| Abstract_FL | Water quality is one of the main factors determining whether water possesses resource attributes.To better assess the regional groundwater resource carrying capacity,an evaluation index system incorporating water quality parameters was developed,using the Ganfu Plain irrigation district as a case study.Based on AHP(Analytic Hierarchy Process),CRITIC(Objective Weighting Method),and TOPSIS(Technique for Order of Preference by Similarity to Ideal Solution),the carrying capacity of groundwater resources was accesed,and its obstacle factors were diagnosed using the obstacle degree model.The results indicate that the groundwater resource carrying capacity in the Ganfu Plain irrigation district is relatively high,with regional ranking as follows:Jinxian County>Nanchang County>Qingyunpu District>Fengcheng City>other urban districts of Nanchang.Obstacle factors primarily include per hectare irrigation water use,precipitation infiltration,vegetation coverage,exceedance factors of toxicological indicators,per capita GDP,and dynamic water volume of groundwater.Given the significant spatial differences in obstacle factors,differentiated measures should be taken in different regions to enhance groundwater resource carrying capacity,including irrigation district projects and water supply network renovations,water quality improvement,ecological restoration,and optimized water management.The study demonstrates that water quality issues are a necessary consideration in the evaluation of groundwater resource carrying capacity,particularly in regions with poor groundwater quality. |
