Abstract

This paper comprehensively analyzes the hazards and vulnerability of natural disasters, applies Matlab and GIS tools, deeply analyzes the spatial-temporal characteristics of the comprehensive risk of earthquake-flood disasters, and further builds a dynamic space panel model based on different spatial weight matrixes, and further analyzes them. The spatial correlation and agglomeration characteristics of comprehensive earthquake-flood hazards in Lijiang City, Chuxiong Prefecture, and Pu'er City in Yunnan Province were carried out, and comprehensive risk assessments for two types of disasters were conducted. The results show that there is a significant positive spatial correlation between the comprehensive risk of earthquake-flood disasters, and the spatial spillover effect of disaster risk will decrease with the increase of inter-regional distance, and a high-risk area of risk will be formed in Pu'er City; the spatial and temporal distribution of disasters will be uneven and the earthquake There is a big difference between disasters caused by floods and floods. Therefore, the coordination of regional disaster risk management can effectively improve disaster prevention and reduction capabilities.
