摘要:
农用地生态经济系统的耦合态势是依据农用地资源与农业产业之间的循环链网结构予以表征的。该文基于农户尺度，采用耦合关联度和系统耦合度模型对纸坊沟流域农用地生态经济系统耦合关系及耦合态势进行了分析。结果表明：（1）农用地生态经济系统的耦合表现为农用地资源对农业产业的约束和农业产业对农用地资源的胁迫作用。耕地地块数、牧草利用率、化肥施用量、人口密度、人均耕地、可灌溉率是约束纸坊沟流域农业产业发展的主要因素；产业收入效应是影响农用地资源布局与利用的重要因素；（2）基于抽样调查的流域样本耦合度值基本介于0.5～0.8，系统耦合发展处于磨合耦合态势；（3）地理条件和农用地资源的分布状况成为影响农户农业生产的重要因素，同时也对农业产业的发展产生着制约作用，而相关的国家政策也对区域产业的发展起着重要的引导和制约作用。
Abstract:
The coupling trends of agriculture land eco-economic system can be characterized by the chain structure between agriculture land resources and agriculture industry. This study on coupling relations and coupling trends of agriculture land eco-economic system was carried out by coupling relational grade and coupling degree based on farm household scale. The results showed: (1) The agricultural land eco-economic system coupling was manifested as resources-restricted industry and industry-stressed resources. Plot, forage utilization, chemical fertilizers, density, Perland, duty of water were principal factor which restricted agriculture industry development. Income effect was principal factor which influence arrangement and exploitation of agriculture land resources.(2) Based on sampling survey, system coupling degree lies between 0.5～0.8 shows that the system coupling development was in running-in coupling. (3) Geographical conditions and agriculture land resources were important reasons for agriculture industry, as well as limited it. Public policy also offered advance guide and condition.
