英文摘要： Taking Guangxi Xijiang River Basin as a typical research area, Based on comprehensive measured data, historical documents and proxy data, Formation mechanism of extreme drought events will be analysed; risk and loss assessmetn of extreme drought events has been studied using Arcview GIS platform with strong function on space analysis and overlap under changing environment. Combined with changes of the prediction results, We can provide comprehensive strategy including optimized allocation of water resource and industrial structure adjustment. The results is to provide reference and scientific basis for the planning of the national disaster prevention and mitigation, but also important practical significance to our sustainable development strategy.
