摘要
在抽样调查数据基础上,利用模糊聚类分析对生猪散养农户行为进行了划分,给出了3种风险类型。在此基础上利用模糊粗糙集理论提取了农户饲养过程决策依赖属性和决策知识规则,通过对规则研究提取了生猪散养方式的风险结构;根据该风险结构和决策知识规则提出了降低与控制生猪散养方式风险的散养技术标准、养殖规范体系、经济规制体系。
Based on spot check data, the fuzzy cluster analysis was used to divide households＇ behaviors and three types of risk were gaven. On this hasis,the fuzzy rough set theory was used to extract the attributes of decision-making dependence and knowledge rides of decision-making in the process of farmer feed. The risk structure of live pig seatter-feed mode was extracted by researching regulation;According to the risk structure and knowledge rules of decision-making , seatter-fecd technology standard , cultivate standard system and economic regulation system of reducing and eontroling the risk of live pig scatter-feed mode were put forword.
