In order to explore the impact of the technology adoption behavior of farmers to the different levels of agr-icultural technology, a logistic model of influencing factors for farmer willingness to participate in agricultural watersaving is established based on the investigated data of 392 farmers from the different levels of agricultural technology in the arid and semiarid area. Results show that in the environment of high level agr-itechnique diffusion, government support policies are the main factor to encourage farmers to adopt water-saving irrigation. In the environment of intermediate level agr-itechnique diffusion, the adoption of water-saving irrigation technology is easily influenced by the number of annual t raining and natural conditions in rural areas. In the environment of low level agr-itechnique dif fusion, water-saving irrigation technology is more vulnerable to the impacts of farmer. sacceptance of new technolo gies, natural conditions in ruralarea, and farmer s. riskaw areness. At last , some measures to raise the level of agricultural technology to a high level are suggested, such as intensifying government support policies, streng thening education and training, and improving regional information environment.
