Abstract: As the principal microeconomic entity of agricultural production,the farmer's chemical fertilizer using behavior is the main factor affecting the agricultural environment.Through a sampling survey of 16 regions (320 farmer households) in Sichuan,the results are as follows: dosages of nitrogenous fertilizer and phosphorus fertilizer are used excessively;the structure of fertilizer distribution is not proportional;and the methods of using fertilizer are unscientific etc.Thus,the agricultural environment has been destroyed seriously.Based on the survey,the main factors influencing the farmers' chemical fertilizer using behavior are probed into,such as the Per capita annual income,the educational level and the application of agricultural techniques.Finally,some recommendations for fertilization and environment protection are put forward.

Key words: farmers, fertilizer using behavior, environment-protecting policy
