| Evaluation of Water Resources Vulnerability in Karst Faulted Basin of Eastern Yunnan Province |
| Due to its unique karst geological and geomorphological feature “soil is upstairs, water is downstairs” in the Eastern Yunnan faulted basin, the vulnerability of water resources has gradually become prominent. At present, water resources have become one of the important factors restricting the lives of local residents, regional economic development and ecological health. In this study, the authors selected 32 districts and counties in the Eastern Yunnan faulted basin as study cases and used the classic DPSIR model as the basis to build an evaluation model, selected 18 representative indicators, such as the utilization rate of water resources development and water resources per capita, to build an indicator system, used entropy value method and AHP to combine empowerment and, on such a basis, evaluated the vulnerability of water resources in the rocky desertification area of the karst fault basin in eastern Yunnan. The results show that the water resources vulnerability of most districts and counties in the east Yunnan fault basin are moderately and severely vulnerable, with Malong, Huaning and Luoping counties being slightly vulnerable. Luquan County, Kaiyuan City, Gejiu City and Luxi County are severely vulnerable areas. The ratio of arable land rocky desertification area, water resources per capita, water supply and storage ratio, ecological water demand satisfaction rate, and 10 000 yuan industrial value-added water consumption constitute the key factors that drive the vulnerability of water resources in this area. Through the assessment of water resource vulnerability in this area, the authors put forward the adaptive management countermeasures of water resources in the karst faulted basin in eastern Yunnan, which provides a scientific basis for effective alleviation of the water vulnerability of the region. |
