地质灾害系统的经济弹性及其结构研究

Economic Resilience of the Geo-disaster System and Its Structure

经济弹性是降低地质灾害系统经济损失的主要方式,如果能够对其进行准确定义和精确测量,其降低灾害损失的有效性将得到进一步增强。为此,在比较区分生态、工程、组织、规划、心理等不同学科领域弹性概念基础上,结合地质灾害系统的基本构成,对其经济弹性进行了操作化定义和数学描述。进而,在描述了地质灾害系统作用过程后,指出地质灾害系统的经济弹性是一个四维结构的概念,这对于准确衡量地质灾害经济弹性,提升其效率与潜力具有重要的作用。

Economic resilience is a major way to reduce losses from geo-disasters. Its effectiveness would be further enhanced if it could be precisely defined and measured. Therefore, based on distinguishing the concepts of resilience in the fields of ecology, engineering, organization, planning and psychology, and according to the basic structure of the geo-disaster system, operational definitions and mathematical description of the economic resilience are put forth. And thus, after describing the system of geo-disaster and its role process, it is pointed out that the e- conomic resilience of geo-disaster system is a four dimensional structure concept, which has the vital role for accu- rately measuring economic resilience of the geo-disaster, and improving its efficiency and potential.
