Abstract: Social equity and cooperative game should be a precondition for cross-regional water allocation. Former water quantity eco-compensation calculation standard ignored justice and merely pursued maximum economic benefit. A water quantity compensation standard based on society mechanism has been proposed, which takes river boundary section dis charge water of the Yongding River watershed in 2007 as control baseline. Taking social justice mechanism as the foundation for the optimal water allocation process of water user alliance inside watershed, an optimal decision process of water quantity equitable distribution is provided basing on parameter interval optimal and game theory inside watershed. The solution of cooperation game is to equalize the redistribution of user’s water profit. Water quantity distribution model for maximizing the benefits of the whole water use departments in the Yongding River watershed has been built. The model makes water quantity distribution framework of cooperation game as foundation, to calculate the Shapley value of crisp and fuzzy cooperative game. In 2007, Shanxi and Hebei parts in the upper Yongding River has discharged 0.148 billion cubic meter water, according to the model calculation, downstream Beijing should make up 46.55 million yuan for upstream Shanxi and Hebei provinces.

Key words: water quantity compensation standard, social equity, cooperative game, Yongding River Watershed
