耕地负荷视角下北京市畜禽废弃物资源空间转移可行性分析

Feasibility Analysis of Livestock Waste Space Transfer in Beijing Based on Livestock Waste Load in Cultivated Land

  • 摘要: 本文基于文献资料数据和统计数据,估算了2010年北京市及其郊区县、外埠主要农产品供给省份的耕地畜禽粪便负荷值,分析北京市畜禽废弃物资源空间转移的可行性。结果表明,2010年北京市耕地畜禽粪便负荷量为38.30t/hm2,超出还田限量值,而天津、河北、山东、辽宁、内蒙古等外埠蔬菜供给省份的耕地畜禽粪便负荷量分别为16.29t/hm2、15.89t/hm2、17.43t/hm2、22.45t/hm2和21.34t/hm2,低于还田限量值,京郊畜禽废弃物资源具备开展空间转移的理论可行性。在实践上,北京畜禽废弃物管理既要提高本地利用率,又要与外埠省区建立良好的合作关系,在区域农业合作框架下,着力突破管理、技术、市场、应用等关键节点,提高畜禽废弃物利用技术的成熟性和经济性、有机肥料的商品性和生产应用的积极性。

     

    Abstract: By using literature and statistical data, this paper calculated livestock waste load of Beijing, and its’ suburb and neighbor provinces in 2010, analyzed the feasibility of space transfer of livestock waste in Beijing. The livestock waste load of Beijing was 38.30t/hm2, higher than the waste returning limited value, and the values of Tianjin, Hebei, Shandong, Liaoning, and Inner Mongolia were 16.29t/hm2,5.89t/hm2,7.43t/hm2,2.45t/hm2and 21.34t/hm2, lower than the waste returning limited value. These results show the space transfer of livestock waste is feasible. In practice, Beijing livestock waste management should not only improve the local utilization rate use, but also establish good cooperation relationship with other neighbor provinces. The department should focus on strengthen management, technology, market and application of manure, to improve the maturity and economy of organic fertilizer technology, the prosperity of livestock manure and the initiative of utilizing manure.
