| 摘 要： | 以贵州省现有10个大型灌区作为评价对象，选取8个影响因素作为评价指标，建立投影寻踪聚类模型，并根据各样本综合投影值及给定的分级标准对各灌区灌排保障能力进行评价。评价结果表明：贵州省现有大型灌区灌排保障能力总体上处在较差到一般水平，离高效节水农业还有一定差距。

| Abstract: | Ten large-scale irrigation district in Guizhou are selected as the evaluation objects,eight factors are selected as the evaluation index and the projection pursuit cluster model is established in this paper.Also,the irrigation support capability is evaluated according to the integrated projection value of each sample and grading standard.The evaluation result shows that the irrigation support capability of the existing large-scale irrigation district in Guizhou is at the poor to general level and there is a... |
