| 摘 要： | 针对山东省农业灌溉的特点,提出了集主成分分析与系统聚类方法相结合的农业灌溉分区方法与分区指标体系。利用主成分分析法对分区指标进行了降维处理,简化了计算。在对山东省17个地市资料分析的基础上,运用系统聚类法对山东省进行了农业灌溉分区。经分区讨论,证明运用该方法分区结果较为合理,分区结果可用于山东省农业灌溉规划等的制定。

| Abstract: | In view of the characteristics of irrigated farming in Shandong province,a synthetic zoning method and the zoning indicators are put forward,which integrate the advantage of both principal components analysis and hierachical cluster means.The calculation is simplified by applying principal components analysis.Based on the analysis and calculation of the data from over 17 cities of Shandong province,applying hierachical cluster means,Shandong is zoned for the irrigated farming.Through discussing about the zo... |
