| 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. |
