基于干旱事件过程的农业旱灾风险评估研究——以辽西北为例
Research on agricultural drought disaster risk assessment based on the drought event process——A case study in Northwest of Liaoning Province
摘要
Abstract
Scientific drought disaster risk assessment is considered to be the core content and key element.in drought disaster risk management.Taking into consideration both the definition and physical mechanism of drought disaster risk,we have proposed the physical principle and conceptual model of drought disaster risk assessment based on the drought event process,and formulated a set of technical procedures correspondingly.To promote the practical application of this risk assessment method,we have carried out a case study in northwest of Liaoning Province,characterized by frequent and severe drought.The result indicates that drought disaster risk assessment based on drought event process has a strong physical meaning.This method shows a great value of future promotion,which can be employed to evaluate the potential drought loss quickly and then provide reference for drought decision making.关键词
