摘要: 采用多层次模糊综合评判对干旱沙区比较典型的(Ⅰ)小麦玉米带作模式、(Ⅱ)沙地衬膜种稻技术模式、(Ⅲ)沙地长龙架葡萄栽培模式、(Ⅳ)沙地果树微灌栽培模式,(Ⅴ)枣粮间作模式5种沙地利用模式进行了经济生态综合评价。讨论了在多因素决策的情况下5种模式的优先排序:Ⅱ>Ⅰ>Ⅴ>Ⅳ>Ⅲ。评判因子权值确定采用判断矩阵分析法,模糊矩阵合成运算选用加权线性变换模型M(·,+)进行求解。

关键词: 模糊评判, 利用模式, 沙地

Abstract: The method of Multi-stratum Fuzzy Comprehensive Evaluation is applied to evaluate some utilization models on sandy land in arid region. The models include (Ⅰ) the wheat-corn inter-cropping model, (Ⅱ) the technique of rice cultivation on film-bottomed sandy land, (Ⅲ) the technique of long-dragon grape cultivation, (Ⅳ) the micro-irrigation technique of fruit-trees cultivation on sandy land, and (Ⅴ) the date palm-crop inter-cropping model. The weight vectors of the evaluation factors are determined by the method of Judgment-matrix Analysis. The fuzzy matrixes operate with the weight vector model M(·,+). The result of this evaluation is Ⅱ>Ⅰ>Ⅴ>Ⅳ>Ⅲ.

Key words: Fuzzy comprehensive evaluation, utilization models, sandy land
