Analysis of Environmental Carrying Capacity of Livestock and Poultry Manure Based on Consumption Capacity of Land in Zixi County
摘要
Abstract
The disorderly development of livestock and poultry breeding industry will have a negative impact on the ecological environment.Scientific assessment of the regional carrying capacity of livestock and poultry manure is beneficial for scientifically planning the development of the livestock and poultry breeding industry.Taking Zixi County of Jiangxi Province as the research area,a survey was conducted on the large-scale livestock and poultry breeding farms in the county in 2021,and the annual manure production,pollutant production and loss of livestock and poultry were analyzed.The statistical analysis results showed that the main types of livestock and poultry in large-scale farming in the county were pig breeding,with about 60.33％of livestock and poultry manure pollutants coming from pigs,followed by beef cattle breeding,accounting for about 28.44％.According to the consumption capacity of land of Zixi county in 2021,the environmental carrying capacity of livestock and poultry manure of each township was analyzed.The results showed that the equivalent load level of pig manure per unit area in Hecheng town,Songshi town,Wushi town and Gaotian township was level Ⅱ,indicating that livestock and poultry manure pollution in this area had a slight impact on environment,while the load level of Gaobu Town and Zhuxi forest farm reached level Ⅲ,indicating that livestock and poultry manure pollutants in this area have a certain impact on environment,which needs to be paid attention to.关键词
