| 摘 要： | 黄土丘陵区生态环境脆弱,农民增收与生态恢复是该区域的2大主要需求。商品型生态农业能够使满足这2个需求的"行为过程"有机结合,实现产业与资源的耦合。商品型生态农业系统要素之间存在复杂的耦合关系,为此引入"结构方程模型"。通过对典型流域(村)124户农户资料的分析与建模,结果表明:农业产业对商品型生态农业系统耦合态势具有直接影响作用,即农业产业构成了农户商品型生态农业建设的主体,而"耦合态势"却决定了农户对生态环境和社会发展的认识;在"系统运行过程中",农业资源、农户环境与农业产业具有两两相关性,且农业资源与农户环境的变化通过产业的发展传递并影响到农户生态经济系统耦合态势。这一结果与商品型生态农业的理念相吻合。为此,必须提高农户对社会经济发展的感知程度,合理、有效的利用农业资源,促进产业与农业资源的优化耦合。

| Abstract: | Ecological environment is fragile,the farmers' income and ecological restoration is two main requirement in Loess Hilly and Gully region.Ecological agriculture with commodity economy can satisfy the requirement and combine behavioral process of the requirement,achieve the coupling of industry and resource.The system of ecological agriculture with commodity economy exist complex relationship among elements,so structural equation model is led in.124farmers data of typical watershed(village) was analyzed and t... |
