Abstract
Using the University of Notre Dame Global Climate Adaptation Index (ND-GAIN) assessment model for reference, the assessment system and model of agricultural disaster resistance in Henan Province are constructed. The spatial characteristics of agricultural disaster resistance subsystem (vulnerability and preparedness) of 18 cities in Henan Province in 2018 were studied by using GIS technology from six perspctives such as sensitivity, exposure, emergency, management, capacity to analyze. The results show that the agricultural disaster resistance ability of Henan Province is in the middle to lower level, showing the spatial difference pattern of high in the west, low in the southeast and weak in the north and south; the difference of vulnerability index is small, and the difference of preparedness index is large; the difference in the degree of preparedness is the main reason for the obvious difference in the level of agricultural disaster resistance; the development of agricultural disaster resistance in different regions is not balanced, and the disaster resistance in Zhengzhou is the strongest, followed by Luoyang and Sanmenxia, Zhoukou and Zhumadian are less resilient.
Highlights
Agricultural disasters have profoundly affected the social stability and healthy economic development of China for a long time
Vulnerability index is measured from three aspects: The University of Notre Dame Global Climate sensitivity, exposure and adaptability, and readiness
Based on the global climate adaptation index (ND-GAIN) model of Notre Dame University in the United States, the agricultural resilience of 18 regions in Henan Province was evaluated by constructing the evaluation index system of agricultural resilience
Summary
Agricultural disasters have profoundly affected the social stability and healthy economic development of China for a long time. The American ecologist Holling creatively introduced resilience into ecosystem stability research in the 1970s, and ecosystem resilience research was more widely used in ecological environment restoration[1]; subsequently Timmerman and so on introduced resilience into the field of social and environmental change, linking resilience to vulnerability for the first time, believing resilience to be the system's ability to withstand and recover from external shocks[2]; joint national International Strategy for Disaster Reduction (UNISDR) introduced the concept of resilience into the field of disaster science as a measure of the ability of a system or community to resist or reduce the loss of natural disasters[3]. With the development of research, the ability to resist disasters has gone on Growing into a comprehensive concept that emphasizes both the intrinsic qualities of an organization or system and the ability to respond to and recover from disasters
