【摘要】：科学地评估旱灾风险是实施旱灾风险管理的核心内容和关键环节。本文从旱灾风险的定义和物理形成过程出发,提出了基于干旱事件过程的旱灾风险评估原理、概念模型,形成了一整套旱灾风险评估技术流程,并以位于我国东北旱灾频发、重发中心的辽西北地区为例开展了应用研究。研究表明,基于干旱事件过程的旱灾风险评估方法具有较强的物理意义,可用于快速预估一定抗旱能力条件干旱可能造成的损失,可为抗旱指挥决策提供技术支撑,具有进一步推广应用的价值。
[Abstract]:The scientific evaluation of drought risk is the core content and key link of drought risk management. Starting from the definition and physical formation process of drought risk, this paper puts forward the principle and conceptual model of drought risk assessment based on the process of drought event, and forms a complete set of drought risk assessment technical process. The study shows that the drought risk assessment method based on the drought event process has a strong physical significance and can be used to rapidly predict the possible losses caused by drought under certain drought-resistant conditions. It can provide technical support for drought-resistant command and decision-making, and has further popularization and application. Value.
