Agricultural eco-economic system coupling is an organic unit formed by the inherent interaction between agricultural ecosystem and economic system, and regulated and controlled by mankind moderate interference. Its status can be expressed by the circular chain-net structure of agricultural resources and agricultural industry. The agricultural eco-economic system in Zhifanggou watershed has gone through the process of system coupling, system conflict, system coupling, and partial conflict in high leverage, which is caused by the farmers' requirement and the state's macro-policy, economic means, and administrative means. To cope with the problems of agricultural eco-economics system coupling in Zhifanggou watershed, the optimal coupling model should be established, with tree-grass resources and related industries as the core.
农业生态经济系统耦合是农业生态系统与经济系统通过内在相互作用而形成的有机单元，并受人类适度干预的调控。其状态可通过农业资源与农业产业的循环链网结构来体现。纸坊沟流域的农业生态经济系统经历了系统耦合、系统冲突、系统耦合以及高杠杆下的局部冲突过程，这是由农民需求以及国家宏观政策、经济手段和行政手段所导致的。为应对纸坊沟流域农业生态经济系统耦合问题，应以树草资源及相关产业为核心，建立最优耦合模型。
