wasted by salinization; estimating atransition zone vegetation area predicted to be recoverable; and determining the complementary potential of desertification and secondary salinization under different water supplementing schemes. Thesituation of water resource waste after secondary salinization is analyzed, the water resource amount caused by salinization is estimated and analyzed, meanwhile, the excessive salinization water resource amount is analyzed and conveyed to the transition zone for vegetation replenishment, and the vegetation area range expected to be recovered is estimated. The method is clear in physical processand action mechanism, the e
