Abstract: The agricultural water service functions have characteristics of diversity, indivisibility and non-excludability. These characteristics determine the comprehensiveness of agriculture water utility. According to service functions of agriculture water, this paper defined the concept of agricultural water utility and its category. Furthermore, from the view of economics, this paper also explained the theory of maximizing consumer's effect of agriculture water utility. Based on above theory and the theory of multi-objective evaluation, this paper presented a framework of comprehensive evaluation of agriculture water utility, including evaluation object, index system and mathematical method.

Key words: agriculture water; service functions; utility; evaluation
