| 英文摘要 | CONTEXT: Pig farming significantly impacts environmental and human health due to nitrogen (N) losses, particularly ammonia (NH3) emissions, especially in regions with high concentration of pig production. In China, national policies regulate the spatial distribution of pig farming, leading to regional variations that influence product distribution and environmental outcomes. However, our understanding of how regional policy responses affect N emissions and the associated socioeconomic costs of pig production remains limited.OBJECTIVES: This study aims to analyze changes in the spatial distribution of N emissions and the associated socioeconomic costs resulting from provincial responses to central pig production policies. Guangdong and Zhejiang, as the main pig marketing areas in China, and Hebei, as a major pig-production area, were selected to represent different regional responses. These provinces adopted distinct strategies to maintain production while mitigating environmental impacts. METHODS: The study integrates consistent county-level pig production data from 2000 to 2021 with the NUFER (nutrient fluxes in food chains, environment, and resource use)-animal model. Spatial and temporal patterns of N emissions were analyzed using geostatistical methods, and socioeconomic costs were quantified based on environmental health impact assessments. The policy-driven changes in pig production distribution were eval-uated to assess their effectiveness in mitigating environmental impacts while maintaining production levels. RESULTS & CONCLUSIONS: Our findings reveal that Guangdong strategically relocated pig production from densely populated to less populated areas to maintain pork self-sufficiency, leading to a 15 % increase in so-cioeconomic costs. Zhejiang closed many pig farms and relocated others away from watercourses to protect water quality, reducing pig production by 60 % and NH3-related costs by 20 %. Hebei province maintained its pig production levels in densely populated areas to secure pork supplies for Beijing and other surrounding cities, which led to a 25 % increase in socioeconomic costs. These results highlight that despite strong central gover-nance, provinces in China respond differently to national regulations. Provincial spatial planning is more effective than uniform policies in balancing ecological preservation and agricultural productivity. SIGNIFICANCE: This study reveals how differentiated provincial responses to national policies have shaped spatial patterns of N emissions and their socioeconomic impacts. Future policies should build on strategies like Guangdong's intra-provincial relocation approach, which balanced production with ecological capacity. Gov-ernments should strengthen spatial planning tools and establish fiscal mechanisms that compensate regions bearing higher environmental burdens. These insights provide actionable guidance for designing regionally adaptive pig production policies in China and beyond. |
