| 摘 要： | 以规模生猪养殖-无公害种植基地为研究对象,采用生命周期评价的方法,比较了基于种养结合的粪污直接还田、处理(堆肥、厌氧发酵)后还田以及非种养结合(肥料出售)3种情景模式的环境影响潜力。评价结果表明:通过种养结合将粪污进行农田利用,替代化学肥料的施用,对环境有积极的正效应;基于种养结合模式的养殖场粪污利用过程中,其处理后还田的环境影响潜力(2.03 kg 当量·人-1·a-1)显著低于直接还田模式(3.02 kg 当量·人-1·a-1),同时具有一定的经济效益;粪便处理环节的环境影响潜力占整体的比例最高(> 50%),其中液体粪污处理方式的选择和优化是难点和重点。建议规模化养殖场配套足够的农田以消纳养殖粪污,并发展以沼气工程为纽带的种养结合循环农业模式。

| Abstract: | In intensive agricultural region, the environmental impact potential of integrated planting and raising system has been unclear so far, which is limiting the application of integrated planting and raising technique. This study was to evaluate and compare the environmental impact potential of different treatment modes of pig manure from integrated planting and raising system using life cycle assessment(LCA)method. The treatment modes of pig manure included direct application(DA), composting and digestion-application(CDA) and composting-sale(CS). Since applying raising waste to planting fields reduced chemical fertilizer inputs, integrated planting and raising system showed positive impacts to the environment, as compared to CS. Total environmental impact potential was lower(2.03 kg eq per person per year) in CDA than in DA(3.02 kg eq per person per year). Furthermore, applications of manure to planting field had significant economic benefit. Manure treatment contributed to more than 50% of the total environmental impact potential, especially liquid slurry treatment. It thus suggests that enough farmland nearby an intensive raising farm is needed to handle animal manure. Integrated planting and raising system coupled with biogas production should be developed in the future. |
