摘　　要：以宁夏为研究对象,对宁夏粮食的综合生产能力现状进行分析,运用灰色关联度分析法探讨宁夏粮食综合生产面临的问题和影响粮食综合生产能力的因素,结果表明:①粮食综合生产能力总体呈上升态势,但区域粮食作物结构不均衡问题比较突出。存在耕地播种面积减少、劳动力流失、科技人才不足等问题。②影响宁夏粮食综合生产能力主要因素位于前3位的为单位化肥施用折纯量、农村用电量,乡村从业人员,其关联度依次为0.897、0.763、0.758。该研究成果为日后研究宁夏粮食综合生产能力建设奠定理论基础,有利于促进宁夏粮食综合生产能力建设。This article takes Ningxia as the research object,analyzes the current situation of comprehensive grain production capacity in Ningxia,and uses the grey correlation analysis method to explore the problems faced by comprehensive grain production in Ningxia and the fac⁃tors affecting the comprehensive grain production capacity.The results showed that:①The overall comprehensive grain production capacity is on the rise,but the problem of regional grain crop structure imbalance is more prominent.There are problems such as reduced arable land planting area,labor loss,and insufficient scientific and technological talents.②The top three main factors affecting the comprehensive grain production capacity of Ningxia are the net amount of unit fertilizer application,rural electricity consumption,and rural employees,with correlation de⁃grees of 0.897,0.763,and 0.758,respectively.The results of this study lay a theoretical foundation for future research on the construction of comprehensive grain production capacity in Ningxia,which is conducive to promoting the construction of comprehensive grain production ca⁃pacity in Ningxia.
