西北地区畜禽粪污资源化利用模式、效应与优化路径OA

As a key livestock production base and ecologically fragile region in China,Northwest region holds dual strategic significance in ensuring livestock product supply and safeguarding ecological security through the resource utilization of animal manure.In order to resolve the conflict between the rapid development of animal husbandry and ecological conservation in Northwest China,and to promote the shift from"end-of-pipe treatment"to"resource utilization"of livestock manure,this study systematically analyzed the mainstream technical models,comprehensive effects,and challenges facing the resource utilization of livestock and poultry manure in the region.Three optimization pathways were proposed:firstly,strengthening technology integration and regional adaptation by developing and promoting applicable technologies such as low-temperature fermentation;secondly,innovating policies and market-oriented mechanisms to cultivate specialized service organizations;thirdly,implementing differentiated development strategies to establish an environmentally sustainable"farming—treatment—utilization"circular system based on environmental carrying capacity,to provide theoretical foundations and practical guidance for enhancing the quality and efficiency of livestock manure resource utilization and promoting green,high-quality development in the livestock sector across Northwest China.
