| 摘 要： | 应用多层次多目标模糊理论与方法,建立调亏灌溉综合效益多层次多目标模糊评价模型；利用信息熵理论求得各层评价指标客观熵权,结合专家法的主观权重获得模型各层评价指标综合权重,并运用该模型对2007年秋季温室小型西瓜不同亏水处理的综合效益进行评价,结果表明,在西瓜果实膨大期进行水分亏缺处理可以一定程度上提高果实的品质,但重度和中度的水分亏缺会降低果实产量,在果实成熟期采用一定程度的水分亏缺对果实品质和产量影响不大,在苗期、开花坐果期、果实膨大期和果实成熟期分别采用0.75Ep、0.75Ep、1.25Ep和1.00Ep的灌溉标准可以获得较为理想的调亏灌溉综合效益.

| Abstract: | The multi-hierarchy and multi-objective fuzzy theory was applied to establish a multi-hierarchy and multi-objective fuzzy evaluation model of regulated deficit irrigation comprehensive benefits.Using the information entropy theory,the impersonality weights of all hierarchy evaluation indexes were obtained,and the subjective weights given by experts to attain the comprehensive weights for the method of multi-hierarchy evaluation indexes were combined,the reliability of the model evaluation results was improv... |
