Abstract: Livestock and poultry farming manure is a major challenge in the control of rural environmental pollution, and the prevention and control of environmental pollution in the livestock and poultry industry is essential for the realization of rural revitalization and low-carbon recycling production. Based on survey data of 620 farmers in major meat duck production provinces, a Logit model was established to analyze the impact of environmental regulations and risk perceptions on farmers' environmentally friendly behaviors, and the mediation effect was adopted to analyze the impact of risk perception of environmental regulations on manure resource treatment behavior of farmers. The results show that environmental regulations and risk awareness both play positive roles in promoting famers' behaviors on treatment of manure. The imperative, incentive and guiding environmental regulations and the perception of risk reasons positively affects farmers' behaviors on treatment of manure. The perception of risk facts and risk causing losses are not significant, indicating that the farmers' behaviors are affected by the traditional concepts and the difference of policy-implementation among areas, and the farmers have a low awareness of manure resource utilization. Risk perception plays an mediating role in the impact of environmental regulations on famers' behaviors on treatment of manure. In order to improve farmers' awareness of environmental risks and promote environmental pollution prevention, relevant training and publicity should be carried out under the premise of effective implementation of the promotion policies, and the breeding subsidy incentive policy should be implemented based on local conditions. Therefore, the optimal allocation of environmental resources can be promoted, farmers can be encouraged to actively control pollution, and the farming benefits can be enhanced.

Key words: environmental regulation, risk perception, manure resource utilization, farmers' behavior, intermediary effect
