| 摘要: |
| 【目的】为构建南方丰水山区水资源脆弱性评价模型及厘清其演变规律。【方法】本文以湘西州水资源系统为研究案例，选择水资源脆弱性为研究方法，基于VSD框架构建3个维度（暴露度、敏感性和适应能力）15个指标的评价指标体系，采用投影寻踪法和综合云模型构建评价模型，开展2011 -2018年湘西州水资源脆弱评价。【结果】2011 -2018年，湘西州水资源脆弱性指标根据发展趋势可分为4种类型，其中长期较好类指标包括农业用水量、工业用水量、居民用水量、水功能区水质达标率；稳步提升类指标包括生态环境用水量、森林覆盖率、大中型水库蓄水量、污水回收处理率、堤防长度；逐步下降或未有提升类指标包括接待旅游总收入、有效灌溉面积；波动较大类指标包括产水系数、人均水资源量、年降雨量、地下水用水抽取量。湘西州水资源脆弱性综合评价整体呈现中度脆弱向弱脆弱发展的趋势。【结论】评价结果与湘西州水资源发展趋势相符，该模型可用于南方丰水山区水资源脆弱性评价及分析。 |

| Abstract: |
| 【Objective】In order to explore the evolution rules of the water resources vulnerability of the southern wet mountain region. 【Method】The paper took Xiangxi Tujiazu & Miaozu Autonomous Prefecture as an example, the water resource vulnerability evaluation index system with exposure, sensitivity, and adaptation was developed based on the VSD model, it included 3 hierarchies and 15 indicators. And the evaluation model was developed based on the projection pursuit-cloud model. 【Result】The evaluation result showed that the trend of water resources vulnerability of Xiangxi Autonomous Prefecture is divided into four categories which include the category of keeping good, category of continuous improvement, category of continuous getting worse, and category of fluctuation. The category of keeping good include agricultural water consumption, industrial water consumption, residential water consumption and rate of water quality compliance; the category of continuous improvement include eco-environmental water demand, forest coverage rate, water storage of large and medium-sized reservoirs, sewage recovery rate, and length of embankments; category of continuous got worse include tourism revenue, effective irrigation area; category of fluctuation include water yield coefficient, per capita water resources, yearly rainfall, and groundwater water withdrawals. The trend of comprehensive evaluation changed from moderate vulnerability to weak vulnerability as the work of aquatic ecological civilization, the system of the river-leader and model river have been carried out in Xiangxi Prefecture. 【Conclusion】The result was consistent with the actual situation in Xiangxi Autonomous Prefecture, which shows the model is feasible and reasonable for analysis of water resources vulnerability in the southern wet mountain region. |
