| 摘要: |
| 【目的】针对鄂尔多斯水资源禀赋不足等问题，探究鄂尔多斯市水资源承载能力。【方法】构建水资源-经济社会-生态环境综合评价指标体系，基于GRA-VIKOR模型对2000—2023年鄂尔多斯市各旗区水资源承载力进行综合评价，采用熵权法计算权重，以计算结果Qi作为综合评价值，并在此基础上通过障碍度模型对主要障碍因子进行识别。【结果】①2000—2023年，鄂尔多斯市水资源承载力稳步提高。准格尔旗、杭锦旗、康巴什区水资源综合评价值较低，分别为0.754、0.717、0.752，说明其水资源承载力较低；伊金霍洛旗、鄂托克前旗、乌审旗综合评价值较高，分别为0.914、0.891、0.872，说明其水资源承载力较高。②生态流量满足程度是阻碍鄂尔多斯市水资源承载力提升的主要障碍因素。【结论】2000—2023年鄂尔多斯市水资源承载力综合评价值提升，印证节水政策与技术升级的成效。生态流量满足程度是当前的主要障碍因素。为此，建议构建跨旗区的再生水调配与生态流量动态调控体系，并将生物多样性指标纳入评价模型，以完善鄂尔多斯市的水资源韧性管理决策依据。 |

| Abstract: |
| 【Objective】Ordos is located in semi-arid Northwestern China, and water scarcity and the uneven distribution of water resources constrain its sustainable socio-economic and ecological development. In this paper, we analyzed the carrying capacity of water resources in this region.【Method】A comprehensive evaluation index system of ‘water resources-socio-economy-ecological environment’ was constructed. The GRA-VIKOR model was used to evaluate the capacity of water resources at the county scale from 2000 to 2023 in the region. The entropy weight method was used to calculate indicator weights, with the computed Qi value serving as the comprehensive evaluation index. An obstacle-degree model was used to identify the main factors that limit water resource carrying capacity.【Result】①The water resource carrying capacity in Ordos steadily improved from 2000 to 2023. The comprehensive evaluation values for Jungar, Hangjin counties and Kangbashi District were relatively low at 0.754, 0.717 and 0.752, respectively, indicating lower water resource carrying capacity. In contrast, water resource carrying capacity in Yijinhuoluo, Otog Front and Uxin counties was relatively high, with evaluation values of 0.914, 0.891 and 0.872, respectively. ②Meeting the requirement for ecological water flow was identified as the most significant obstacle to improving water resource carrying capacity in the region.【Conclusion】The increase in comprehensive evaluation value of water resource carrying capacity from 2000 to 2023 in Ordos demonstrates the effectiveness of water-saving policies and technological upgrades, although meeting ecological water flow requirements remains a primary factor limiting further improvement. Establishing systems to regulate the allocation of reclaimed water resources and ecological water flow, and to incorporate biodiversity indicators, is essential for strengthening decision-making in water resource resilience management in this region. |
