摘要: 基于主成分分析理论研究油料作物生产影响因子的评价方法, 以福建省宁化县为例, 选取11个指标进行主成分分析, 从中提取2个主成分对宁化县油料作物生产的影响因子进行研究。结果表明, 播种面积与经济发展水平、人口数量是制约宁化县油料作物产量的主要因素, 为此对宁化县油料作物生产提出了针对性的对策建议。Abstract: Taking Ninghua County in Fujian province as an example, the research was based on the theory of principal component analysis of oil crops production impact assessment methods.Eleven indexes of principal components were studied and two main components were selected for analysis on the influence of the Ninghua oil crop yield.The results showed that the planting area, level of economic development and population were the main factors which constrained Ninghua County oil crops production.Corresponding countermeasures and suggestions were put forward on the basis of the above study.
