Based on the concept and connotation of the main function optimization of the river basin, this paper systematically analyzes various main function goals of the basin, and establishes the main function water resource allocation mechanism based on the evaluation index system of the main function of the basin, which is solved by genetic algorithm. The multi-objective optimization model obtained 4 types of water resource allocation plans for 9 provincial-level regions in the Yellow River Basin in 2017. The research results show that: (1) The main functions of the river basin to realize the water resource allocation mechanism makes the Yellow River Basin the largest possible water saving of 2.301 billion m3. (2) The water resources allocation mechanism for the main functions of the basin has brought about 434.448 billion yuan in production function increments, and 99.135 billion yuan in ecological function value increments, which can feed 81.948 million more people. (3) Reducing agricultural water use in Ningxia and Shandong and industrial water distribution in Inner Mongolia is crucial to the optimal distribution of water resources in the study basin.

Key words: optimization of main function of river basin, Yellow River Basin, water resources allocation, multi-objective optimization model
