摘　　要：微灌节水灌溉的方式较多,实际应用中必然会遇到选择一种或几种节水灌溉方式的问题,而选择时必须综合考虑诸多因素的影响,模糊数学相对优属度综合评判法是解决这类问题较为有效的方法,它使选择的节水灌溉方式更为经济、合理。结合干旱区红枣微灌中可行的滴灌、涌泉灌、微喷灌等布置了7种方式,综合考虑了经济、技术和社会三大因素以及各大要素中的子因素,利用模糊数学方法综合评判初步得出微喷灌为干旱区红枣最适宜微灌方式。Water-saving irrigation is the development direction of future agricultural irrigation and micro-irrigation is the main form. Because micro-irrigation has a few modes, so it is inevitable to select one or more of them in actual application and many factors should be comprehensively taken into account. Fuzzy-mathematics relative importance degree comprehensive evaluation method is an effective way for this kind problem. The water saving irrigation mode selected through it is more economical and reasonable. In this paper, 7 irrigation modes suitable for red jujube in drought area, including drip irrigation, surge irrigation and micro sprinkler irrigation, are collocated. Through comprehensively considering three major factors, namely economy, technology and social and their sub -factors, it is preliminarily concluded that the optimum micro-irrigation mode for red jujube in drought area is micro sprinkler irrigation by using fuzzy-mathematics method.
