摘要

20世纪以来，畜牧业在快速发展的同时也带来了一系列的环境问题。基于排泄系数法，对2000-2011年北京市畜禽粪便及其产生的养分和污染物进行了估算。并对北京市各功能区农田负荷变化和环境污染预警值进行了估算。结果表明:牛粪污染最严重，占48.645%;城市功能扩展区耕地负荷最低，仍超过30 t/hm2的限制;生态开发保护区(怀柔、平谷和密云)的R值大于1，面临的污染压力最大。

Farmland Load and Environmental Risk Assessment of Livestock Manure in Beijing

Since the 20 th century, livestock industry has brought a series of environmental problems along with its rapid development. In this paper, based on the excretion coefficient method, the amount of livestock manure and generated nutrients and pollutants in Beijing during 2000—2011 were estimated. The change of farmland load and the warning value of environmental pollution in each functional area in Beijing were also estimated. The results showed that the most serious manure pollution was cattle(cow and beef) manure, which accounted for 48.645%;expanded urban function area had the lowest farmland load,which was still over the limitation of 30 t/hm2,the R values in ecological development and conservation areas(Huairou, Pinggu and Miyun) were over 1, in which faced the greatest pollution pressure.

期刊介绍： "China Animal Husbandry Magazine" was founded in 1953. It is a comprehensive guidance journal of animal husbandry under the supervision of China Association for Science and Technology, sponsored by China Animal Husbandry and Veterinary Medicine Association, and supported by China Agricultural University. It is included in many databases such as the National Chinese Core Journal Database, China Science and Technology Core Journal Database, China Academic Journal Comprehensive Evaluation Database, China Core Journal (Selection) Database, and VIP. On October 22, 2020, the Golden Apple RCCSE "China Academic Journal Evaluation Research Report" (Sixth Edition) jointly issued by the China Science and Education Evaluation Institute of Hangzhou Dianzi University, the China Science Evaluation Research Center of Wuhan University, the Wuhan University Library, and the China Science and Education Evaluation Network was officially announced. Among the 90 "Animal Husbandry and Veterinary" journals in the country, "China Animal Husbandry Magazine" was rated as "RCCSE China Authoritative Academic Journal (A+)".
