| 摘 要： | 【目的】 对比分析水分利用效率法、层次分析法(AHP)和优化AHP法对灌溉制度评价的特点与优劣。【方法】 采用大田试验和膜下滴灌技术,以灌水定额为变量(30.0、37.5、45.0、52.5和60.0 mm),分析水分利用效率法以及优化前后层次分析法(AHP)确定灌水定额的合理性。【结果】 水分利用效率法能大致确定45.0~52.5 mm灌水定额范围适宜膜下滴灌玉米的生长,为追求最优的产量与水分利用率只能定性的确定52.5 mm灌水定额适宜膜下滴灌玉米的生长发育。传统AHP法的评价结果能确定最优且唯一的评价值,成对比较矩阵经本领域专家多次赋值后得到层次总排序权向量Z=(0.041,0.086,0.422,0.250,0.200),即45.0 mm灌水定额适宜膜下滴灌玉米的生长。优化AHP法不仅保留传统AHP法的优点而且结合水分利用效率法弥补了其缺点,加强因素间及层次间的联系性,规避主观判断与定性分析,52.5 mm灌水定额最适宜膜下滴灌玉米生长。【结论】 优化AHP法的评价结果与传统AHP法及水分利用效率法相比更加清晰、客观、科学。

| Abstract: | 【Objective】 To compare and analyze the characteristics and advantages of water use efficiency method, analytic hierarchy process (AHP) and optimize the AHP method in evaluating irrigation system in the hope of seeking scientific and reasonable evaluation method. 【Methods】 Under field experiment conditions, irrigation quota was used as variables (30.0, 37.5, 45.0, 52.5 and 60.0 mm) to analyze the scientific rationality of water use efficiency method and irrigation quota determined by AHP before and after optimization. 【Results】 The water use efficiency method could approximately determine the 45.0-52.5 mm irrigation quota range suitable for the growth of drip irrigation maize under mulch, but in order to pursue the optimal yield and water use efficiency, 52.5 mm irrigation quota could be determined qualitatively suitable for the growth and development of maize under mulch drip irrigation. The evaluation results of traditional AHP method could determine the best and only evaluation value. The total hierarchy permutation weight vector Z= (0.041, 0.086, 0.422, 0.250, 0.200) was obtained through pairwise comparison matrix which experts in this field evaluated many times. That 45.0 mm irrigation quota was suitable for the growth of drip irrigation maize under mulch. Optimized AHP method not only retained the advantages of traditional AHP method, but also combined water use efficiency method to make up for its shortcomings. It strengthened the relationship between factors and levels, avoided subjective judgment and qualitative analysis. The evaluation results could scientifically and reasonably determine that the 52.5 mm irrigation quota was the most suitable for the growth of drip irrigation maize under mulch. 【Conclusion】 Compared with the traditional AHP method and the water use efficiency method, the evaluation results of the optimized AHP method are more clear, objective, and scientific. It also provides a scientific theoretical basis for the objective evaluation and decision-making of various problems in the future. |
