基于粮食安全指标的都江堰灌区农业初始水权分配
Initial agricultural water rights allocation in Dujiangyan Irrigation District based on food security indicators
摘要
Abstract
The Dujiangyan Irrigation District is a vital base for grain and oil production.The initial allocation of agricultural wa-ter rights in this district faces challenges in balancing current and future water demand,as well as reconciling water supply bene-fits with food security.To address these issues and achieve multiple objectives—including preventing water disputes,improving water supply reliability,and prioritizing food security—this study incorporates food security indicators into the allocation frame-work.We construct a model for the initial allocation of agricultural water rights in the Dujiangyan Irrigation District that compre-hensively considers current water consumption,water supply reliability,and grain production efficiency.The model is solved using the NSGA-Ⅱ algorithm,and the initial allocation scheme is optimized by dynamically adjusting allocated water quotas from di-verse water sources across various administrative regions.The results show that the optimized allocation reduces conveyance losses by 106 million cubic meters,thereby improving water supply reliability.In addition,the model prioritizes water allocation to re-gions with higher grain production efficiency,effectively safeguarding food security within the district.The proposed model fully takes account of disparities in conveyance losses,irrigation assurance rates across sub-irrigation districts,and water productivity among administrative regions,demonstrating strong applicability in the Dujiangyan Irrigation District.It also provides a valuable reference for the initial allocation of agricultural water rights in water-rich areas of southern China.关键词
