In this study,a GIS-based selection method for disaster investigation points on earthquake sites was proposed to improve the efficiency of disaster investigation on earthquake sites,enhance the scientific and rational selection of disaster investigation points,and ensure the rapid and efficient development of the disaster investigation of earthquake sites.First,the urgency and timeliness of the disaster investigation task on earthquake sites were fully considered.Then,the GIS spatial analysis function was adopted in combination with the characteristics of earthquake sites, i.e., large investigation area, tight disaster investigation task, and limited personnel. Finally, basic geographic data were subjected to spatial-temporal analysis, and the selection method for disaster investigation points on earthquake sites based on GIS was then studied and formulated. Results showed that a reasonable and correct disaster investigation method for earthquake sites can help field disaster investigators conduct disaster investigation quickly and scientifically , thus greatly improving the efficiency of on-site disaster investigation and minimizing investigation time to the greatest extent. The proposed method can provide a sufficient time guarantee for the preparation of earthquake intensity maps and disaster loss assessment reports.
