摘要:农牧复合系统具有综合资源、兼顾生态与生计、环境与经济发展的作用，是农牧交错带脱贫富民的必由之路。目前，农牧复合实践迫切需要建立可持续的运行机制。针对于此，运用农户调查、土地养分测定和农牧测产、分室模型等方法，对宁夏盐池县皖记沟村农牧复合系统的资源支持、农户农牧复合生产方式、农牧复合系统的物质流开展研究。结果表明，促进农牧复合系统发展的主要原因是资源基础和耕地、灌木林地、草地系统耦合的生产方式。目前主要生产饲草料的水浇地和柠条林地的水资源可持续性是农牧复合系统能否长期持续的关键。加强水土资源、饲草料生产和滩羊养殖之间的系统调控和整体协同，是农牧交错带农牧复合系统可持续发展的必然选择。



Abstract:An agro-pastoral complex system has functions of integrating resources and considering the balance between ecology and livelihood, and that between environmental protection and economic development at the same time. Establishing an agro-pastoral complex system is the only way to shake off poverty and enrich people's life. It is urgent to establish a sustainable operation mechanism in the practice of agro-pastoral combination at present. The present study accordingly analyzed the resource support, production mode, and material flows of the agro-pastoral complex system in the Wanjigou village, Yanchi County, Ningxia by using the different methods including household surveys, soil nutrient determination, farming and animal husbandry yield measurements, and compartment model building. Results showed that the main factors which accelerate the development of the agro-pastoral complex system were the foundations of the resources and the production mode coupled by cultivated land, bush land, and the grassland system. At present the sustainability of the water resource in the irrigated land which mainly produces the forage and that of the water resource in the bush land of Caragana were the key factors of maintaining the long-term sustainability of the agro-pastoral complex system. The inevitable choice for the sustainable development of the agro-pastoral complex system in agro-pastoral ecotone is to enhance the systematic regulation and the integrated synergy between soil and water resources, forage production, and Tan sheep production.
