主成分分析在基地单元现代烟草农业建设水平评价中的应用

Application of Principal Component Analysis to Modern Tobacco Agriculture Construction Level Assessment in Base Unit

以广东省烟区为研究区域,以基地单元(县)为评价主体,尝试采用主成分分析法评价广东省各基地单元(县)现代烟草农业建设水平。结果表明,利用主成分分析可以有效地识别各评价指标的重要程度及各基地单元(县)现代烟草农业建设的优势和劣势;主成分分析方法可用于基地单元现代烟草农业建设水平综合评价,综合评价指标较多时,在一定程度上简化了计算工作量,评价结果符合实际,可用于指导基地单元现代烟草农业建设。

Taking the Guangdong tobacco area as a case and selecting base unit or country as the evaluation subject, the modern tobacco agriculture construction level assessment in base unit was evaluated by trying to use principal component analysis（PCA）. The results showed that PCA could identify effectively the important degree of each index and advantage and disadvantage of each base unit of county. So, PCA can be used for the comprehensive evaluation on base unit construction of modern tobacco agriculture level,especially, it can simplify the calculation to a certain extent when the evaluation has many index, and its result accords with actual conditions, and can be used to guide the construction of modern tobacco agriculture in base unit.
