基于WEAP-MODFLOW耦合模型的泾惠渠灌区水资源系统韧性评估
Resilience assessment of water resources system in Jinghuiqu Irrigation District based on WEAP-MODFLOW coupled model
摘要
Abstract
Analyzing and quantifying the resilience of water resource systems in irrigation areas can lay the foundation for drought planning and drought risk management.It is of great significance to rational adjustment of agricultural planting structures and water supply sequences in irrigation areas,alleviating the contradiction between water supply and demand contradiction,and promoting agricultural produc-tion.By introducing the concept of water resources systems resilience,based on the WEAP-MODF-LOW coupling model,the resilience of the irrigation area's water resources system in response to drought was quantitatively calculated,and a new method was proposed for assessing the drought resist-ance of the irrigation area,which took into account the ability of the irrigation area's water resources system to recover from drought conditions,and improved the shortcomings of resilience quantification in the evaluation of resilience in the past.Taking the Jinghuiqu Irrigation District in Shaanxi Province as an example,the water resources system model of the irrigation district was constructed based on WEAP-MODFLOW,and the resilience of 24 sub-regions in the irrigation district was quantitatively calculated,and the resilience improvement strategies of each sub-region were analyzed considering multiple scenarios.The results show that the resilience of water resources system in irrigation districts is mainly related to regional water supply priority and land use.Different regions have different sensitivi-ties to resilience enhancement measures,and targeted resilience enhancement strategies should be a-dopted.The resilience of the irrigation areas can be improved by up to 30％by making full use of sur-face water in the rainy season and groundwater in the dry period,The regional resilience improvement rate is 1.92 times and 1.67 times that of the surface water priority and groundwater supply methods,re-spectively.Different sub-regions have different sensitivities to resilience improvement strategies.The improvement rate is higher in the sub-regions with lower resilience,and the difference in growth rate in the research scenario is up to 15％.Through the water resource system resilience assessment of the irri-gation area,vulnerable sub-regions can be identified,and the effectiveness of the resilience improve-ment strategies can be analyzed,and the formulation of resilience improvement plans can be developed,thereby providing decision-making support for the water resources planning of the irrigation areas.关键词
