玉米作为第三大粮食作物,其品种安全与粮食安全息息相关,目前河西制种基地面临着所育品种血缘相近的多、远缘的少、种质资源同质化等一系列问题.文章基于玉米品种安全的相关研究,结合实地调研数据,运用AHP-模糊综合评价法,从资源安全、市场安全、管理安全和技术安全4个方面出发,选取24个指标构建评价体系,对当前玉米品种安全进行了系统性评价;并对玉米品种安全的阻碍因素进行诊断,研究结果表明,玉米品种安全处于较不安全状态,原因主要在于具有核心作用的制种环节处于较不安全状态;玉米品种安全的阻碍因素的阻碍程度依次为:技术因子>市场因子>资源因子>管理因子;单项评价指标阻碍因素中种子市场监督管理体系完善程度、种子市场不当竞争、制种技术规范性、制种过程管理程度成为影响玉米品种安全的主要因素.%Maize is the third largest food , whose variety safety is closely related to the food security .At present, the Hexi seed production base is facing several problems including more close varieties , less distant varieties , germplasm resources homogenization and so on .Based on the related research of maize variety safety , combined with field survey data, we used the AHP-fuzzy comprehensive evaluation method .From the four aspects of resource security , market se-curity, management security and technology security , 24 indexes were selected to construct the evaluation system for the safety system of maize varieties;and the obstacle factors on the maize safety were investigated .The results showed that the safety of maize varieties in a state of insecurity , which was mainly due to the insecurity of core production link . The degree of obstacle factors for the safety of maize varieties showed in the order of technical factor >market factor>resource factor>management factor .In the single obstacle factor evaluation , the perfection of supervision and manage-ment system for seed market , Improper competition in seed markets , perfection, technical standard of seed production , management level of seed production process became the main factors affecting the safety of maize varieties .
