Abstract: Aridity and water shortage is one of the main factors to restrict agriculture development, and the agriculture saving water irrigation is the mode of agriculture watering efficiently with the possibly little water to throw in and obtaining the possibly much more farm crop product; The article irrigates systematically the economic benefit on the agriculture saving water irrigation from theoretically for the related personnel to consult. Each cultivating unit of Xinjiang production developments corps is the hungriness or half- hungriness irrigating agriculture area and belong to artificial cultivating oasis, so the problem of being short of water is particularly outstanding. In order to make the agriculture economy keeping on the health, persistent and stable development in the cultivating units, the saving water agriculture must be developed and increase the water utilization to irrigate, increase water production efficiency in one side, save water and enlarge irrigation, improve the agriculture production technique measure, and increase the yield and quality of the food, cotton, fruit, herding; Only through the agriculture saving water measures, we may satisfy the need of the ecosystem maintenance water and keep existing environment from further depravation in ecosystem weak area, and lower the occurrence frequency of every kind of nature disaster ( such as strong wind, sandstorm, float-dust etc.), and reduce the progress degree of farmland sanding.
