Résumé partiel
China faces the serious water shortage problem ; especially in the Northwest semi-arid and arid region. The ratio of the China’s water resource to the world’s resource is 6%, but the average water resource to the world’s average level is just 1/4, America’s 1/5, the number is 121, is one of the 13th world’s water prooest country in the world.With water resources is limited, how to reduce water (water-saving irrigation) to relieve water shortage and ensure agricultural sustainable development, it is already an extremely urgent problem.Up until now, massive literature has explored the research about the agricultural water-saving irrigation. The research of the farmer level is about the payment desire, faermer’s water use efficiency and farmer’s irrigation skill selection and so on. The research about the small-scale irrigation works governance is the jam and the SIDD mode. The research about the institution construction is concentrated on water right and water resource management. But the former research is a fat lot talk about how to conform the government, farmer group and farmer’s force to enhance the water use efficiency, realize the water management’s water saving, transportation system’ water saving and increase income with water saving.This research will analyze the water saving irrigation based on the exist literature, promote the development of agricultural water-saving irrigation of our country, offer a new kind of plan to governance water shortage.The major analysis structure which guides the whole thesis is called analysis framework-theoretical model-empirical model. Construct Polycentric Governance structure of the agricultural water-saving irrigation, how to exert peasant household, village and government’s role in agricultural water-saving irrigation, realize the agricultural water-saving irrigation together through the efforts of each participant.The first part of the thesis examines different peasant household’s water resources use efficiency and influence factor, the result shows that:peasant household’s irrigation water use efficiency is lower than farmer’s production technology efficiency. The 275 peasant households’s average irrigation water use efficiency is 22.5%, on condition that keep other input fixed, reach the actual wheat output can reduce 77.5% irrigation water at present, prove that peasant household’s water resource use efficiency is very low in 2007, the potentiality of the agricultural water-saving irrigation is relatively great. The result of the influence factor shows that:The position variable have negative impact on peasant household’s water resources use efficiency, the higher altitude, the less water consumption, the higher water resource use efficiency. Because with the rising altitude, the temperature is become lower, the lower water resource evaporation, the land that depend on irrigating supplement is less, so the peasant households’water resources in the third region is the most effective. The time from timing to irrigating the farmland of water have a negative impact on peasant household’s water resource use efficiency, indicate the farther from the third level canal, the greater unproductive losses of the water resource are, the lower water resource use efficiency is. The land fertility have a negative impact on peasant household’s water resource use efficiency, shows that in order to safeguard the high and stable yields, therefore they input more water resources, prevent the reduction of output. So, the land with the higher fertility, the lower the water resource use efficiency is.
