| 摘要: |
| 【目的】客观准确评价洞庭湖区灌区现代化建设水平。【方法】该研究引入驱动力-压力-状态-影响-响应（DPSIR）模型，并结合灌区现代化建设内涵，构建了灌区现代化建设水平评价指标体系，采用物元分析法对洞庭湖区铁山灌区与西湖灌区2018、2025、2035年的灌区现代化水平进行了评价。【结果】铁山灌区和西湖灌区现代化建设水平从2018年的向初级阶段转化，分别上升到2025年的向基本实现阶段转化和2035年的实现阶段。灌区现代化建设高权重指标为灌溉保证率（0.065 9）、灌溉水有效利用系数（0.063 2）和骨干灌排设施完好率（0.045 7），这3个指标可能成为影响灌区现代化建设的主导因素。物元分析评价等级显示了各指标在现代化建设中的目标达成情况以及发展潜力。【结论】铁山灌区与西湖灌区的现代化改造方案切实可行，研究结果可为洞庭湖区推进灌区现代化建设提供指导和参考。 |

| Abstract: |
| 【Objective】The irrigation districts in the Dongting Lake catchment have been undergoing a process of modernization. This paper proposes a method to assess the level of modernization in these districts.【Method】The assessment is based on the DPSIR (Driving forces-Pressure-State-Impact-Response) framework, integrated with the concept of modernized irrigation district construction. An evaluation index system was developed, and the level of modernization was assessed using the matter element analysis method. The method was applied to calculate the modernization level of the irrigation districts in Tieshan and Xihu in 2018, 2025 and 2035.【Result】The modernization levels of both districts progressed from the transformation stage in 2018 to initial completion by 2025 and full completion by 2035. Key indicators contributing to this modernization include irrigation guarantee rate (0.065 9), effective utilization coefficient of irrigation water (0.063 2), and the integrity of backbone irrigation and drainage facilities (0.045 7). These were identified as the dominant factors influencing the modernization process. The matter element analysis revealed the achievement of each goal and development potential for each index in the modernization process.【Conclusion】The modernization processes of the Tieshan and Xihu Irrigation Districts are both feasible and practically achievable. Our findings offer valuable guidance for promoting modernization of irrigation districts across the Dongting Lake catchment. |
