摘要
借助涉及经济、社会、生态的19项指标,对不同种植模式作多层次综合模糊评判。四台土以麦玉苕(中厢绿肥)综合效益最佳,综合评判值W=0.249,麦玉苕(中厢大麦)最差,W=-0.450;,一台土以麦花苕最差,W=0.316,其它三种模式综合效益差异较小。
planting models of 3 crops a year in dry land were analyzed using 19 indices regarding to economy,society and ecology with comprehensive fuzzy estimation. In land-step 4,the comprehensive effect of model 1 was the best, and its W(comprehensive estimation value)=0.249; model 3 ranked the last (W=-0. 450). In land-step 1,the comprehensive effect of model 1 was the most disappointed; the W values among other models were smaller.
