摘要
针对畜禽养殖环境系统势函数状态特征,基于尖点突变理论提出一种畜禽养殖环境系统预警的方法。以畜禽养殖环境系统势函数为状态函数,建立势函数方程,构建尖点突变预警模型,确定尖点突变判别式,以畜禽养殖环境系统承载力为警情指标、污染排放相对强度和畜禽养殖量为警兆指标,对畜禽养殖环境系统实施Ⅴ级预警。结合实例分析,结果表明尖点突变的畜禽养殖环境系统预警方法具有可行性。
As for the livestock-poultry' s environmental system' s typical feature, a systematic warning approach for the livestock-poultry's environmental system is proposed on the basis of cusp catastrophe theory. Livestock-poultry's environmental system's potential function is taken as state function, potential function's equation is established and a cusp catastrophe warning model is constructed in order to ensure the discriminate of cusp catastrophe. The carrying capacity of livestock-poultry's environmental system is taken as warning instance indexes and pollution emission relative intensity and the number of poultry feeding are taken as alarm aura, then V-level warning for livestock-poultry' s environmental system is carried out. Combined with example analysis, the result shows that based on the cusp catastrophe, the warning method of livestock-poultry's environmental system's precaution is available.
