| 摘 要： | 本文在区域农业产业结构调整中土地利用选择的宏观和微观理论分析的基础上,以河北省曲周县为例,从横向和纵向对比分析了县域土地利用结构的多样性和均衡度,并具体以耕地资源的内部微观调整对县域粮食产量所产生的影响为例.结果表明:①农户和政府均为农业产业结构调整的主体,农户微观土地利用选择行为构成区域农业产业结构调整的源动力;②政府的宏观引导和农户的微观选择之间相互作用的结果反映了县域农业产业结构调整的结果;二者的性质决定了各自的行为;③耕地内部作物面积构成变化是农户微观土地利用选择的结果;比较利益的存在是耕地内部流转的主要原因,并对粮食产量变化产生一定的影响.最后提出了曲周县农业产业结构调整及粮食生产安全的政策建议.

| Abstract: | This paper, taking Qu-Zhou County of Hebei Province as a example, analyzes the land use pattern at micro-and macro-level and its impact on crop production based on the horizontal and vertical comparison of diversity and equilibrium degree of land use structure. Da-Xing County, located in Huang-Huai-Hai Plain, was selected for comparison. The result indicates that the process of agricultural structural adjustment is dominated by farmers and governments, and farmers'choices on land use at micro level are the driving forces for the structural adjustment of agricultural industry. The result of agricultural structural adjustment is reflected through the results of interactions between governmental guidance at macro-level and the farmers' choices at micro-level. Farmers'micro choices lead to the change of land use pattern embodied specifically in the change of area of crop production. Comparative advantage drives the change of land use structure and this change can definitely influence the crop yield. On the basis of analysis result, it is recommended that the government should give greater attentions to farmer's profits and land use selection in agricultural policy making. Farmers should take consideration into the relationship between utilization and maintenance of land resources, relieving the pressure of agro-ecosystem and getting the goal of harmonious development socially, economically and ecologically. |
