| 中文摘要 |
| 为推动黄河“几字弯”地区水资源的高效利用与社会经济的协调发展. 基于鄂尔多斯市2010年~2023年相关数据,从水资源、社会经济和生态环境这3个维度构建水资源承载力(WRCC)评价体系,融合博弈论思想,将主观赋权的层次分析法(AHP)与客观赋权的熵权法相结合以确定指标权重,采用逼近理想解排序法(TOPSIS模型)对研究区域水资源承载力水平进行综合评价并揭示其演化特征,同时运用障碍度模型定量识别制约水资源承载力提升的主要因子. 结果表明:①2010年~2023年,研究区水资源综合承载力整体呈上升趋势,但截至2023年,各单元仍处于Ⅲ至Ⅳ级水平,尚未达到可承载标准,表明水资源承载能力仍有待提升;②区域内部呈现“核心-边缘”差异格局,中心城区承载力提升较快,至2023年已达Ⅳ级;外围地区受用水结构与政策等因素影响,承载力提升缓慢,长期维持在Ⅲ级水平;③人均水资源量、年降水量、单位农田灌溉量以及万元产值COD排放量是制约区域水资源承载力提升的主要障碍因子. 研究结果可为黄河流域资源型城市水资源优化配置、生态环境保护及社会经济可持续发展提供理论支撑与决策依据. |
| 英文摘要 |
| To promote the efficient utilization of water resources and coordinated socio-economic development in the Jizi Bend of the Yellow River, based on data from Ordos City from 2010 to 2023, a water resources carrying capacity (WRCC) evaluation system was constructed covering three dimensions: water resources, socio-economics, and ecological environment. A game-theoretic approach was applied to determine indicator weights by integrating the analytic hierarchy process (AHP) with subjective weighting and the entropy weight method with objective weighting. The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS model) was used to comprehensively assess water resources carrying capacity levels and reveal their temporal evolution, while an obstacle-degree model was employed to quantitatively identify the main factors restricting WRCC improvement. The results indicate that: ① From 2010 to 2023, the overall water resources carrying capacity in the study area showed an upward trend; however, as of 2023, all evaluation units remained at Level III to IV, falling short of the acceptable carrying standard, indicating that the water resources carrying capacity still requires improvement. ② A core-periphery spatial differentiation pattern was observed within the region. The carrying capacity in the central urban area improved rapidly, reaching Level IV by 2023, whereas in the peripheral areas, due to factors such as water use structure and policy constraints, the improvement was slow, with the carrying capacity remaining at Level III over the long term. ③ Per capita water availability, annual precipitation, irrigation water use per unit of farmland, and COD emissions per 10 000 yuan of output value were the main obstacle factors limiting the improvement of regional water resources carrying capacity. The research findings can provide theoretical support and decision-making references for the optimal allocation of water resources, ecological environmental protection, and sustainable socio-economic development in resource-based cities of the Yellow River Basin. |
