摘要
利用描述性统计和空间分析方法研究山东省2020-01-21~2020-03-11新冠肺炎时空特征。山东省共有99个区县出现确诊病例,疫情总体呈东部和南部较重、北部较轻的空间分布特征;整体病例和本土病例无空间集聚性,输入病例存在空间集聚性,输入病例的空间集聚分布并不完全遵循与湖北省地理邻近特征;鲁东、鲁中和鲁南地区疫情扩散较重。研究结果可为防疫工作提供参考。
The COVID-19 spatial and temporal characteristics in Shandong Province were studied by descriptive statistics and spatial analysis based on the county scale from the three dimensions including overall cases,the number of imported and local cases and spread ratio.COVID-19in Shandong Province has a gender structure characterized by more males than females and an age structure characterized by the order of the middle-aged,young,and elderly.The epidemic development goes through three stages:initiation,outbreak and stabilization.The epidemic has a spatial distribution characteristic of heavier in the east and south and lighter in the north.Only imported cases show spatial clustering.Families are the main places where COVID-19 is transmitted.
