广西新型冠状病毒肺炎疫情特征及空间差异性研究

Study on Epidemic Characteristics and Spatial Differences of COVID-19 in Guangxi

2020新冠疫情席卷全球,通过收集2020年1月21日至3月26日期间国家卫健委及广西官方疫情数据,利用Excel、SPSS、Origin和ArcGIS10.7软件,采用统计方法和地学分析技术,分析了2020年1月21日至3月26日期间广西新冠疫情的扩散传播过程和空间差异性特征。结果表明:1)广西新冠病毒疫情呈现平缓发展趋势,输入性病例和扩散性病例的发展趋势并非同步达到峰值,具有一定的时间差;2)从疫情空间分布来看,广西新冠疫情扩散比呈现出以来宾市为圆心的同心圆分布格局;3)疫情期间人口流动为病例的流入提供了传播的可能性,但区域内不断完善的防控体系可有效减少疫情再次扩散。研究可为广西及类似区域传染性疾病防控提供决策参考。

In 2020,COVID-19 broke out all over the world.By collecting the epidemic data of the National Health Commission and the official epidemic data of Guangxi from January 21 to March 26 in 2020,using Excel,SPSS,Origin and ArcGIS10.7 software,using statistical methods and geoscience analysis techniques,analysing the spread process and spatial differences of COVID-19 in Guangxi.The results show that:(1)The novel coronavirus epidemic in Guangxi showed a trend of steady development,imported cases and diffuse cases did not reach the maximum at the same time,there was a difference in time.(2)From the perspective of spatial distribution,the spread ratio of COVID-19 in Guangxi presents a concentric circle distribution pattern with Laibin City as the center.(3)Population movement during the outbreak provides the potential for transmission of imported cases of COVID-19,but continuous improvement of the prevention and control system in the region can effectively reduce the risk of respread of the epidemic.The study can provide reference for making the decision of prevention and control of infectious diseases in Guangxi and similar regions.
