摘　　要：研究农业灌溉模式对于灌区进行高效节水灌溉具有重要意义。以山东省德州市平原县为研究区,利用模糊综合评价法分析该区地下水水质状况,采用GIS研究该区2000-2009年井灌期3月和9月地下水埋深的时空变异规律,基于以上分析和该区现代化水网灌溉、井灌的现状,提出更加合理的灌溉模式。研究表明:1研究区大部分灌区的地下水水质良好,水温、pH值、盐度、碱度和矿化度均符合农田灌溉水的要求;2研究区10年间(2000-2009年)3月和9月的地下水埋深变化不大,平均埋深较小,分别为2.75和2.97m;2000、2005和2009年3月和9月地下水埋深的分布格局具有一定差异性,年际埋深普遍降低或维持原来的状态,适合地下水开采;3研究区井灌存在诸多问题,但现代化水网灌溉正在大面积推广,灌区可通过水泵并联的方式将井水输送到低压管道中,实现基于水网的井渠混灌。The research on agricultural irrigation mode is of great significance in the efficient water-saving irrigation. In this paper, Pingyuan County of Dezhou City being taken as a research area, the fuzzy compreb.ensive evaluation method was applied for the evaluation of groundwater quality and the GIS technology was used to study the spatiotemporal variation characteristics of groundwater depth in March and September between 2000 and 2009. Based on the above analysis and the current situation of irrigation by water network and well, the paper proposed more reasonable irrigation mode. The results indicated that： （1） The groundwater quality was well and the indexes, including temperature, PH value, salinity, alkalinity and mineralization degree, met the requirements of agri- cultural irrigation in most of the region. （2） During the 10 years from 2000 to 2009, the variation of groundwater depth in March and September is unapparent and the average depth was shallow, namely 2. 75m and 2.97m, respectively. The distribution patterns of groundwater depth in March and September of 2000, 2005 and 2009 were different and the interannual depth generally decreased or remained unchanged, so the groundwater was suited to be exploited. （3） Because there are many problems about well irrigation and the irrigation by the modern water network is being generalized, the groundwater can be transported from the well to low-pressure pipeline and the mixed irrigation by the well and canal can be realized in this region.
