摘要

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.
