Lucid waters and lush mountains are invaluable assets. Resource-saving and environmentally friendly industrial structures, production, and living modes are pursued continuously for sustainable ecological development. According to the Second National Pollution-Source Survey, agricultural non-point pollution is still the most important source of the current water pollution. In order to improve the water environment and control the pollution, the meaning and content of the eco-agricultural industrial chain was introduced. Based on this conception, the eco-agricultural industrial chain, integrating a whole circular system with different sessions of crop farming, animal breeding, agricultural product processing, and rural living, was innovatively put forward to control the agricultural non-point pollution and protect the water environment systematically for the first time in this paper. The sustainable development was realized at a large scale from the reduction and harmlessness at the source, resource utilization in the process, and ecological restoration in the end. Core techniques were innovated based on the integration of agricultural industries to achieve the high-quality and green development of agriculture. The system included ecological breeding technologies, ecological cultivation technologies, as well as rural sewage treatment and recycling technologies, in the principle of reduce, reuse, and resource. Based on this, the agricultural production changed from the traditional mode of "resources-products-wastes" to the circulation pattern of "resources-products-renewable resources-products". Thus, the final aim could be achieved to realize the material's multilevel use and energy conversion in the system. The eco-agricultural industrial chain technology was proven to be efficient to achieve both the good control of agricultural non-point pollution and an effective improvement in the water quality.
青山绿水就是金山银山。追求资源节约型、环境友好型的产业结构、生产方式和生活方式，走可持续生态发展之路。根据第二次全国污染源普查，农业面源污染仍然是当前水污染的最重要来源。为改善水环境，控制污染，本文引入了生态农业产业链的意义和内容。基于这一概念，本文首次创新性地提出了集农作物种植、动物养殖、农产品加工、农村生活等不同环节于一体的生态农业产业链，系统地控制农业面源污染，保护水环境。从源头减排无害化、过程资源利用、末端生态修复三个层面实现了大规模可持续发展。基于农业产业融合，创新核心技术，实现农业的优质绿色发展。该系统遵循“减量化、再利用、资源化”的原则，包括生态养殖技术、生态种植技术以及农村污水处理与循环利用技术。在此基础上，农业生产由传统的“资源-产品-废弃物”模式转变为“资源-产品-可再生资源-产品”的循环模式，从而实现系统内物质的多层次利用和能量的转化。生态农业产业链技术被证明能够有效控制农业面源污染，有效改善水质。
