Allocation priority management of agricultural water resources based on the theory of virtual water

Based on the analysis of two factors including agricultural products consumption demands of residents and water resources constraints on agricultural production, paper set up the model of allocation priority of water resources in agricultural production for the first time, and obtain the allocation priority order of water resources in agricultural production in Zhejiang province. The conclusion is that the allocation of water resources should give most priority to high-grade product (vegetable), and give normal-priority to normal-grade products (fruit, grain, milk, poultry, pork, aquatic product), and give low priority to low-grade products (vegetable oil, egg, beef and mutton).
