| 摘要: |
| 【目的】开展黄河下游引黄灌区水安全研究，推动水资源的节约集约利用。【方法】基于“经济社会-水资源-生态环境”复合系统相互作用机理，构建了灌区水安全量化指标体系，运用模糊综合评价模型对灌区的水安全状况进行了综合评价，并将成果应用于河南省大功引黄灌区。【结果】灌区所涉及的各县（市）水安全状态中，除长垣（水安全等级由2013年基本安全转变为2017年非常安全）、封丘（水安全等级由2013年较安全转变为2017年非常安全）和滑县（水安全等级为基本安全）外，其余各县（市）水安全状态不容乐观。【结论】注重灌区水资源统一调配，充分引用黄河水改善灌区内水资源条件薄弱地区，可更好推动当地经济发展。 |

| Abstract: |
| 【Background】The double whammy facing economic development in most regions in the Yellow river basin is the increased demand for water due to the continuous socioeconomic development and the dwindled water resources. Therefore, water management in the basin needs to balance the demand for water of different regions and the water requirement of industrial production while in the meantime maintaining ecosystems services.【Objective】The purpose of this paper is to present a method to evaluate safety for water usage and apply it to irrigation districts in the lower reach of the Yellow river aimed to improve conservation and intensive use of water resources in the river.【Method】A quantitative indicator system based on interaction mechanism in the economy-society-water resources-ecological environment composite system was constructed for water safety, and a fuzzy comprehensive evaluation model was used to evaluate water safety in the irrigation districts. We tested the method by taking irrigation areas in Dagong river in Henan province as an illustrative example.【Result】The analysis showed that most counties and cities in the region are susceptible to water safety, except Changyuan where the water safety had increased from basic safe level in 2013 to very safe level in 2017, Fengqiu where water safety had increased from relatively safe level in 2013 to very safe level in 2017, and Huaxian where water safety remained unchanged at basic safe level.【Conclusion】The allocation of water resources in the irrigation districts should be improved by diverting the Yellow river water to areas scarce with water resources. |
