    摘要:

    生猪养殖产生的粪污是农业面源污染的主要污染源之一。在红壤区,由于土壤酸度强、磷素固定能力强,粪污不当还田易导致养分利用效率低与二次污染风险加剧。当前畜禽粪污资源化利用过程中存在种养脱节、安全利用技术体系不完善、经济性驱动机制缺失、可持续运营机制保障薄弱等关键瓶颈,构建“粪污集中处置+分散资源化利用”的红壤区适配型协同治理模式,通过系统优化畜禽养殖空间布局、强化粪污处理技术创新、完善粪肥安全利用体系、加强监管执法效能、构建政策激励与市场运作协同机制,明确界定政府部门、养殖主体和第三方企业的权责关系,形成“政策引导-市场驱动-主体参与”的良性循环机制,再通过科学布局、健全标准、多元激励、市场运作,形成系统化、区域化的畜禽粪污资源化利用体系,为红壤区养殖粪污高效循环利用与面源污染防控提供系统化路径,对实现养殖废弃物高效循环和面源污染防控具有重要意义。

    Abstract:

    Swine feces produced by pig farming is one of the main sources of agricultural non-point source pollution. In the red soil region, due to the strong acidity of the soil and its strong phosphorus fixation capacity, improper return of swine feces to the fields can easily lead to low nutrient utilization efficiency and an increased risk of secondary pollution. There are numerous bottlenecks in the process of resource utilization of swine feces, including disconnection between crop growing and livestock breeding, inadequate safe use technologies, a lack of economic drivers, and poor sustainable run mechanism support. Establishing a red soil zone adapted synergistic treatment model of ‘concentrated animal feces disposal + scattered resource utilization’, through systematic optimization of livestock farming spatial distribution, enhanced innovation in manure treatment technologies, establishment of comprehensive manure utilization standards, rigorous enforcement of environmental regulations, and development of synergistic policy-market coordination mechanisms, the livestock and poultry industry can transition toward environmentally sustainable development. This integrated approach facilitates the transformation of agricultural waste into valuable resources while mitigating environmental pollution risks, ultimately fostering a circular economy paradigm within the animal husbandry sector. Clear definition of rights and liabilities of governmental agency, farming entity and third-part company, forming a sound cycle mechanism of ‘policy guiding-market driving-key players participating’, and formulating of systematic and regional livestock feces resource utilization systems through scientific layout, sound and complete criteria and standards, multiple incentives and market operation, they are the important ways to solve effectively the problem of livestock farming pollution in red soil region.
