摘　　要：为了解决因长期不合理施用化肥导致的西藏土壤理化性状、营养元素、有机物质、生物学活性和重金属含量等问题,提出了以沼气为纽带的西藏农牧业清洁生产的3种模式,均以沼肥综合利用促进沼气发展为目标的,集养殖、沼气、种植为一体的循环农牧业清洁生产模式。同时,阐述了农牧业清洁生产的内涵和目标,以及西藏发展农牧业清洁生产的条件、模式、存在的问题及解决对策,为解决长期不合理施用化肥而导致的一系列问题提供思路。该研究有利于实现资源循环利用,实现生态农业与无公害农产品的生产,保护农牧区生态环境,促进西藏农牧业的可持续发展。Three models of Tibit agriculture and animal husbandry cleaner production based on biogas were proposed in this research, to solve the following problems existed in Tibit soils：soil physical and chemical characteristics, nutrient el-ements,organic matter, biological activity and the contents of heavy metals that all caused by long-term and unreasonable application of chemical fertilizer.This three model were all cleaner production models in recycling agriculture and animal husbandry and each of them combined farming,biogas and planting together, for the purpose of comprehensive utilization of biogas to promote the development of biogas.This paper illustrates the connotation and objectives of agriculture and ani-mal husbandry cleaner production, the condition, models, existing problems and solution countermeasures for Tibit to de-velop agriculture and animal husbandry cleaner production, and these informations could provide ideas to solving a series problems caused by long-term and unreasonable application of chemical fertilizer in the future.Meanwhile, it’ s advanta-geous to the achievement of recycling resources, to the realization of hazard-free food production, to the protection of ec-ological environment of farm and pastoral areas.At last, promotes sustainable development of agricultural and animal hus-bandry industries in Tibet.
