【摘要】：为了解湖北省集约化生猪养殖系统的资源消耗及环境影响程度和识别重点生产环节造成的环境问题,基于生命周期评价(life cycle assessment,LCA)理论和Sima Pro(Version7.1.8)软件,利用Eco-indicator99生态指数法环境影响评价指标体系对湖北省集约化生猪养殖系统的环境影响进行了评估。结果表明:1)集约化养殖系统的环境单一评分为45.13分;2)主要的影响类型是土地占用(59.84%)、吸入无机物对呼吸系统损害(14.29%)、化石资源消耗(9.97%)、致癌物损害(7.80%)、酸化/富营养化(5.18%)、气候变化(1.90%);3)环境单一评分构成中仔猪生产阶段比例占17.91%,断奶后育肥阶段比例占82.09%,而且仔猪生产和育肥阶段的饲料消耗对土地占用、致癌物损害影响类型贡献较大,日常生产管理和粪污处理对吸入无机物对呼吸系统损害、酸化/富营养化、气候变化影响类型贡献较大;4)损害结果表明对人体健康影响最大环节是日常生产管理,对生态质量、资源消耗影响最大环节是饲料消耗。由此表明研究结果对生猪生产过程中减少资源消耗,采取降低环境影响的方法和措施,推动生猪养殖可持续发展有指导意义。
[Abstract]:In order to understand the resource consumption and environmental impact of intensive hog breeding system in Hubei Province and identify the environmental problems caused by key production links, based on the theory of life cycle evaluation (life cycle assessment,LCA) and Sima Pro (Version7.1.8) software, The environmental impact of intensive pig breeding system in Hubei Province was evaluated by Eco-indicator99 ecological index method. The results showed that the single environmental score of the intensive farming system was 45.13 min / 2) the main types of influence were land occupation (59.84%), respiratory damage caused by inhalation of inorganic matter (14.29%), consumption of fossil resources (9.97%), carcinogen damage (7.80%), acidification / eutrophication (5.18%). Climate change (1.90%) / 3) the proportion of piglets in production stage was 17.91 and that in postweaning fattening stage was 82.09, and the feed consumption of piglet production and fattening stage occupied land. The types of carcinogen damage have a great contribution. Daily production management and fecal disposal can damage respiratory system, acidification and eutrophication by inhaling inorganic substances. The results showed that the greatest impact on human health was daily production management, and the biggest impact on ecological quality and resource consumption was feed consumption. The results show that the research results can be used to reduce the consumption of resources, to reduce the environmental impact and to promote the sustainable development of pig breeding.
