Abstract Irrigation systems have in recent years attained a higher level of variety in as such that the selection and implementation of an irrigation system is based on the physical constraints of the site area thus giving way to a much more adequate irrigation efficiency. With due regards to the water crisis in Iran and subsequent drought conditions, the implementing of similar irrigation systems in different regional conditions lacks any justification. In the Izeh plain the use of surface irrigation systems with minimal efficiency is very common. In order to implement and operate modern irrigation systems and maximize water saving, the site selection of pressurized irrigation systems was evaluated through the fusing of AHP and GIS maps for a variety of pressurized irrigation systems followed by the selecting of the best irrigation system for each region. In the current study physical and socio-economic criteria were selected as the main criterion and were then classified into several sub-criterions.A Drip irrigation system, a Gun irrigation system, a center pivot irrigation system and a linear irrigation system were selected as the options utilized when using the AHP method. The Gun and center pivot irrigation systems had the least value as they were not suitable for mountainous area. Drip and linear irrigation systems were given a higher value and were suitable for implementation in most regions. After comparing different sub-criterion, the drip irrigation system was identified as being the most suitable pressurized irrigation system for the Izeh plain.

GIS和AHP组合在伊朗伊泽平原增压灌溉系统选址中的应用

摘要 近年来，灌溉系统已经达到了更高的多样性水平，因此灌溉系统的选择和实施基于场地区域的物理限制，从而让位于更充分的灌溉效率。考虑到伊朗的水危机和随后的干旱状况，在不同地区条件下实施类似的灌溉系统缺乏任何理由。在 Izeh 平原，使用效率最低的地面灌溉系统非常普遍。为了实施和运行现代灌溉系统并最大限度地节约用水，通过融合各种加压灌溉系统的 AHP 和 GIS 地图，然后为每个地区选择最佳灌溉系统，对加压灌溉系统的选址进行了评估。在目前的研究中，物理和社会经济标准被选为主要标准，然后分为几个子标准。选择滴灌系统、枪灌系统、中心枢轴灌溉系统和线性灌溉系统作为主要标准。使用 AHP 方法时使用的选项。Gun 和中心枢轴灌溉系统的价值最低，因为它们不适合山区。滴灌和线性灌溉系统被赋予更高的价值，适合在大多数地区实施。比较不同的子标准后，
