摘　　要：通过对海南省陵水县规模化种植、肥料施用、畜禽养殖、有机肥使用等情况进行数据收集与实地调研,了解陵水规模化农业生产种养情况,计算农用地完全消纳畜禽养殖产生的有机肥用量。结合耕地畜禽负荷预警值标准,发现当预警值取0.45时,陵水县临界畜禽养殖量为1 781 916头当量生猪,表明实际养殖量处于环境承载范围内。该结论为达到陵水县种养平衡提供了理论依据。The data collection and field survey of large-scale cultivation, fertilizer use, and livestock and poultry farming in Lingshui County, Hainan Province were made to understand the situation of plantations and animal farming in large-scale agricultural production in Lingshui. The amount of organic fertilizer produced by livestock and poultry farming in the agricultural land was calculated and compared with the livestock and poultry load warning level in farmland. The results showed that when livestock and poultry load warning value was 0.45, the critical livestock and poultry farming capacity in Lingshui was 1781916 heads of equivalent pigs. This showed that the actual amount of animal farming in Lingshui County was within the carrying capacity of the environment. This result might provide basis for the balance between plantations and animal farming in Lingshui.
