摘要

一般来说,灌溉系统的决策者会优先考虑种植多种作物,以确保充足的粮食供应和最大化经济利润,但却忽略了生态恢复能力。本研究提出了一个新颖可靠的多目标框架,旨在最大限度地减少多种作物之间的配水差异,从而解决与灌溉时间和配水空间相关的冲突。为了评估所提模型的可行性,采用了可靠性评价技术来检验与可用水量和分配给不同作物的水量(C 值)的约束条件相对应的配水政策的冲突率。接下来,为了评估可靠的多目标最优模型,我们考察了扎扬德赫鲁德流域三个分区中四种作物--饲料、西瓜、小麦和葡萄--的配水差异,扎扬德赫鲁德流域是伊朗高原中部一个缺水的流域。随后,考虑到水资源保护政策被忽视,本研究调查了其他观点对水资源分配差异和冲突领域的影响。最终结果表明,葡萄对耗水量的敏感度较低,而西瓜的敏感度最高。在冲突领域,伦贾纳特市的敏感度最低。

Enhancing Disparity in Water Distribution within Irrigation Systems Aimed at Improving the Conflict Domain under Alternative Perspectives: A Reliable Multi-Objective Framework
In general, decision makers in irrigation systems prioritize the cultivation of diverse crops to ensure sufficient food supply and maximize economic profit, while overlooking ecological resilience. This study proposes a novel reliable multi-objective framework designed to minimize disparities in water distribution between multi-crops, thereby addressing conflicts related to irrigation timing and distribution space. To assess the feasibility of the proposed model, a reliability evaluation technique is employed to examine the conflict ratio of the water distribution policy corresponding to constraints concerning the available water and the water allocated to various crops (C-value). Next, to evaluate the reliable optimal multi-objective model, we examined the disparity of water distribution among four crops—fodder, watermelon, wheat, and grape—cultivated in three sub-areas of the Zayandehroud watershed, a watershed experiencing water shortage in the center of the Iranian plateau. Subsequently, given the overlooking of water conservation policies, this study investigates the impact of alternative perspectives on the disparity of water distribution and the conflict domain. The final results indicate that grapes exhibit lower sensitivity to water consumption, whereas watermelon is the most sensitive. In terms of the conflict domain, the city of Lenjanat recorded the least sensitivity.
