| Abstract: | The paper predicts that the amount of water resource is demanded for prataculture development in five mail pastoral areas in 2010 based on analysis of condition and distribution of grassland resource, productive force and animal bearing capacity of grassland, condition and exploit potentiality of water resource, and the demand of national economy development and increasing farmer income in five mail pastoral areas. The results indicate that the farmer income will be 3000 yuan and the income of animal husbandry will be 2584 yuan, the total amount of animal husbandry will be 164.13 million sheep-unit, the total demand amount of forage will be 119.82 billion kilograms in 2010. But the total amount of practice product of forage is only 100.3 billion kilograms and satisfy the forage need of 137.05 million sheep-unit. So the demand amount of forage that satisfying the forage need of 27.08 million sheep-unit will be 19.5 billion kilograms solved by developing .the irrigated grassland and the demanded amount of water resource will be 4.39-8.63 billion m3 in 2010. |
