摘要
构建了成都平原粮经种植模式效率评价的指标体系,并应用数据包络分析方法对成都平原12个主要粮经种植模式的效率进行了定量评价和分析。结果表明:12种粮经复合种植模式的整体效率尚处于DEA无效,投入产出结构不合理,其平均综合效率值为0.894。早春茄子—中稻—秋黄瓜(C4)、早春西红柿—中稻—秋茄子(C7)的综合效率值为1.000,其投入产出处于最佳状态。
This paper constructed the index system of evaluating the efficiency of compound crops cultivation in Chengdu plain,and applied the data retention analysis method for quantitative assessment of efficiency of 12 mayor modes of compound crops cultivation.The result showed that the overaU efficiency of the 12 modes was in an invalid state by DEA, and the input-output structure was irrational,its average combined efficiency value was 0.894.The combined efficiency value of both early-spring eggplant--middle-season rice--autumn-cucumber （C4）and early-sprlng tomato-- middle-season rice--autumn-cucumber（CT）were 1.000,whose input-output values were the best.
