把风险分析方法用于干旱期的水资源管理，给出了相应的风险、可靠性、恢复性和易损性等具体的风险指标。经实际应用表明，这些风险指标可以从不同的侧面反应干旱的真实危害程度，它较系统优化方法更简单易行，也便于水资源管理者制定和选择有效的干旱管理措施，可为水资源的规划和管理提供新的方法和途径。

In this paper, risk theory has been used in the management of water resources during drought period, and the corresponding indexes such as risk, reliability, resiliency and vulnerability have been given. In practice, these risk indexes can reflect the real detrimental level of drought from different aspeects.The method is simpler than system optimization, and is more convenient for water resources administrator to formulate and choice effective measures for drought management. This study can provide a new way for planning and management of water resources.
