Abstract: How to coordinate the interests between basin upstream and basin downstream and achieve harmonious development between basin upstream and basin downstream and maximize the interests of the entire river basin is the principal contradiction in river basin water resources compensation in China. In order to study the protection compensation mechanism of river basin water resources, this paper formulates scientific compensation standard of water protection and promotes reasonable protection and utilization of the river basin water resources. It studies the behavior and interests of the basin upstream and downstream from the perspective of the game theory, then puts forward a basin water resources protection compensation game model of administrative regulation, which is solved optimally by the Ant Colony Algorithm. The model is applied to the Jinjiang River Basin, the results show that when the upstream of Anxi, Dehua, Yongchun and Nan'an (the upper part) provides water to the downstream is 0.87×108m3, 0.75×108m3, 0.85×108m3 and 0.76×108 m3, respectively, it can obtain 0.925×108 yuan, 0.673×108 yuan, 0.949×108 yuan and 1.019× 108 yuan economic compensation, at the same time, the downstream area receives 48.765× 108 yuan benefits, the total benefit in the basin reaches the maximum. A reasonable water supply from the upstream region can significantly improve the interests of the whole basin, the downstream provides reasonable compensation funds for the upstream can make the relationship between upstream and downstream coordinated, narrow the economic and social development gap between the upstream and downstream and promote the harmonious development between the upstream and the downstream. Meanwhile, using Ant Colony Algorithm to solve the model is easy to form computer languages, which brings high computing speed, high efficiency, good convergence performance and the easy way to find the global optimal solution. Through the establishment of administrative regulation game model, the scientific computing of the amount of water transferred and the compensation standard, this paper realizes the benign interaction of water protection among the upstream and downstream, water supply area and intake area. It is of great importance and value to the establishment of protection mechanism of river basin water resources and the promotion of the unified management of river basin water resources.
