Evaluation of water-resource carrying capacity in Daman Irrigation District in the middle reaches of Heihe River
摘要
Abstract
To assess the state of the water-resource carrying capacity and promote the rational development of wa-ter resources in the Daman Irrigation District in the middle reaches of the Heihe River,an evaluation system with 11 indicators was constructed under the"water resources-society-economy-ecology"framework.The changing trends of the water-resource carrying capacity in the irrigation district from 2014 to 2023 were evaluated using the TOPSIS model based on game theory with combined weights.The indicators constraining the water-resource carrying capacity were identified using the obstacle degree model.Finally,the coupling coordination degree among the subsystems of water-resource carrying capacity was analyzed using the improved coupling coordina-tion degree model.The results indicate that:(1)the overall water-resource carrying capacity of the Daman Irriga-tion District is at level IV(mildly overloaded),showing a downward trend from 2014 to 2018 and an upward trend from 2019 to 2023.(2)The water-resource carrying capacity is constrained by the amount of water resourc-es per unit area,the utilization coefficient of irrigation water,the per capita water resources,and the proportion of groundwater.(3)The subsystems of water-resource carrying capacity in the Daman Irrigation District are antago-nistic;the overall coupling coordination degree is at the brink of imbalance.To ameliorate this situation,the Dam-an Irrigation District should optimize the allocation of water resources,establish a dynamic monitoring system that integrates water resources,social economy and ecology,and incorporate the index data of industrial structure into the evaluation of water-resource carrying capacity.These recommendations would improve the applicability and reliability of evaluating water-resource carrying capacities in irrigation districts.关键词
