摘要
近年来我国生猪规模化养殖发展迅速,但在发展过程中出现了较为严重的环境污染。通过问卷调查浙江嘉兴的生猪规模养殖户,利用Tobit模型研究生猪养殖户对于粪便污染处理的影响因素,得出以下结论:随着养殖规模的扩大,两类粪便(干粪便和尿液、沼液等液态废料)处理比例会下降;养殖户家庭经营的土地面积分别与两类粪便处理比例呈正向关系,转包入耕地面积比重对粪便污染处理比例起到负向影响作用;猪舍与住所距离会影响到养殖户对于粪便污染处理比例,距离越近干粪便处理比例约大。
The development of large scaled pig breeding in recent years has resulted in serious environmental pollution.Through a questionnaire survey of pig breeders in Jiaxing City,Zhejiang Province,this paper analyzed the factors influencing pig breeders＇ excrement pollution treatment and by using Tobit model,discussed the factors that affected pig breeders in building methane tanks.The results show that：（ 1） With the upgrading of the farming scale,processing of two types of waste（ dry excrement and liquid waste such as urine and biogas slurry） will decline.（ 2） Areas of the land managed by pig breeders are positively related with the two types of waste treatment while the proportion of subcontract arable land has negative effect on excrement pollution-treatment.（ 3） The distance between piggery and residence will affect breeders＇ pollution treatment.The closer the distance,the larger proportion of the dry excrement will be treated.
