Abstract：
The optimization of the spatial layout of animal husbandry has great significance for the sustainable development of animal husbandry. However, limited research has focused on the optimization of the spatial layout of animal husbandry based on comprehensive competitive advantage evaluation and nutrient balance between planting and breeding. This study established a comprehensive competitive advantage evaluation model of animal husbandry. Based on this model, we performed comprehensive competitive advantage evaluation of animal husbandry. We further calculated the land-carrying capacity index of animal manure and potential land-carrying capacity of animal according to the principle of nutrient balance. Finally, the spatial layout of animal husbandry was optimized using Geographic Information System spatial analysis. Results showed that Harbin had obvious comprehensive competitive advantage in pig, cattle, sheep, and poultry breeding. Daqing had obvious comprehensive competitive advantage in cattle and sheep breeding. The land-carrying capacity index of animal manure of Daxing\'anling constantly exceeded 1. The potential land-carrying capacity of animal in Heilongjiang province was uneven, and most regions in Heilongjiang province had development potential of animal husbandry. The optimized target regions of the spatial layout of pig, cattle, sheep, and poultry breeding were all Harbin. A total of 77 956.03 pig equivalent in Daxing\'anling was recommended to be transferred to Harbin. Our results are useful for the spatial layout of animal husbandry, environmental pollution prevention from animal husbandry, and optimization of animal products structure.
摘要：
畜牧业空间布局的优化对畜牧业的可持续发展具有重要意义。然而,有限的研究集中在基于综合竞争优势评价和种养养分平衡的畜牧业空间布局优化上。本研究建立了畜牧业综合竞争优势评价模型。基于这个模型,进行畜牧业综合竞争优势评价。根据养分平衡原则，进一步计算了畜禽粪便的土地承载力指数和动物潜在的土地承载力。最后,利用地理信息系统空间分析对畜牧业空间布局进行了优化。结果表明,哈尔滨市在养猪方面具有明显的综合竞争优势,牛,绵羊,和家禽饲养。大庆在牛羊育种方面具有明显的综合竞争优势。大兴安岭动物粪便的土地承载力指数不断超过1。黑龙江省动物潜在土地承载力不均衡,黑龙江省大部分地区具有畜牧业发展潜力。猪空间布局的优化目标区域,牛,绵羊,家禽养殖都是哈尔滨。大兴安岭共77.956.03猪当量建议调往哈尔滨。我们的结果对畜牧业的空间布局是有用的，畜牧业环境污染防治，优化畜产品结构。
