院前急救时空热点分析——以醉酒为例

Space-Time Hotspot Analysis of Pre-hospital Emergency:A Case Study of Binge Drinking

介绍了时空热点分析原理,以2014年武汉市醉酒呼救资料为实例,说明时空热点分析在挖掘急救事件时空聚集规律中的应用。结果显示,武汉三镇每晚20:00~22:00时是醉酒高发时段,其中周五为高峰,周二为低谷,另外周六、周日下午15:00时左右易发醉酒。汉口醉酒密度大于武昌和汉阳。除有汉口火车站-江汉路,武昌中南路、光谷广场、黄家湖等稳定的醉酒热点区域外,另有多个随季节变化的醉酒密度高值区域。

Taking binge drinking emergency Wuhan in 2014 as a case study, the study illustrated the principle of space-time hot spot analysis and its application in pre-hospital emergency. The results show that 20:00~22:00 is the high-risk period of binge drinking every day, which peaks on Friday and touches the bottom on Tuesday. Besides, people are more often to get drunk at around 15:00 on Saturday and Sunday. The binged drinking density in Hankou is greater than that of Wuchang and Hanyang. In addition to the stable binge drinking hotspots such as Hankou Railway Station-Jianghan Road, Zhongnan Road, Guanggu Square, and Huangjia Lake, there are a few high-density areas with varying seasons.
