【目的】探究汕尾市畜禽粪污土地承载力现状,为当地开展种养结合、合理发展畜禽养殖规模提
供理论基础。【方法】根据《汕尾统计年鉴》的数据,对汕尾市 2017—2020 年畜禽粪污养分供应量、农作物粪
肥养分需求量以及土地承载力进行测算。【结果】2017—2020 年,汕尾市畜禽存栏量由 66.41 万头猪当量增加到
87.89 万头猪当量,其中 2020 年海丰县和陆丰市的养殖规模与前 3 年相比有较大增长;按汕尾市农作物氮、磷
养分需求总量折算的畜禽粪肥量分别由 1.52 万、0.36 万 t 增长到 1.76 万、0.41 万 t。在此期间,汕尾市畜禽养殖
所能提供的畜禽粪肥氮、磷供应量分别由 0.46 万、0.08 万 t 增加到 0.62 万、0.11 万 t;以氮、磷为基准的畜禽粪
污土地承载力指数分别为 0.30~0.35 和 0.22~0.26。【结论】汕尾市整体的畜禽养殖规模仍有较大发展潜力,汕尾
市农业部门在规划畜禽养殖业的未来发展时可根据各个区、县(市)的土地承载力情况进行相应调整。 |

【Objective】The study was conducted to investigate the status of land carrying capacity of livestock
and poultry manure in Shanwei City, and to provide a theoretical basis for the combination of planting and livestock and poultry breeding and the rational development of breeding scales.【Method】According to the data in the Shanwei Statistical
Yearbook, the nutrient supply of livestock and poultry manure, the demand of livestock and poultry manure nutrients for
crops and the land carrying capacity of Shanwei City from 2017 to 2020 were analyzed.【Result】From 2017 to 2020, the
livestock and poultry stocks in Shanwei City increased from 664 100 to 878 900 pig equivalents, and the breeding scales of
Haifeng County and Lufeng City in 2020 increased greatly compared with those in the previous three years. The total nitrogen
and phosphorus nutrient demand for crops in Shanwei City converted into livestock and poultry manure has increased from
15 200 t and 3 600 t to 17 600 t and 4 100 t, respectively. During this period, the supply of nitrogen and phosphorus in livestock
and poultry manure increased from 4 600 t and 800 t to 6 200 t and 1 100 t, respectively. The land carrying capacity indexes
of livestock and poultry manure based on nitrogen and phosphorus in Shanwei were 0.30 - 0.35 and 0.22 - 0.26, respectively.
【Conclusion】The overall scale of livestock and poultry breeding in Shanwei City still has great development potential. The
land carrying capacity could be the basis for the agricultural departments to adjust the planning of the development of livestock
and poultry breeding. |
