摘要
随着生猪饲养规模的不断扩大,生猪养殖造成的环境污染问题逐渐凸显。根据第一次全国污染源普查实施方案要求,选择一个规模化养猪场和一个养殖小区做为云南省养殖业污染源的典型监测点。经过测定后发现,云南省规模养猪场(小区)养殖规模、集约化程度、日粮营养、饲养管理水平和季节等都会影响污染物产生数量及系数。
With the constant expansion of feeding scale,the problem of environmental pollution caused by pig farming is increasingly prominent.According to The First National Census of Pollution Sources,we chose a large-scale farm and a farming area as the typical monitoring site for sources of pollution in Yunnan.The results showed that the amount of pollutants and the coefficient were affected by the factors as the farming scale,the degree of intensification,the nutrition of daily diet,feeding and management level as well as the season.
