重大动物疫病严重阻碍了我国养殖业的健康发展.养殖场区的合理防疫布局可在功能区和辅助设施建设方面保障生物安全.规模化养殖和农户的动物疫病风险认知是否促进场区防疫布局值得探讨.以我国《动物防疫条件审查办法》规定的6项防疫布局要求作为分析框架,基于全国6省331个肉鸡养殖户的调查数据,首先通过泊松回归确定了养殖户实施防疫布局要求数量的影响因素,然后运用Probit模型分析了养殖户整体防疫布局行为的影响因素.结果表明,养殖规模化能显著提高防疫布局要求个数和整体防疫布局,动物疫病风险的认知程度对增加防疫布局要求数量有显著正向影响, 但对整体防疫布局未见有效作用.与风险认知相比,养殖规模对规范防疫布局的影响较大.%Major animal epidemics have been impeding development of the livestock and poultry industries in China.Rational arrangement of epidemic prevention of animal farms ensures biosafety in construction of functional zone and construction of ancillary service.It is worth discussing whether scaled livestock farms′ and farm households′ cognition of the risk of animal epidemics would promote rational arrangement of epidemic prevention of the farms.The six mandatory requirements specified in the "Procedure for Inspecting Animal Epidemic Prevention Conditions" for arrangement of epidemic prevention were cited as framework for analysis of the data collected during the survey of a total of 331 broiler farms in six provinces.First of all, poisson regression was performed to determine factors affecting the number of requirements for farmers to lay out epidemic prevention arrangement, and then Probit model was applied to analyze factors affecting farmers′ behaviors of overall epidemic prevention arrangement.Results show that increasing of the scale of farms may significantly increase the number of requirements and overall epidemic prevention arrangement.And depth of the cognition of animal epidemic risks is significantly and positively related to the number of requirements for epidemics prevention arrangement, but not much related to the overall epidemics prevention arrangement.Compared with the cognition of the risks, scale of the farms could affect more the standard epidemics prevention arrangement.
