Abstract: Black soil is a kind of precious cultivated land resources. However, long-term excessive intensive and unreasonable utilization makes the black soil area in northeast China face the dilemma of ‘thinning, thinning and hardening’, which poses a certain threat to China′s food security. With the increasing attention of the state to the protection of black land, the black soil area in northeast China has begun to fully implement the measures of black land protection. A certain number of farmers have participated in the protection of black land as the main body of black land protection. Based on the theory of perceived value, this paper constructed a model of farmers′ continuous participation behavior mechanism in black land protection by using the method of literature, explores the behavior process mechanism of farmers who have participated in black land protection to continue to participate in black land protection, and puts forward the coping strategies of farmers′ continuous participation behavior in black land protection based on the analysis of farmers′ behavior mechanism.
