| 摘 要： | 在分析影响粮食生产与粮食安全的3个主要因素(耕地面积、粮播比例和粮食单产)和耕地非农化对粮食生产的影响基础上,提出了定量综合度量耕地非农化对粮食安全影响的指标——耕地非农化对粮食安全的影响度(IDfs),并探索和建立了其简便、实用、科学的测算方法,为推进该领域的深入研究奠定了基础。

| Abstract: | Based on the analysis of three main factors affecting grain production and food security(farmland area,food crops sowing area ratio and grain yield per hectare of farmland)and the impact of farmland’ non-agriculturalization on grain production,this paper put forward quantitative indicator for measuring the impact of farmland’ non-agriculturalization on food security,that called ’Impact degree of farmland’ non-agriculturalization on food security’(referred to as IDfs),explored and established its simple,practical and scientific calculation method.The research laid a necessary foundation for promoting in-depth study in this field. |
