Abstract: Analyse the Multi-object character of water resources utilization, Multi- object optimization model for Yellow River basin water resources with the combination of comprehensive social, economic and eco-environmental benefits is established. On the basis of multi-target flexible decision-making principle, method for multi-target flexible by-level decision-making for water resources is put forward, flexible decision-making model of real-code accelerating genetic algorithm (RAGA) is established and the research on applying it to Yellow River basin allocation is conducted, and a set of multi-target optimization allocation scheme to maintain the harmonious development of the basin water resources with high utilization efficiency is worked out.

Key words: Yellow River basin, water resources, flexible decision-making, allowable value, satisfaction degree, membership function
