【摘要】：环境成本作为衡量环境污染程度的重要指标,是环境影响的货币化。利用湖南省生猪规模养殖数据,运用产排污系数法,借鉴农业环境成本评估方法,从生猪规模养殖污染物的实物量和价值量两方面建立生猪规模养殖环境成本评估模型,对湖南省生猪规模养殖的环境影响进行评估。结果表明:2010-2014年湖南省生猪规模养殖造成水体污染、大气污染、土壤污染、农作物重金属污染所产生的年环境成本为25.2亿元,年际间呈稳定增长的态势。由于各县市养殖规模、耕地情况等不同,地区间污染程度差异大,污染物排放量呈向养殖优势区域、密集区域发展的趋势。建立健全成本分担机制,多渠道提高养殖户对生猪规模养殖污染环境的认知水平,完善农村金融供给机制以拓宽养殖户融资渠道,有助于对生猪规模养殖环境成本实施控制。
[Abstract]:Environmental cost, as an important index to measure the degree of environmental pollution, is the monetization of environmental impact. Using the data of pig scale breeding in Hunan Province, using the method of yield and discharge coefficient, the method of agricultural environmental cost assessment is used for reference. The environmental cost assessment model of pig scale breeding was established from the aspects of physical quantity and value of pollutants in pig scale culture. The environmental impact of pig scale breeding in Hunan Province was evaluated. The results showed that the scale breeding of live pigs in Hunan Province from 2010 to 2014 resulted in water pollution, air pollution and soil pollution. The annual environmental cost caused by heavy metal pollution of crops is 2.52 billion yuan, which is increasing steadily between years. Due to the different scale of farming and cultivated land in different counties and cities, the degree of pollution varies greatly among regions. The pollutant discharge is developing to the dominant area and intensive area. Establish and perfect the mechanism of cost sharing and improve the farmers' cognition level of the pollution environment of pig scale breeding through many channels. Perfecting the rural financial supply mechanism to widen the financing channels of farmers is helpful to control the environmental cost of pig scale breeding.

【正文快照】： 生猪规模养殖活动的效果具有二重性:一方面,提高了生猪出栏率和满足了市场需求,对农户脱贫致富、地方经济发展、农村经济繁荣起到了积极作用;另一方面,规模化、标准化生猪养殖方式下,伴随着大量废弃物的集中排放,造成了严重的环境污染,包括水体污染、空气污染、土壤污染、病菌
