【摘要】 稻田水肥高效管理是一个多层次多指标的评价过程,本文运用多目标决策的TOPSIS法综合评价优质高产稻田水肥管理,根据各评价指标特征值之间的变异程度,利用专家评分法确定其权重并建立了评价模型。并将该方法应用于太湖地区的稻田水肥管理评价中,结果得出控制灌溉+实地氮肥管理的稻田水肥管理水平最高,常规灌溉+农民习惯施肥的稻田水肥管理水平最低。可以看出,TOPSIS法准确地筛选出了稻田高效水肥管理模式,其排序结果准确,表明TOPSIS法适宜于稻田水肥管理模式筛选。更多还原

【Abstract】 High efficient management of water and fertilizer in rice field is a multi-level evaluation process of multiple indexes.With multi -objective decision method TOPSIS (Technique for Order Preference by Similarity to Ideal Solution),the paper studies on comprehensive evaluation of water and fertilizer management at high yield and high quality rice field production.Based on the variation degree of eigenvalues for each evaluation index,an evaluation model has been established,which weight is determined by its variation coefficients. TOPSIS method is used in the evaluation of water and fertilizer management for rice field in Taihu area.It is found that the highest water and fertilizer management level is achieved with an integration of controlled irrigation and site-specific nitrogen management.On the contrary, lowest management level goes with an integration of regular irrigation and farmer conventional fertilization.So high efficient water and fertilizer management mode in rice field was screened out by TOPSIS method,by which could give a ranking result for all management modes.It demonstrates that TOPSIS method is appropriate for screening of water and fertilizer management mode for rice field.更多还原
