Abstract:The main urban area of Weifang City is densely populated and located near the earthquake fault zone,so the earthquake risk is relatively high.In order to analyze the distribution suitability of 93 earthquake emergency shelters in the main urban area of Weifang City,this paper used ArcGIS software to carry out buffer analysis,kernel density analysis,and calculation of the nearest distance from the shelter to the fault,and adopted entropy weight method to evaluate the suitability.The analysis shows that:The number of shelters in the east of Kuiwen District,the north of Hanting District(Binhai District and Jingkai District),and the southeast of Fangzi District(Xiashan District)is obviously too small to cover effectively.The distance from the shelter to the fault is too close.67 of the 93 shelters are 0-2000 m away from the fault,accounting for 72.0%.The distance from the shelter to the supermarket has become an important factor affecting the rating of the suburban shelter.The open land on the edge of densely populated areas is a good choice for the construction of earthquake emergency shelters,and the current development and utilization are not sufficient.After a comprehensive analysis,it is concluded that the number of emergency shelters in the new functional areas in the main urban area of Weifang City is too small,and the supporting basic settings of the shelters built in this area need to be improved.It is recommended to add large shelters in places far from the fault zone.
