摘要:
种养结合型循环农业能有效发挥种植业和畜禽养殖业优势,一定程度上减少资源浪费和环境污染。东北黑土区地处冷凉干旱区,农业生产活动受气候影响显著,该区域内农业资源利用率较低、资源再利用成本较高,严重制约了区域经济发展,开展种养结合型循环农业模式可最大限度加快农业系统内物质循环,实现区域经济效益最大化。本文首先充分总结了东北黑土区内不同种养结合循环农业模式的特点,对比分析了不同模式下的生态和经济效益,再以位于松嫩平原北部厚层黑土区的海伦市为代表,结合持续高效节粮型种养循环农业模式的实际需求,重点阐述了海伦市开展种养结合型循环农业的发展历程,对比分析了传统农业生产模式与循环农业模式的经济效益,提出了海伦市种养结合循环农业的未来发展建议,以期为持续提高黑土生态系统生产力,保障黑土资源永续发展和利用提供参考依据,为东北黑土区循环农业发展提供借鉴。
Abstract:Cycled planting-livestock farming can effectively take the best advantages of farming and livestock industry, reduce the waste of resources, and prevent environmental pollution to a certain extent. The black soil region is located in the cold and arid area in Northeast (NE) China, and agricultural activities are significantly affected by climate. The lower rate of agricultural resource utilization and higher cost of resource reuse have extensively restricted the economic development in this region. Developing cycled planting-livestock farming may speed up the material circulation agricultural system to the most extent, and maximize the regional economic and ecological benefits. In this study, we summarized the characteristics of different cycled planting-livestock farming modes in the black soil region of NE China by collecting published literatures, and news in websites. The ecological and economic benefits among different modes were comprehensively compared. Then, the Hailun City, located in the heart of the black soil of the Songnen Plain in NE China, was selected as an example to demonstrate the actual demand of sustainable, high-efficient and grain-saving of the cycled planting-livestock farming. Emphasis on the development processes of the cycled agriculture mode was expounded. The economic effects between traditional agricultural mode and the cycled agriculture mode were further analyzed. Finally, suggestions of the future development of cycled planting-livestock farming in Hailun City were proposed. The paper is expected to provide some useful ideas in improving the productivity of the black soil system continuously, ensuring the sustainable development and utilization of black soil resources. This study will also provide some references for the development of cycled agriculture in the NE region.
