Spatial-temporal characteristics of geological disaster resilience in poverty and disaster-prone areas in China: A case study of Ganzi Prefecture

Abstract

Research on resilience under the influence of geological disasters in poverty and disaster-prone areas is a valuable exploration of disaster prevention and mitigation. Ganzi Prefecture occurs geological disasters frequently, resulting in loss of life, destruction of property, and harm to other infrastructure. Applying resilience can improve the ability to absorb and resolve risks, providing insights into sustainable development in Ganzi. This paper aims to assess the resilience of Ganzi Prefecture based on the widely used Baseline Resilience Indicators for Community. This modified system consists of 22 indicators divided into four dimensions: society, economy, infrastructure, and environment. The changes in disaster resilience for 18 nations in Ganzi are calculated from 2011 to 2020. Moran's I model is used to synthesize the dynamic evolvability and spatial correlation of disaster resilience. Geodetector is used to identify primary factors influencing disaster resilience. The findings reveal that (1) disaster resilience increased continuously in Ganzi during the period between 2011 and 2019, and that the gap between the disaster resilience of various counties gradually shrank. (2) The spatial distribution of disaster resilience in Ganzi varies significantly. Southeast Ganzi has greater resilience, whereas the northwest region has a considerably lower resilience. (3) The article identifies seven critical determinants of disaster resilience, and interaction factors have a significant impact on the outcomes. Based on these findings, this study proposed local regional sustainable development policy implications.

Resource and Environmental Carrying Capacity Assessment in Earthquake-Prone Area—Taking the Luding Earthquake Disaster as an Example

“…The research results show that the relative advantages and disadvantages of the carrying capacities of resources and the environment in Ganzi Prefecture have certain regional distribution characteristics. Zhou et al (2023) evaluated the geological disaster resistance capacities of various regions in Ganzi Prefecture. Their research results showed that the disaster resistance capacity of the southeastern region of Ganzi Prefecture is generally higher than that of the northwestern region, which is consistent with the results of the present study.…”
