摘要：

为科学规划湘潭县畜禽养殖业布局，推动种养结合循环农业发展，本研究基于2021年湘潭县种植业、养殖业数据，测算畜禽粪污产生量、养分供给量及土地消纳能力，构建了县域畜禽粪污土地承载力评价体系。结果表明：2021年湘潭县畜禽粪污总产生量折合49.99万头猪当量，其中生猪贡献36.24万头猪当量，占比72.49%；畜禽粪污氮、磷养分排泄量分别为549.92万kg和82.49万kg，经收集处理后实际供给量为349.95万kg和59.99万kg。县域68547 hm2耕地及115347 hm2农作物种植面积可承载219.58万头猪当量，承载力指数为0.23，当前养殖规模未超出土地承载上限，仍有169.59万头猪当量的盈余空间。空间分布上，中路铺镇、杨嘉桥镇、石潭镇等乡镇土地消纳能力突出，就近还田潜力面积达26983 hm2。研究明确了湘潭县种养循环的资源匹配特征与空间分异规律，为县域畜禽养殖规模调控、种养布局优化及粪污资源化利用提供科学依据，也为南方丘陵平原交错区粮猪大县的畜禽粪污治理与绿色农业发展提供参考。

Abstract:

To scientifically plan the layout of livestock and poultry breeding industry in Xiangtan County and promote the development of integrated planting and breeding circular agriculture, this study is conducted based on the basic data of crop farming and animal husbandry in Xiangtan County in 2021. According to the technical guidelines for calculation of land carrying capacity of livestock and poultry manure and feces, it systematically calculates the total amount of livestock and poultry manure generated in the county, the nutrient supply amount, and the land absorption capacity, and constructs a carrying capacity evaluation system. The results show that in 2021, the total amount of livestock and poultry manure generated in Xiangtan County was equivalent to 499,900 pigs, among which pigs contributed 362,400 pig equivalents, accounting for 72.49%. The excretion amounts of nitrogen and phosphorus nutrients in livestock and poultry manure were 5,499,200 kg and 824,900 kg respectively, and the actual supply amounts after collection and treatment were 3,499,500 kg and 599,900 kg respectively. The 68,547 hectares of cultivated land and 115,347 hectares of crop planting area in the county can carry 2,195,800 pig equivalents, with a carrying capacity index of 0.23. The current breeding scale has not exceeded the land carrying upper limit, and there is a surplus space of 1,695,900 pig equivalents. In terms of spatial distribution, towns such as Zhonglupu Town, Yangjiagqiao Town, and Shitan Town have prominent land absorption capacity, with a potential area of 26,893 hectares for nearby returning to fields. This study clarifies the resource matching characteristics and spatial differentiation law of integrated planting and breeding in Xiangtan County, provides a scientific basis for the regulation of livestock breeding scale, the optimization of planting and breeding layout and the resource utilization of manure in the county, and also provides a reference for the manure treatment and green agricultural development of major grain and pig counties in the southern hilly plain interlaced area.

Key words: livestock and poultry manure, land carrying capacity, assimilative capacity, integrated farming and planting, Xiangtan County
