Abstract: Agriculture is the basis for the development of West China.The shaking off poverty of farmers is the first issue and the basic target. The ecoenvironment for the agricultural production in the Northwest Region is very poor. Thus, in the process of development of West China,the reconstruction of ecoenvironment must be closely integrated with the shaking off poverty of farmers and the agricultural, rural economic development. Taking the watercollecting ecoagriculture, which suits the regional features, not only can raise the ability of agricultural production and the farmers' income, but also gain the certain ecological benefits. The water-collecting eco-agriculture is the effective model for the sustainable development of agriculture and the progressive restoration and reconstruction of ecoenvironment in the Northwest Regions.
