摘要
加强粮食综合生产能力建设是确保国家粮食安全的关键,而提高粮食生产能力最有效的途径是依靠科技进步。为此,在阐述了灰色关联分析基本原理的基础上,以1991~2005年数据为样本,对黑龙江省农机化程度和粮食生产能力两组指标进行测算,得出了影响黑龙江省主要粮食作物生产能力的具体因素,为制定省内相关农业政策提供参考。
To strengthen the building of comprehensive grain security and the most effective way to increase comprehensive production capacity is the key to ensure the country's grain grain production capability is technological progress. Thus, on the basic principles of gray correlation analysis, taking the data from 1991 to 2005 as examples, the paper estimates the correlation between two indicators which are agricultural mechanization level and grain production capability and then find out the specific factors that influence the main grain production capability of Heilongjiang Province, which would provide reference to relevant agricultural policies for Heilongjiang Province.
